Answer:

a. Combustion.

b. m_C=3.057gC

c. m_H=3.67gH

Explanation:

Hello.

a. In this case, given the reaction by which propane is converted into carbon dioxide and water:

C_3H_8+5O_2 \rightarrow 3CO_2+4H_2O

It is known as a combustion reaction since it is about a fuel (here propane) which is burnt by the oxygen contained in the air (21%).

b. Since the carbon dioxide contains all the carbon in the products based on the law of conservation of mass, the yielded grams are computed via a mole mass relationship:

m_C=11.21gCO_2*\frac{12gC}{44gCO_2}=3.057gC

Since 44 grams of carbon dioxide contain 12 grams of carbon.

c. As well as b., all the hydrogen is  given off in form of water, thus, the required mass turns out:

m_H=33.0gH_2O*\frac{2gH}{18gH_2O}=3.67gH

Since 18 grams of water contain 2 grams of hydrogen.

Best regards.

A chemist prepares a solution of aluminum sulfite by measuring out 109 umol of aluminum sulfite into a 350 mL volumetric flask a
Lelu [443]

Answer:

0.311 mmol/L

Explanation:

109  μmol = 109*10^(-6) mol

109*10^(-6) mol = 109*10^(-6) mol*(10^3 mmol/1mol) = 109*10^(-3) mmol =

=0.109 mmol

350 mL = 0.350 L

0.109 mmol/0.350 L = 0.311 mmol/L
