Answer:
Answer. Explanation: Chlorine gas bleaches the damp litmus (red or blue). Bleaching is an oxidation process.
2.07 M is the molarity of the final solution if 45.0 ml of 6.00M HCl is added to 130 ml of O.
Explanation:
Data given:
volume of HCl, V1 = 45 ml
molarity of the HCl solution, M1 = 6 M
final volume of the HCl solution after water is added, V2 = 130 ml
final molarity M2 =?
After the dilution, the molarity of the new solution can be found by using the formula:
M1V1 = M2V2
here M1 and V1 are the molarity and volume for concentrated solution, M2 and V2 represents the diluted solution's molarity and volume.
Applying the formula after rearranging the equation, we get
M2 =
M2 =
M2 = 2.07 M
The final molarity of the HCl solution is 2.07 M

The formula of an ionic compound describes the ratio of the ions in the compound.
The percentage yield of the new production technique is 82.8%
<h3>What is the percentage yield?</h3>
Production is the procedure by which finished products are obtained form the raw materials. The production process involves the passing of raw materials through a certain procedure that involves the use of certain machines and equipment to give us the required products.
We are told in the question that there are three shifts;
Shift 1 produces 4562 grams
Shift 2 produces 5783 grams
Shift 3 produces 5247 grams
Average production from the three shifts = 4562 grams + 5783 grams + 5247 grams/3 = 5197 grams
The theoretical average yield is = 7000 grams + 7000 grams + 7000 grams/3 = 7000 grams
Now the percentage yield = actual yield/ theoretical yield * 100/1
percentage yield = 5197 grams/7000 grams * 100/1
percentage yield = 82.8%
