Answer:
C. Carbon monoxide
This is my answer tell me if wrong
Answer:
Explanation:
2 H₂S(g) +S0₂(g) = 3 S(s) + 2H₂0(g)
2 x 34 g 64 g 3 x 32 g
68 g of H₂S reacts with 64 g of S0₂
3.89 g of H₂S reacts with 64 x 3 .89 / 68 g of S0₂
3.89 g of H₂S reacts with 3.66 g of S0₂
S0₂ given is 4.11 g , so it is in excess .
Hence H₂S is limiting reagent .
68 g of H₂S reacts with S0₂ to give 96 g of Sulphur
3.89 g of H₂S reacts with S0₂ to give 96 x 3.89 / 68 g of Sulphur
3.89 g of H₂S reacts with S0₂ to give 96 x 3.89 / 68 g of Sulphur
5.49 g of Sulphur is produced .
Actual yield is 4.89
percentage yield = 4.89 x 100 / 5.49
= 89 % .
Answer:
The new volumen of the solution is 500 ml.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
V2= (C1xV1)/C2
V2= (400 ml x 2,5 M)/2,0M
<em>V2= 500 ml</em>
Answer:
0.89821 atm
Explanation:
Psi and atm are units of pressure.
Psi stands for pound force per square inch.
While atm stands for atmosphere.
In order to convert the psi to atm we would divide the given value 14.696.
Given value = 13.2 psi
In atm:
13.2 / 14.696 = 0.89821 atm
Answer:
last one is the correct and most suitable option.
Hope it helps!!!
