Answer:

12.5%

Explanation:

32/16 = 2 moles of oxygen

2 x 18.01 x 2/1 = 72.04 g of H2O

9/72.04 x 100 = 12.5%

balanced equation: 2H2 + O2 → 2H2O

PLEASE HELP ME, 20 POINTS

Marrrta [24]

Explanations:

Question 1: Lithium in 20.00+ g is C. or D., but 25.00+ g is D. which means this is the correct option.

I am unsure of Question 2. I don't think it is mole though.

Question 3: Boron in 25.00-30.00 g is B. or D., but 25.00 g would be C.

Question 4: 2.393 x 1024 atoms of Oxygen is 63.58 mole O. I don't know for sure, but I think this is correct.

I am NOT professional. There is a chance I am incorrect. Please reply to me if I've made a mistake.

Why are nanowhiskers used to repel stains on fabrics??

Nanowhiskers or cellulose nanofibers are nano-structured cellulose produced by bacteria. They have relatively high crystallinity and ability to form a dense network held together by inter-fibrillar bonds that has the tendency to act as a barrier through their film-forming properties to which they can repel stains on fabric.
