Answer:

The volume would be 6,4 L

Explanation:

We use the Boyle Mariotte formula, according to which for a certain mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1 = P2xV2

V2= (P1xV1)/P2= (3,2 atm x 2, 00 L)/1,00 atm= 6,4 L

How many neutrinos does an element have if it's atomic number is 47 and it's mass number is 169
Stells [14]

This element would have 122 neutrons.

Atomic mass is the accumulation of neutrons and protons.

169 - 47 = 122.

Therefore, there are 122 neutrons.

The combustion of 0.1240 kg of propane in the presence of excess oxygen produces 0.3110 kg of carbon dioxide. What is the limiti
nadezda [96]

Answer:

The limiting reactant is the propane gas, C₃H₈ while the percentage yield is 83.77%

Explanation:

Here we have

Propane gas with molecular formula C₃H₈, molar mass  = 44.1 g/mol combining with O₂ as follows

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Therefore, 1 mole of C₃H₈  combines with 5 moles of O₂ to produce 3 moles CO₂ and 4 moles of H₂O

Mass of propane = 0.1240 kg = 124.0 g

Number of moles of propane = mass of propane/(molar mass of propane)

The number of moles of propane = 124/44.1 = 2.812 moles

The molar mass of CO₂ = 44.01 g/mol

Mass of CO₂ = 0.3110 kg = 311.0 g

Therefore, number of moles of CO₂ = mass of CO₂/(molar mass of CO₂)

The number of moles of CO₂ = 311.0 kg/ 44.01 g/mol = 7.067 moles

Therefore, since 1 mole of propane produces 3 moles of CO₂, 2.812 moles of propane will produce 3 × 2.812 moles or 8.44 moles of CO₂

Therefore;

The limiting reactant is the propane gas, C₃H₈, since the oxygen is in excess

Hence

The \ percentage \ yield = \frac{Actual \, yield}{Theoretical \, yield} \times 100 = \frac{7.067}{8.44} \times 100 = 83.77 \%

The percentage yield = 83.77%.

Two molecules of hydrogen react with one molecule of oxygen to produce two
Alex787 [66]
You would need to utilize Mole ratios found in the adjusted condition; 
for each mole of hydrogen utilized, 2 moles of HCl are delivered. 
Thusly: 
10 mol H2 x 2 mol HCl/1 mol H2 = 20 mol HCL. 
For the second question: 
you would need to change over 2.0x10^23 particles of Oxygen to moles of oxygen, utilizing Avogadro's number: 
2.0x10^23 particles oxygen x 1 mol oxygen/6.022x10^23 atoms oxygen = 0.33 mol Oxygen 
utilizing mole proportions once more: 
 0.66 mol H2O = 2 mol H2O/1 mol Oxygen x 0.33 mol Oxygen 
45.0 mol H2O  = 2 mol H2O/1 mol Oxygen x 22.5 mol Oxygen 
fundamentally to answer stoichiometry, you should take a gander at the adjusted condition to make sense of the mole proportions between components/mixes, and utilizing mole proportions you can change over from moles of one component/compound to moles of another component/compound
