Hello so I am under a lot of stress and pressure. Please help me with my chemistry homework quickly please I am on the verge of crying

Question

1. 3 Cu + 8HNO3 --> 3 Cu(NO3)2   + 2 NO + 4 H2O

In the above equation how many moles of water can be made when 25 moles of HNO3 are consumed?

1. Sodium chlorate decomposes into sodium chloride and oxygen gas as seen in the equation below. 

­­2NaClO3­ --> 2NaCl +3O2

How many moles of NaClO3­ were needed to produce 44 moles of O2? Round your answer to the nearest whole number.

please solve please

Answer 1

(1) 8 moles of HNO3 gives 4 moles of water

1 mole of HNO3 gives (4/8) moles of water

25 moles of HNO3 gives 25 x (4/8) moles of water

3 moles of O2 needs 2 moles NaClO3

1 mole needs (2/3) moles

44 moles needs 44 x (2/3) moles
