Magnese sulfide would be MnS
Answer:
<h2>Volume = 57.34 dm³</h2>
Explanation:
The volume of a gas can be found by using the formula
V = n × V(dm³)
where
n is the number of miles
V is the volume
V(dm³) is the volume of 1 mole of a gas at STP which is 22.4 dm³
From the question
n = 2.56
The volume is
V = 2.56 × 22.4
We have the final answer as
<h3>Volume = 57.34 dm³</h3>
Hope this helps you
Answer:
2. B. 5:3
3. C. mass and atoms only.
Explanation:
Hello there!
2. In this case, according to the given balanced chemical reaction it is possible to realize that the mole ratio of oxygen to carbon dioxide is B. 5:3 since there is a 5 on O2 and a 3 on CO2.
3. In this case, according to the law of conservation of mass it is possible to realize that matter cannot be created nor destroyed; for that reason both mass and atoms must remain unchanged as the reaction takes place; therefore the answer is C. mass and atoms only.
Best regards!
