Answer:
Actual yield = 1.825 g
Explanation:
Given data:
Theoretical yield = 1.98 g
Percent yield = 92.1687%
Actual yield = ?
Solution:
Formula:
Percent yield = actual yield / theoretical yield × 100
Now we will put the values in formula:
92.1687 = actual yield / 1.98 g × 100
92.1687 / 100 = actual yield / 1.98 g
0.921687 = actual yield / 1.98 g
0.921687 × 1.98 g = actual yield
Actual yield = 1.825 g

Answer:
Bromine is a very reactive element. While it is less reactive than fluorine or chlorine, it is more reactive than iodine. It reacts with many metals, sometimes very vigorously. For instance, with potassium, it reacts explosively.
Explanation:
A displacement reaction will occur from the system given above. The chlorine molecules will displace the bromide ions in the solution of sodium bromide. The reaction will yield to sodium chloride and bromine. The reaction will be:
2NaBr + Cl2 = 2NaCl + Br2
Answer:
0.0345kg is the mass of 25L of the sample
Explanation:
Hydrophosphoric acid, H₃P = Phosphine has a density of 1.38g/L.
To solve this question we need to convert the volume of the gas to mass in grams as first and then to kilograms as follows:
<em>Mass in grams:</em>
25L * (1.38g / L) = 34.5g
<em>Mass in kilograms:</em>
34.5g * (1kg / 1000g) = 0.0345kg is the mass of 25L of the sample
