When hot lava reaches seawater, the salts in the water react with steam to form gaseous hydrochloric acid. you are given an unbalanced chemical equation for one such reaction and the volume of hcl(g) produced. explain how you would find the mass of solid sea salt needed to produce the given gas volume.

First, I would balance the chemical equation.

I would convert the volume of HCl to mol HCl by dividing by the molar volume.

Next, I would use the balanced equation to find out how many moles of the salt are needed to produce the moles of HCl.

Finally, I would multiply by the molar mass of the salt to convert moles to mass.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
