How many moles of H2O are produced when 25.6. grams of oxygen are used? Thank you

1.6mole of H2O

Explanation:

First let us generate a balanced equation for the reaction. This is illustrated below:

2H2 + O2 —> 2H2O

Molar Mass of O2 = 2 x 16 = 32g/mol.

Mass of O2 = 25.6g

Number of mole of O2 = Mass /Molar Mass

Number of mole of O2 = 25.6/32

Number of mole O2 = 0.8mol

From the equation,

1mole of O2 produced 2moles H2O.

Therefore, 0.8mol of O2 will produce = 0.8 x 2 = 1.6mole of H2O

s too much pool water may lead to chlorine poisoning. the concentration of chlorine in public drinking water is extremely low and not harmful to human health. sooo yeahh

explanation:

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
