Proportion : The Equality of two ratios

Equation:  Values of two mathematical expressions are equal.

Formula: Mathematical relationship or rule expressed in symbols.

Explanation:

The chemical shift of a given proton is decided specifically with the aid of interactions with the nearby electrons. The most necessary thing to recognize is that when electrons are subjected to an external magnetic field, they structure their own small prompted magnetic fields in opposition to the exterior field.

Consider the methane molecule ( CH4 ) in which the four equal protons have a chemical shift of 0.23 ppm (this is a price we can look up in any chemistry reference source). The valence electrons around the methyl carbon, when subjected to B0, generate their own very small triggered magnetic area that opposes  B0 . This induced field, to a small however full-size degree, shields the close by protons from experiencing the full force of  B0 , an impact regarded as local diamagnetic shielding. In different words, the methane protons do now not quite journey the full force of  B0  - what they journey is known as  Beff , or the high-quality field, which is slightly weaker than  B0  due to the have an effect on of the close by electrons.

Temperature of gas at volume of 950 cm³ is 368.14K or 94.99⁰c.

Given,

in this question, volume occupied by gas at 10.9⁰c is 733cm³.

we have to find out temperature at which gas occupies volume of 950 cm³.

First, convert temperature from celcius to Kelvin

10.9⁰c = 10.9 + 273.15 = 284.05 K

By equation or Boyle's Law

P1 x V1 / T1 = P2 x V2 / T2

Pressure is constant here

therefore, V1 / T1 = V2 / T2

here, V1 = 733 cm³

T1 = 284.05 K

V2 = 950 cm³

we have to find out T2

So, 733 / 284.05 = 950 / T2

T2 = 284.05 × 950 / 733 = 368.14 K

= 94. 99⁰c

The mass of copper(II) sulfide formed when copper and sulfur are heated together is 167g.

The law of conservation of mass states that the mass of a substance can neither be created nor destroyed.

This law further explains that in a chemical reaction, the mass of the reactants must equal the mass of the products.

According to this question, sulfide is formed when copper and sulfur are heated together. In a reaction, 130 g of copper reacts with 45 g of sulfur.

However, after the reaction is complete, 8.0 g of unreacted sulfur remain. This suggests that the mass of sulfide produced is as follows:

(130g + 45g) - 8g = 167g

Mass of water =  15.287 grams.

The equation here will look like this:

CxHy + O2 ------->CO2 + H2O

Hydrocarbon (contains c' and 'H' alone) and O2 are the reactants in this reaction.

Water and carbon dioxide are products.

Since mass cannot be created or destroyed in an isolated system, we now know this to be true. Although it is conserved, it can change forms.

Therefore, for chemical reaction

The mass of the reactants and the mass of the products must match. Here, just forms are altered to create the product.

Consequently, according to the Mass Law of Conversion:

Mass of Reactants = Mass of Products, we might say.

[(Mass of CO2) + (Mass H2O ] = [(Mass of Hydrocarbon) + (Mass of 02)]

[10.286  + 38.265] = [33.264 g + Mass of H20]

48.551  = 33.264 + Mass of H2O.

3: A change in direction.

The cheetah is the only object that does not meet any criteria for acceleration.

The example that is not an example of acceleration is a cheetah running at a constant speed on a hunt. The correct option is option (c).

Acceleration refers to a change in velocity, either in magnitude or direction. In the case of the cheetah running at a constant speed, there is no change in velocity, so there is no acceleration.

The cheetah maintains a steady speed,  there is no change in velocity hence, it is not accelerating.
