<u>Answer:</u> The mass of oxygen reacted is
<u>Explanation:</u>
We are given:
Moles of propane = 9.98 mol
For the given chemical equation:
By Stoichiometry of the reaction:
1 mole of propane reacts with 5 moles of oxygen.
So, 9.98 moles of propane will react with = of oxygen.
To calculate the mass of carbon dioxide, we use the equation:
Moles of oxygen = 49.9 moles
Molar mass of oxygen gas = 32 g/mol
Putting values in above equation:
Hence, the mass of oxygen reacted is
100.0g x 4.184J/g/°C x 78°C ΔT = 32,645.2 Joules.
Answer:0.125 moles of CaCl2
Option D 0.13moles
Explanation:
Molarity= number of moles/ volume of solution
0.25M×.5 = number of moles
0.125 moles

Explanation:
Answer:
0.174kg of Ore are required
Explanation:
The ore of 37.3% in nickel by mass means that <em>in 100g of ore there are 37.3g of nickel. </em>As we need to obtain 65g of nickel we can convert this mass to mass of ore using the conversion factor (100g Ore / 37.3g Nickel) as follows:
65g of nickel * (100g Ore / 37.3g Nickel) = 174g of Ore are needed to have 65.0g of nickel. In kilograms:
174g Ore * (1kg / 1000g) =
<h3>0.174kg of Ore are required</h3>
