Answer:
<h3>25.0 grams is the mass of the steel bar.</h3>
Explanation:
Heat gained by steel bar will be equal to heat lost by the water
Mass of steel= 
Specific heat capacity of steel = 
Initial temperature of the steel = 
Final temperature of the steel = 
Mass of water= 
Specific heat capacity of water=
Initial temperature of the water = 
Final temperature of water =
On substituting all values:
<h3>25.0 grams is the mass of the steel bar.</h3>
Answer:
Explanation:
Here, we want to describe the relationship between the volume and temperature of an ideal gas
This relationship is defined by Charles' law
From this law, we know that the volume of a given mass of gas is directly proportional to its temperature at a fixed pressure
What this means is that as long as the pressure remains unchanged, when the volume increases, the temperature increases, and when the volume decreases, the temperature decreases
These can be represented by the mathematical formula below:
One molecule of ammonia is composed of two atoms of nitrogen and three atoms of hydrogen. Option B.
<h3>What is an equation?</h3>
The term chemical equation has to do with the presentation of a chemical reaction on paper in a way that it can be easily understood. It is easy to write an equation to show what is going on in a reaction system.
Now we have the reactions as shown in the question. In this reaction which is the synthesis of ammonia and occurs industrially in the Haber process. The statement that is not true is that; one molecule of ammonia is composed of two atoms of nitrogen and three atoms of hydrogen. Option B.
