In this problem, Charles' law is applicable since constant pressure with varying volume and temperature are given. Charles' law derived from ideal gas law is expressed as
. Subsituting V1=556 cm3, T1=278 K and T2=231 K, V2 or the new volume is 462 cm3.
Answer:
Explanation:
When carbon dioxide dissolves and reacts with water, the water and the gaseous reacts to form a dilute mixture solution of (carbonic acid ).
The reaction is
This is a forward reaction. And the symbol shows that the reaction can be reversible. It means that the reaction can be carried in forward direction as well as in the backward direction.
The reaction attains chemical equilibrium until the reactants and the products no longer changes with time.
The carbonic acid can also dissociates into carbon dioxide and water in the backward direction.
Answer:
The pH does not increase drastically because the NaOH reacts with the _HYDRAZOIC ACID__ present in the buffer solution.
Explanation:
NaOH reacts with the hydrazoic acid in the buffer
HN3 + OH? --> H2O + N3-
If you put acid in, it will react with N3-. Here is the equation below:
N3- + H+ --> HN3
