The mass of that would be formed will be 18.22 grams
Let us first look at the balanced equation of the reaction:
The mole ratio of Y to is 2:3.
Mole of 10.0 grams of Y = 10/88.9 = 0.11 moles
Mole of 10.0 grams = 10/71 = 0.14 moles
3/2 of 0.11 = 0.165. Thus, is limiting in availability.
Mole ratio of and
= 3:2
Equivalent mole of = 2/3 x 0.14 = 0.093 moles.
Mass of 0.093 moles =0.093 x 195.26 = 18.22 grams

Answer:
The volume of this sample when the temperature is changed to 150 K and the pressure is changed to 160 kPa is 52.5 mL.
Explanation:
Boyle's law says that: "The volume occupied by a certain gaseous mass at constant temperature is inversely proportional to pressure" and is expressed mathematically as:
P * V = k
where k is a constant.
Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure, by means of a constant of proportionality that is applied directly. So Charles's law is a law that mathematically says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
Gay-Lussac's law states that the pressure of a fixed volume of a gas is directly proportional to its temperature. In other words, if the volume of a certain quantity of ideal gas remains constant, the quotient between pressure and temperature remains constant:
Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:
Considering an initial state 1 and a final state 2, it is satisfied:
In this case:
- P1: 240 kPa
- V1: 70 mL
- T1: 300 K
- P2: 160 kPa
- V2: ?
- T2: 150 K
Replacing:
Solving:
V2= 52.5 mL

Sodium hydrogen carbonate has:
The + from Na+ and + from H+ makes 2+, and therefore the 2- from CO3 evens the charges to neutral.
Not to be confused with Sodium Carbonate, (Na2CO3), which lack an H, Sodium Hydrogen Carbonate is sometimes shortened to just Sodium Bicarbonate. It is used in the kitchen (cooking) as "baking soda."
Formula: NaHCO3
