Chemistry

Masteriza [31]3 years ago

<u>Answer:</u>

option A is correct option.

Explanation :

A spontaneous method is capable of continuing during a given direction while not having to be driven by an outdoor supply of energy.

The laws of physical science govern the direction of a spontaneous method, guaranteeing that if a sufficiently sizable amount of individual interactions are concerned, then the direction can perpetually be within the direction of enhanced entropy.

Associate in Nursing endergonic reaction (also referred to as a nonspontaneous reaction) may be a chemical change during which the quality change in free energy is positive and energy is absorbed.

Endergonic processes will be pushed or force by coupling them to extremely exergonic reactions.

ΔG = ΔH - TΔS , ΔG is amendment within the free energy, ΔH is that the amendment in total heat, ΔS is that the amendment in entropy and T is temperature in kelvin.

Spontaneity of reaction Vs total heat Vs entropy

When ΔH is negative and ΔS is positive, ΔG are going to be negative over all temperatures.

When ΔH is negative and ΔS is negative, ΔG are going to be negative at low temperatures.

When ΔH is positive and ΔS is negative, ΔG won't be negative at any temperature. There would be no spontaneous reaction.

When ΔH is positive and ΔS is positive, ΔG are going to be negative at high temperatures.

Therefore, finally it's the amendment in free energy of a reaction which may predict if a reaction is possible.

Find the GPE of 2000 kg boulder on 100 meter high.
kkurt [141]

Answer:1962kJ

Explanation:

m=2000 kg

h=100m

G=9.81m/s²

GPE=m*G*h

GPE=2000kg*100m*9.81m/s²=1,962,000J=1962 kJ

How many grams of H2 can be formed from 54.6 grams of NH3 in the following reaction? 2NH3 (g) --&gt; 3H2 (g) + N2 (g)
Strike441 [17]

Answer:

9.64g

Explanation:

The balanced equation for the reaction is given below:

2NH3 (g) —> 3H2 (g) + N2 (g)

Next, we need to calculate the mass NH3 that decomposed and the mass of H2 produced from the balanced equation. This is illustrated below:

Molar Mass of NH3 = 14 + (3x1) = 14 + 3 = 17g/mol

Mass of NH3 that decomposed from the balanced equation = 2 x 17 = 34g

Molar Mass of H2 = 2x1 = 2g/mol

Mass of H2 produced from the balanced equation = 3 x 2 = 6g.

Now, we can obtain the mass of H2 formed from 54.6g of NH3 as follow:

From the balanced equation above,

34g of NH3 decomposed to produce 6g of H2.

Therefore, 54.6g of NH3 will decompose to produce = (54.6x6)/34 = 9.64g of H2

Therefore, 9.64g of H2 can be obtained from 54.6g of NH3.
