I have attached my work for 1-3. I would like to see if you can get 4 and 5 on your own. but, if you are struggling/copnfused please let me know in the comments! :)
Answer:
168.0 g
Explanation:
First thing, write a balanced chemical equation:
n(H2SO4) = concentration * volume
= 1.0 M * 2.0 L
= 2.0 mol
According to the balanced equation, 1 mol of acid requires 2 mol of sodium bicarbonate. This means that 2 mol of acid requires 2 mol of sodium bicarbonate. What mass of sodium bicarbonate is this?
mass (NaHCO3) = number of moles * molar mass
= 2.0 mol * 84.0065 g/mol
= 168.0 g
A lot of things in life involve chemistry. Let's start from the most obvious one - cooking.
While you are cooking, you need to mix ingredients and create homogeneous and heterogeneous mixtures, which is where chemistry is applied. Also, all of these ingredients change their physical and chemical state, which is also what chemistry studies.
