what are the signs of q,w h for this endothermic reaction taking place at constant pressure? 3o2 2o3
The endothermic reaction taking place at constant pressure: q = + , ΔH = +, w = +
Endothermic reactions are reactions that absorb heat (heat is removed from the surroundings to the system) Endothermic reactions (endo- is the prefix meaning "into"), in which heat must be transferred to the system by the surroundings.
According to the condition given in the question we have given the reaction.
3O₂ (g) → 2O₃ (g)
The reaction is endothermic which means heat is absorbed.
For any endothermic reaction, the sign is POSITIVE.
Now, if we see moles, the number of moles from the reactant side to the product side is decreasing.
If the number of moles is decreasing, then the volume should decrease.
If the volume is decreasing, it indicates that the work is done on the system.
If the work is done on the system then the sign should be always POSITIVE
Now as the heat is absorbed so the sign of q should be POSITIVE
Therefore, the correct option is q = +, ΔH = +, w = +

the most stable isotope of sr has a mass number of 88. what is the most likely mode of decay for the radioactive isotope 90sr?
The most likely mode of decay for 90Sr is beta decay. 90Sr decays to 90Y with emission of a beta particle.
Beta decay occurs when a nucleus has too many neutrons relative to protons, making it unstable. In beta decay, a neutron transforms into a proton, electron, and antineutrino. The electron, also known as a beta particle, is ejected from the nucleus with high energy, while the proton stays inside the nucleus, increasing its atomic number by 1. As a result of this transformation, the atomic number of the parent nuclide (90Sr) increases by 1, transforming into the daughter nuclide (90Y). The daughter nuclide will have the same number of protons, but one more proton than the parent, making it a different element. This process increases the stability of the nucleus, decreasing its neutron-to-proton ratio and bringing it closer to the stability line of isotopes.

a certain flask is guaranteed to deliver 5.0 x 102 ml 5%. what is the absolute uncertainty delivered by the pipette (in ml) reported to the correct number of significant figures?
The absolute uncertainty delivered by the pipette (in ml) reported to the correct number of significant figures will be 0.05 ml.
The absolute uncertainty in this case would be 0.05 x 102 ml, as the volume is guaranteed to be delivered within 5% (0.05 x 102 ml) of the total volume (5.0 x 102 ml).
The number of significant figures for 5.0 x 102 ml is 3, so the absolute uncertainty should also be reported to 3 significant figures, which would be 0.05 x 102 ml = 0.05 ml.
Three key factors contribute to the uncertainty of the pipetted volume, u(V), including repeatability (u(V,rep), pipette calibration (u(V,cal), and temperature variation (u(V), which is the uncertainty owing to the temperature difference from 20 °C) (V,temp).
The estimation of the calibration uncertainty of the pipette is frequently expressed as the estimate of the probable maximum difference of the pipette volume from the nominal volume, expressed as x. (as was done in section 4.1). Typically, the producer provides it without providing any more details regarding its coverage probability or distribution function. In this situation, it is safer to assume that the rectangular distribution is valid and to divide the uncertainty estimate by the square root of three to obtain the standard uncertainty.

how many milliliters of pure acid must be added to 150 milliliters of a 30% solution of acid to obtain a 50% solution?
To obtain a 50% solution from a 30% solution, you need to add 100 mL of pure acid to 150 mL of the 30% solution.
Calculation-
Let's call the volume of the pure acid added to the 30% solution "V".
We know that the volume of the original solution is 150 mL, and that its concentration is 30%. The concentration of the final solution, after adding the pure acid, is 50%.
The concentration of a solution can be expressed as the ratio of the amount of solute to the total volume of the solution. To find the volume of pure acid required, we'll use this expression to create two equations: one for the initial solution, and one for the final solution.
For the initial solution, we have:
(30 g acid) / (100 mL solution) = (30 g acid) / (150 mL solution)
For the final solution, we have:
(50 g acid) / (100 mL solution) = (50 g acid) / (150 mL + V mL)
We can equate the two expressions for the concentration of the solution to find V:
(30 g acid) / (150 mL solution) = (50 g acid) / (150 mL + V mL)
Cross-multiplying and solving for V, we find:
V = 150 mL * (50 g acid) / (30 g acid) - 150 mL
V = 250 mL - 150 mL
V = 100 mL

