PLS HELP! I CAN"T DO THIS! I AM ABOUT TO CRY COZ NO ONE WILL ANSWER TnT Chlorine is used by textile manufacturers to bleach cloth. Excess chlorine is destroyed by its reaction with sodium thiosulfate, Na 2 S 2 O 3 :
Na 2 S 2 O 3(aq) + 4Cl 2(g) + 5H 2 O (aq)  2NaHSO 4(aq) + 8HCl (aq)

1. How many grams of Na 2 S 2 O 3 are needed to react with 2.65 mol of H 2 O? (3

marks)

2. How many mol of HCl can form from 25.2 mol of Na 2 S 2 O 3 ? (2 marks)

3. How many Liters of Cl 2 are required to produce 15.7 moles of NaHSO 4 ? (2

marks)

4. How many molecules of HCl can form from 4.92 grams of H 2 O? (3 marks)

I also need the steps. Please and thank you!

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.
