A8 you still have one more step to take what was calculate is the number of molecules in 85g of ammonia. B6 is okay catalase is the enzyme in the live that works on hydrogen peroxide Wow what a journey thank you sir for your work.

[@THEDMSONLINESCHOOL]

It was done, just check again, you will find that after finding 5mol, then the number of atoms was calculated using avogadro's law where one mol is equal 6.02e23 particles. So 5mol was multiplied with avogadro's constant and the answer was 3.0e24 atoms. Thanks for your feedback. We appreciate it. ♥️♥️

A9 If 40tons of NaOH is reacting with 98tons of H2SO4, then X tons of NaOH will react with 490tons. When we cross multiply it will be 490 x 40 ÷ 98 = 200 tons. Kindly confirm Sir. You are the best and I enjoy your teaching you are making education easy and as well as the exam. Thank God bless you!👏👏
