1.when citric acid reacts with baking soda, a salt, water and a gas are produced. what is the name of the gas?
2. when vinegar, an acid, is mixed with baking soda, a base, the reaction is similar to the reaction of alka-seltzer and water; a salt, water and carbon dioxide are produced. in two or more complete sentences, describe how your knowledge of balancing chemical equations can you to determine the missing compound.
nahco3 + hc2h3o2 ⟶ + h2o + co2

1) Carbon dioxide is the name of the gas.

2) The missing compound is

Step-by-step explanation:

1)When ever an acid reacts with baking soda brisk effervescence of carbon dioxide gas are released.

So, when citric acid reacts with baking soda it gives salt of sodium citrate , water and carbon dioxide gas.

2)

According to law of conservation of mass:

Number of atoms on reactant sides are equal to the number of atoms on product side.

Number of atoms of an element on left hand side is equal to the number of atoms of that same element on the right hand side.

Number of hydrogen atom on reactant side = 5

Number of hydrogen atom on product side = 2+ x

5 = 2+x

x = 3

Number of carbon atom on reactant side = 3

Number of carbon atom on product side = 1 + y

3 = 1 + y

y = 2

Number of oxygen atom on reactant side = 5

Number of oxygen atom on product side = z + 3

5 = z + 3

x = 2

Number of sodium atom on reactant side = 1

Number of oxygen atom on product side = a

1 = a

The missing compound is
