Sodium bicarbonate is sometimes used to neutralize acid spills. If 2.0 L of 1.0 M H2SO4 is spilled, what mass of sodium bicarbon
UkoKoshka [18]

Answer:

168.0 g

Explanation:

First thing, write a balanced chemical equation:

H_{2}SO_{4}+ 2NaHCO_{3}  ----> Na_{2}SO_{4} + 2H_{2}O+2CO_{2}

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

What are some things in life that involve chemistry and how does chemistry apply?
Nady [450]
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.
