i didnt do dis my mom has a answer key book
Explanation:
Answer :
Explanation : When diatomic hydrogen gas and diatomic nitrogen gas reacts spontaneously it forms ammonia gas as the product.
we will have the following reactions; As all the reactants and products are in the gaseous state the subscript (g) is given to the molecules.
But this is not a balanced equation, as on the right side of reactants we have 2 hydrogen atoms and 2 nitrogen atoms which gives the product which has one nitrogen and three hydrogen in the compound state.
So, balancing the equation, we get,
We multiplied 2 with the diatomic hydrogen molecule which resulted in production of 2 moles of ammonia as the product.
So, the complete balanced equation is;
H. using a pulley system can reduce the load force, over a greater distance.<span />
According to Charles' law for ideal gases, at constant pressure, the volume and temperature of a given mass of gas with same number of moles are directly proportional to each other. This means, if volume increases then temperature will also increase whereas, if volume decreases then temperature will also decrease. For this reason, a small increase in volume will increase the temperature of the gas.
Therefore,
Volume ∝ Temperature in Kelvin scale.
V ∝ T
Solution :
A cell that is concentrated is constructed by the same half reaction for the anode as well as he cathode.
We know,
In a standard cell,
the reduction half cell reaction is :
The oxidation half ell reaction :
Thus the complete reaction of the cell is :
cell =
