Answer:
12.6 L CO2
Explanation:
Mass = 24.7 grams
Molar mass = 44.01 g/mole
Volume at STP = ?
The relationship between these quantities is given as
Number of moles = Mass / Molar mass
Number of moles = 24.7 g / 44.01 g/mole
Number of moles = 0.5612 moles
1 mol = 22.4 L
0.5612 mol = x
x = 0.5612 * 22.4
x = 12.6 L
Answer:
Option C. Silver is a catalyst in this reaction.
Explanation:
From the question given, we discovered that the addition of silver in the reaction between ethene and oxygen produces epoxyethane at a much faster rate. This simply means that silver act as a catalyst in this reaction.
A catalyst is substance that increases the rate of a reaction without itself taking part in the reaction. The catalyst creates an alternate path way by lowering the activation energy so that the reaction can proceed at a much faster rate.
Since the addition of silver makes reaction to occur at a much faster rate, it therefore means that silver act as a catalyst in the reaction.

Answer:The very bottom one is the correct answer
Explanation:
Answer:
.081 g of O2
Explanation:
4Cr + 3O2 -----> 2Cr2O3
.175 g Cr x [1 mole / 52.0 g] x [2 moles Cr2O3 / 4 moles Cr] x [152 g / 1 mole] = .256 g of Cr2O3
.175 g Cr x [1 mole / 52.0 g] x [3 moles O2 / 4 moles Cr] x [32 g / 1 mole] = .081 g of O2
