Answer;
-H2O, water
Explanation;
-Hydrocarbons undergoes combustion to form water and carbon dioxide. Propane (C3H8) is a hydrocarbon that belongs to the homologous series alkanes. Thus, propane will undergo combustion to form 3 molecules of carbon dioxide and 4 molecules of water.
Thus the complete equation will be;
-C₃H₈ + 5O₂ = 3CO₂ + 4H₂O
Answer:
2.41 g of NaCl is needed
Explanation:
Molarity of solution = (Number of moles of solute)/(Volume of solution in Litre)
Here sodium chloride (NaCl) is solute in saline solution
275 mL = 0.275 L
So, number of moles of NaCl in 275 mL saline solution =
Molar mass of NaCl = 58.44 g/mol
Number of moles = (mass)/(molar mass)
So, mass of 0.04125 moles of NaCl =
So, 2.41 g of NaCl is needed

Answer:
The molar mass of the gas is 90.4g/mol
Explanation:
To solve this question we have to use the equation:
d = PM / RT
<em>Where d is density of the gas = 2.29g/L</em>
<em>P is pressure = 0.75atm</em>
<em>M is molar mass of the gas = ??</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>T is absolute temperature = 88°C + 273.15 = 361.15K</em>
<em />
Solving for M:
dRT / P = M
2.29L*0.082atmL/molK*361.15K / 0.75atm = M
90.4g/mol = M
The molar mass of the gas is 90.4g/mol
