How much heat is needed to raise the temperature of 2g of water from 10c to 20c

Answers

Answer:

41.8g

Explanation:The equation for working out the amount of thermal energy required is q=mcΔT, where q is the amount of energy, m is the mass being heated up in grams, c is the specific heat capacity of what you're heating up in joules per gram per kelvin, and ΔT is the change in temperature in degrees Celsius or Kelvin (technically it should be in Kelvin but for a change in temperature, Celsius is the same as Kelvin).In this case, the mass is 2.0g, the specific heat capacity of water is 4.18J/g/K, and the change in temperature is 5.0°C=5K, therefore the energy needed to raise it is: 5×2×4.18=41.8J.This is only theoretical though, in the real world a lot of heat would be lost to the surroundings, so it would require more energy than this.

indications for using silver diamine fluoride include low to moderate caries risk. group of answer choices true false

Answers

"True: Silver diamine fluoride is indicated for low to moderate caries risk."is a topical treatment for dental caries

Silver diamine fluoride (SDF) is a topical treatment for dental caries (tooth decay) that has been used for many years in several countries. One of the main indications for using SDF is low to moderate caries risk. SDF works by stopping the progression of caries and inhibiting the growth of bacteria that cause tooth decay. The active ingredient in SDF, silver, has antibacterial properties that help to prevent the spread of decay and promote healing. Additionally, the fluoride in SDF helps to strengthen the teeth and prevent further decay. The use of SDF has been shown to be effective in reducing caries progression in children and adults with low to moderate caries risk. As a result, SDF is a valuable tool for managing and preventing dental caries in individuals who are at low to moderate risk for the development of caries.

Answers

0.411 M  nacl concentration results when 234 ml of a 0.840 m nacl solution is mixed with 492 ml of a 0.210 m nacl solution?

The final concentration of NaCl will be the total moles of NaCl divided by the total volume in liters.

moles NaCl:  

234 mls x 1 L / 1000 ml x 0.840 mol/L = 0.196 mols NaCl

492mlx x 1 L / 1000 ml x 0.210 mol/L = 0.103mols NaCl

Total moles = 0.196 + 0.103 = 0.299 moles NaCl

Total volume (L) = 0.234 L + 0.492 L = 0.726 L

Final [NaCl] = 0.299 mols / 0.726 L = 0.411 M (3 sig. figs.)

In 250 mL of a 0.5 M NaCl solution, how many moles of sodium chloride are there?

give the structure of the principal organic product formed on reaction of benzyl bromide with sodium ethoxide.

Answers

The principal organic product formed from the reaction of benzyl bromide with sodium ethoxide is benzyl alcohol (C6H5CH2OH).

The reaction mechanism involves the deprotonation of benzyl bromide by sodium ethoxide to form the benzyloxide intermediate, which then undergoes elimination to produce benzyl alcohol and sodium bromide as the final products.

The reaction between benzyl bromide (C6H5CH2Br) and sodium ethoxide (NaOCH2CH3) can be described as follows:    

     

Deprotonation: Sodium ethoxide acts as a strong base and deprotonates the benzyl bro    mide, abstracting a hydrogen ion (H+) from the alpha-carbon. This produces a benzyloxide intermediate (C6H5CH2O-).Elimination: In this step, the benzyloxide intermediate undergoes a dehydration reaction, losing a molecule of water (H2O) to form benzyl alcohol (C6H5CH2OH) and sodium bromide (NaBr) as the final products.

The reaction between benzyl bromide and sodium ethoxide is a classic example of an alkoxide-promoted deprotonation and elimination reaction, which is a common method for synthesizing alcohols from alkyl halides.

if a substance undergoes a constant-pressure expansion at a pressure higher than its critical pressure, can it undergo a phase change? if so, what phases are involved?

Answers

No, a substance cannot undergo a phase change if it undergoes a constant-pressure expansion at a pressure higher than its critical pressure.

