Answer:
atomic mass of X is 48.0 amu
Explanation:
Let y be the atomic mass of X
Molar mass of O_2 is = 2×16 = 32 g / mol
X + O2 -----> XO_2
According to the equation ,
y g of X reacts with 32 g of O_2
24 g of X reacts with Z g of O_2
Z = ( 32×24) / y
But given that 24.0 g of X exactly reacts with 16.0 g of O_2
So Z = 16.0
⇒ (32×24) / y = 16.0
⇒ y = (32×24) / 16
y= 48.0
So atomic mass of X is 48.0 amu
<span>2 H</span>₂<span> + O</span>₂<span> = 2 H</span>₂<span>O
4 g H</span>₂ ------------ 32 g O₂----------- 36 g H₂O
<span> 8 g H</span>₂ ------------ 64 g O₂------------ ? g H₂O
<span>
Mass of H</span>₂O :
<span>
64 * 36 / 32 =
2304 / 32 = 72 g of H</span>₂O

14,400 gallons of water can be filtered by the new water filter invented by the company.
It is given that the filter can process 10 gallons of water per minute.
So In an hour:
10 gallons per minute x 60 minutes = 600 gallons in 1 hour.
And in a day:
24 hours x 600 gallons per hour = 14,400 gallons in 24 hours.
Hence, 14,400 gallons of water can be filtered.

<span>Oxygen obey the octet rule when reacting to form compounds by adding 2 electrons. Its means the charge on Oxygen is -2.
</span>It has oxidation state −1 is found in a few compounds such as <span>peroxides.</span>
Answer:
9.6 moles O2
Explanation:
I'll assume it is 345 grams, not gratis, of water. Hydrogen's molar mass is 1.01, not 101.
The molar mass of water is 18.0 grams/mole.
Therefore: (345g)/(18.0 g/mole) = 19.17 or 19.2 moles water (3 sig figs).
The balanced equation states that: 2H20 ⇒ 2H2 +02
It promises that we'll get 1 mole of oxygen for every 2 moles of H2O, a molar ratio of 1/2.
get (1 mole O2/2 moles H2O)*(19.2 moles H2O) or 9.6 moles O2
