Answer:
The term temperature refers to the average amount of heat or the motion energy of particles in a substance. It measures the hotness and coldness of a substance. If an object has particles that move very fast, then it has a high temperature.
Temperature is different from the term thermal energy. Thermal energy is the total motion energy of particles in a substance. The movement of particles is always dependent on their number. If an object contains many particles, then it has greater thermal energy.
On the other hand, Heat is the energy that is involved in the movement of particles between objects that have different temperatures, particularly from an object with a high temperature to an object with a low temperature.
<u>Answer:</u> The value of 
for the given chemical reaction is 0.1415
<u>Explanation:</u>
Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of the products and the reactants each raised to the power their stoichiometric ratios. It is expressed as
For a general chemical reaction:
The expression for is written as:
For the given chemical equation:
The expression for for the following equation is:
We are given:
Putting values in above equation, we get:
The value of for the given chemical reaction is 0.1415
Answer:
27.03 grams
Explanation:
moles (n) = mass(m)/Molar mass(M)
moles = 1.59
mass = ?
N = 14, H = 1
M(NH3) = 14 + 3(1) = 17
Substitute the values into the equation:
nM = m
∴ m = 1.59 × 17 = 27.03
