Find the values of x and y in a parallelogram  

Aqueous hydrobromic acid (HBr) reacts with solid sodium hydroxide (NaOH) to produce aqueous sodium bromide NaBr and liquid water (H2O). What is the theoretical yield of water formed from the reaction of 6.5g of hydrobromic acid and 2.0g of sodium hydroxide? 

Round your answer to 2 significant figures.

Blast furnaces extra pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide:

2C(s)+O2(g)--->2CO(g)

In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:

Fe2O3(s)+3CO(g)--->2Fe(s)+3CO2(g)

Suppose the yield of the first step is 65.% and the yield of the second step is 94.%. Calculate the mass of oxygen required to make 6.0kg of iron.

Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.

Gaseous ethane (CH3CH3) reacts with gaseous oxygen gas (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). What is the theoretical yield of carbon dioxide formed from the reaction of 29.5g of ethane and 71.3g of oxygen gas? 

Round your answer to 3 significant figures.

A common way to make hydrogen gas in the laboratory is to place a metal such as zinc in
hydrochloric acid. The hydrochloric acid reacts with the metal to produce hydrogen gas, which is then collected over water. Suppose a student carries out this reaction and collects a total of 154.4 mL of gas at a pressure of 742 mmHg and a temperature of 25 oC. What mass of hydrogen gas (in mg) does the student collect?
