Answer:
the percentage of your solution that made up of HCI acid is 15%
Explanation:
The computation of the percentage of your solution that made up of HCI acid is given below:
Given that
There is 200g or a solution that have 0 g of hydrochloric acid (HCI)
Based on the above information
The percentage is
= 30g ÷ 200g
= 15%
Hence, the percentage of your solution that made up of HCI acid is 15%
Answer:
Q = 2997.69 J
Explanation:
Given that,
The mass of ice, m = 15.6 grams
The temperature increases from -8.76 degrees Celsius to 85.9 degrees Celsius.
The specifc heat of ice is 2.03 J/g°C
We need to find the amount of energy required. The formula for energy required is given by :
So, the required heat is equal to 2997.69 J.
Answer:
24%
Explanation:
From the question, the limiting reactant is H2S.
The reaction equation is;
2H2S + O2 → 2S + 2H2O
Number of moles of H2S reacted = 22g/34 g/mol = 0.647 moles
According to the reaction equation;
2 moles of H2S yields 2 moles of sulphur
0.647 moles of H2S yields 0.647 moles of sulphur
So;
Theoretical yield of sulphur = 0.647 moles * 32 g/mol = 20.7 g
Actual yield = 5 g
% yield = actual yield/theoretical yield * 100
% yield =5 g/20.7 g * 100
% yield = 24%
<span> The nuclear reactor powers plants to inhale heats that are needed to create/produce steam- (a gas that comes from liquid at its boiling point) The process is called fission. Fission entails the splitting on atoms in the nuclear reactor.

Water also dissolves non-ionic substances.This is because C2H5OH has a polar Oh and the bond that the water molecules like to hang around. Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. A common example is oil and water.