The critical pressure is the highest pressure at which a substance can exist in a gaseous state, and if the pressure is above this value, the substance will always remain in a supercritical fluid state, possessing properties of both a liquid and a gas. In a supercritical fluid state, the substance does not have distinct phase boundaries, so it cannot undergo a phase change. Therefore, if a substance is subjected to a constant-pressure expansion at a pressure higher than its critical pressure, it will remain in the supercritical fluid state, undergoing a smooth transition between gas-like and liquid-like behavior.

Answers

The bond with the highest stretching frequency would be the C=O (carbonyl) bond.

Stretching frequency of a bond: The mass effect on stretching frequencies is particularly evident when deuterium isotope equivalents are compared with the corresponding hydrogen functions. Thus, the stretching frequency of a free O-H bond will be 3600 cm-1, but the O-D equivalent is lowered to 2600 cm-1.

The bond with the higher stretching frequency is usually the bond with a higher bond order.

Suppose you have 100.00 ml of a solution of a dye and transfer 2.00 ml of the solution to a 100.00ml volumetric flask. after adding water to the 100.00 ml mark, you take 5.00 ml of that solution and again dilute to 100.00 ml. if you find the dye concentration in the final diluted sample is 0.000158 m, what was the dye concentration in the original solution?

Answers

The final diluted solution is 0.000158M, then the dye concentration in the original solution is 0.158 M.

When 5 ml of the solution was taken in that stage the number of moles of dye present in the solution at that time is same after diluting it with water to a volume of 100 ml.

So, Number of moles of dye in 5 ml = number of moles in final dilution

Molarity of dye in 5 ml  x Volume of solution  =  Molarity in final dilution x final volume

M x  5ml = 0.000158 x 100

M = (0.000158 x 100)/ 5

   =   0.0158/5

   = 0.00316 M

Now, the number of moles present in 2 ml of the sample = number of moles on diluting it 100 ml.

Molarity of dye in 2 ml x Volume = molarity on diluting it x volume on diluting it

M x 2 ml = 0.00316 x 100

M = (0.00316 x 100)/2

given a molecular formula, how would you calculate the molecular weight of a compound? provide an example

Answers

The molecular weight of a compound is calculated by adding up the atomic weights of all the atoms in its molecular formula.

let's consider the molecular formula of glucose, C6H12O6. To calculate its molecular weight, we need to find the atomic weight of each element in the formula and add them up.

To find the atomic weight of an element, you can look up its atomic number in the periodic table and refer to the atomic weight listed there.

Carbon (C) atomic weight = 12.01 g/mol

Hydrogen (H) atomic weight = 1.01 g/mol

Oxygen (O) atomic weight = 16.00 g/mol

So the molecular weight of glucose is calculated as:

= (6 x 12.01) + (12 x 1.01) + (6 x 16.00)

= 72.06 + 12.12 + 96.00

= 180.18 g/mol

Given silver chloride contains (p1) = 56.34 % ag by mass

Then, 1 mole of AgCl contains 0.5634 moles of Ag

1 mole of Ag is obtained from 1/0.5634 mole of AgCl

The mass of silver (Ag) = m = 165mg = 165 x 10^-6g

Answers

It would take 25.3 years for DDT in a soil sample to decompose from a concentration of 235 ppbm (parts per billion by mass) to 15 ppbm

The rate of a first-order reaction is given by:

d[DDT]/dt = -k[DDT]

Where [DDT] is the concentration of DDT, t is time, and k is the rate constant, which is related to the half -life (t1/2) by:

k = 0.693 / t1/2

For DDT with a half-life of 12 years, the rate constant can be calculated as:

k = 0.693 / (12 years) = 0.0577 / year

To find the time required to reduce the DDT concentration from 235 ppbm to 15 ppbm, we can use the integrated form of the first-order rate equation:

[DDT] = [DDT]0 * e^(-kt)

Where [DDT]0 is the initial concentration of DDT. Solving for t when [DDT] = 15 ppbm, we get:

t = (1/k) * ln([DDT]0 / [DDT]) = (1/k) * ln(235 ppbm / 15 ppbm)

Plugging in the value for k, we find:

t = (1/0.0577) * ln(235 ppbm / 15 ppbm) = approximately 25.3 years

So it would take approximately 25.3 years for the DDT concentration in the soil sample to decrease from 235 ppbm to 15 ppbm.