a 5.56 g sample of a solid containing ni is dissolved in 20.0 ml water. a 5.00 ml aliquot of this solution is diluted to 100.0 ml and analyzed in the lab. the analyzed solution was determined to contain 5.54 ppm ni . determine the molar concentration of ni in the 20.0 ml solution.
The molar concentration of Ni in the 20.0 mL solution is 2.37 x 10⁻⁷ M. To find the molar concentration of Ni in the 20.0 mL solution, we first need to find the number of moles of Ni in the 5.56 g sample.
Moles of Ni in the 5.56 g sample:
Ni atomic mass = 58.69 g/mol
5.56 g Ni / 58.69 g/mol = 0.095 moles Ni
Next, we need to find the concentration of Ni in the 5.00 mL aliquot of the solution that was diluted to 100.0 mL.
From the analysis, we know the Ni concentration in the analyzed solution was 5.54 ppm. So,
5.54 ppm = 5.54 mg/L = 5.54 µg/mL = 5.54 x 10⁻⁶ g/mL
The 5.00 mL aliquot was diluted to 100.0 mL, so the concentration of Ni in the 5.00 mL aliquot would be:
5.54 x 10⁻⁶ g/mL * (5.00 mL / 100.0 mL) = 2.77 x 10⁻⁷ g/mL = 2.77 µg/mL
Finally, we can find the molar concentration of Ni in the 20.0 mL solution by converting the mass of Ni in the 5.00 mL aliquot to moles:
2.77 µg Ni / 58.69 g/mol = 4.74 x 10⁻⁹ moles Ni
And then, finding the molarity (moles/L) by dividing the number of moles by the volume of the solution:
4.74 x 10⁻⁹ moles Ni / (20.0 mL x 10⁻³ L/mL) = 2.37 x 10⁻⁷ M Ni
So, the molar concentration of Ni in the 20.0 mL solution is 2.37 x 10⁻⁷ M.

three students are asked to discuss the percent error obtained from this lab and explain some sources of error that would account for the discrepancy seen, if any. which student employs correct scientific reasoning?student 1: if the reaction was not allowed to go to completion, the sodium bicarbonate would not have fully decomposed, making the final mass higher than the theoritical. student 2: if th baking soda was not heated long enough, the mass of solid product would be lowstudent 3: the student didnt weight the masses correctly therefore human error is the main source of discrepancya. student 3b. student 1c. student 2
Students who use correct scientific reasoning are Student 1 namely: If the reaction is not allowed to finish, the sodium bicarbonate will not decompose completely, making the final mass higher than the theory.Te corrct amswer is B.
If the sodium bicarbonate is not properly broken down, water and carbon monoxide will not be produced, which can be eliminated to lessen the product's mass. The product will therefore weigh heavier or have a bigger ultimate mass than predicted because of an incomplete reaction.
Given the aforementioned justifications, it is obvious that Student 2 is mistaken in this instance. This is not a scientific explanation in the instance of Student 3 and is merely a wild guess that isn't true in all circumstances.

calculate the osmotic pressure (in atm) at 19.6 degrees c of a solution made by dissolving 9.37 g of glucose in 51.5 ml of solution.
To calculate the osmotic pressure of a solution made by dissolving 9.37 g of glucose in 51.5 ml of solution at 19.6 degrees Celsius, you need to use the van't Hoff equation.
The equation is: P = (i x R x T) / (M x V), where i is the number of particles of solute (in this case, glucose molecules), R is the ideal gas constant (8.314 J/molK), T is the absolute temperature (in Kelvin, so 19.6 degrees Celsius is 292.7 K), M is the molar mass of the solute (180.16 g/mol for glucose), and V is the volume of the solution (in liters, so 51.5 mL is 0.0515 L).
Plugging these values into the equation gives us P = (2 x 8.314 x 292.7) / (180.16 x 0.0515) = 3.6 atm.

how many ml of water must be added to 300 ml of 0.75 m hcl to dilute the solution to 0.25 m? select one: a. 600 ml b. 100 ml c. 900 ml d. 300 ml
To dilute the solution to 0.25 M, ml of water must be added to 300 ml of 0.75 M HCl is a. 600 mm.
To dilute the solution from 0.75 M to 0.25 M, we need to decrease the concentration of HCl (hydrochloric acid) in the solution. We can use the formula for dilution of a solution to calculate the volume of water that must be added:
C1 * V1 = C2 * V2
Where:
C1 = initial concentration (0.75 M)
V1 = initial volume (300 ml)
C2 = final concentration (0.25 M)
V2 = final volume (V1 + V added)
Rearranging the equation to solve for V added:
C1 * V1 = C2 * V2
V2 = (C1 * V1 ) / C2
= 0.75 * 300 / 0.25
= 900
Since V2 = V1 + V added then
V added = V2 - V1
= 900 - 300
= 600
Hence, total water that must be added is a. 600 ml

which of the following is a chemical change? group of answer choices melting gold cutting a rope bending a steel rod making a snowman burning sugar
Burning sugar is a chemical change as airborne oxygen interacts with sugar, chemical bonds are destroyed and a new molecule is created.
Chemical changes occur when the molecular makeup is totally changed and a new product is created. New products are created via chemical modifications. Chemical alterations are both permanent and irreversible. It demonstrates that modifying or tweaking the experimental changes cannot undo chemical change. During a chemical change, the substance's mass varies. The mass is either added or subtracted. Energy changes occur when a chemical interaction occurs. The production of new bonds in products and the breaking of existing bonds in reactants involve different amounts of energy. When energy is released from the process, it is referred to as an exothermic reaction, and when it is absorbed, it is referred to as an endothermic reaction.
Hence, burning sugar is the chemical change as it changes it's molecular composition and completely new product is formed.
