need help with questions 1-5 please

Questions: 1. In this lab, an eudiometer tube was first filled with 10 mL 6M HCl solution and then was topped to the brim with water. Why was the entire eudiometer not filled with 6M HCI? 2. What is the purpose of re-adjusting the height of the eudiometer tube such that the solution level inside is same as outside ? 3. In this tab, 0.012-0.020 g of Magnesium strip is suggested for each run. What will happen if a student uses 0.200 g Magnesium instead? 4. Would an increase in concentration or amount of the HCI solution used in the experiment affect your results? Explain

Answer 1

In this experiment dil Hu react with Mg to give H₂ The Hu should be gas. diluted for a reasmable rate reaction . Cone. Hy will give blast reaction and can not be collected in water displacement method. of (3 Large amount + 2 gas wala level inside the tube is at the same level as the watin in the cylinder. At this point the total pressure inside the tube. is the same as atomos pheric pressure : of will produce. Mg 12hu mg Ch + H₂ this I will require large tube to collect the gas . 4 No, there is no effect of increased concentate He because the gas produced depends on ng used, my is limiting reagent (5) In this experiment we assume that the total pressure inside the tube is the same as almos atmospheric pressure , of
