Answer:Explanation:
In compounds, all other atoms are assigned an oxidation number so that the sum of the oxidation numbers on all the atoms in the species equals the charge on the species.

126 grams of H2O is formed.
Explanation:
Data given:
volume of the gas = 88 Liters
pressure = 720 mm Hg or 0.947 atm
temperature T = 22 Degrees or 295.15 K
R = 0.08021 atm L/mole K
n =?
The formula is used is of ideal gas law to know the number of moles of CH4 undergoing combustion.
PV = nRT
n = 
putting the values in the equation
= 0.947 X 88/ 0.08021 X 295.15
n = 3.5 moles
balanced reaction for combustion of methane
CH4 + O2 ⇒ CO2 + 2H20
1 mole of CH4 undergoes combustion to form 2 moles of water
3.5 moles will give x moles of water
2/1 = x/3.5
x = 7 moles of water (atomic mass of water = 18 gram/mole)
mass = atomic mass x number of moles
mass = 18 x 7
=126 grams of water is formed.
Answer:
Fossil fuels
Explanation:
Fossil fuels — natural gas, coal, and petroleum, and — provide most (63 %) of the energy consumed in the United States
The breakdown in 2019 was
Natural gas 38 %
Coal 24 %
Petroleum 1 %
Answer:
Nitrogen monoxide and oxygen are called the reactants
Explanation:
Step 1: Given data
Nitrogen monoxide = NO
Oxygen = O2
Step 2: Balanced equation
2NO + O2 → 2NO2
This means that 2 moles of NO will be consumed and and 1 mole of O2 to produce 2 moles of NO2
This means NO2 is the prodcut that is produced.
NO +O2 react with eachother, to form NO2
This means nitrogen monoxide (NO) and Oxygen (O2) are called the reactants.
