Find the number of moles of water that can be formed if you have 154 mol of hydrogen gas and 72 mol of oxygen gas.

77

Explanation:

H2O needs 2 hydrogens and you have 154 so 154/2 is 77

thats the most you can do

The answer is 144 mol.

Explanation:

"72 mol of oxygen will form only 144 mol of water, and 10 mol of hydrogen remain in excess, so the limiting reactant is oxygen and hydrogen is in excess."

explanation:

since this is put under health, i would define "ethical (medical) behavior" the way the oath for doctors is recited.   "first do no harm."

but the term in general means when given a choice between right and wrong, we should always choose right. if we do, then we are practicing ethical behavior.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
