Given:
2.5 mol O2
Required:
Grams of water
Solution:
2H2 + O2 -> 2H2O
Moles of H2O = (2.5 mol O2)(2moles H2O/1 mole O2) = 5 moles H2O
Molar mass of H2O = 18.02 g/mol
Mass of H2O = (5 moles H2O)( 18.02g/mol)
Mass of H2O =90.1g H2O
gasoline
carbon
glucose
Answer: The correct answer is carbon.
Explanation:
Combustion reaction is defined as the reaction in which a hydrocarbon burns in oxygen or reacts with oxygen gas to produce carbon dioxide and water molecule.
Fossil fuels are defined as the hydrocarbons which mainly contains coal, fuel oil, natural gas etc..
When fossil fuels are burned in air, it mainly releases carbon dioxide, sulfur dioxide, methane, nitrous oxide etc..
The major component released during the combustion of fossil fuels is carbon.
Hence, the correct answer is carbon.
c. neon atoms.
d. magnesium and chlorine atoms.
Answer:
D
Explanation:
Answer:
0.64 J/g-K
Explanation:
Solving this question relies on the relization that both blocks receive the same amount of energy but of course their temperature cannot rise by the same amount even if you had the same mass of both because they have different specific heat capacities.
amount of energy received by block 1 = amount of energy received by block 2
specific heat of block 1 * ΔT of block 1 = specific of block 2 * ΔT of block 2
C * 3 = 0.24 * 8
C = 0.64 J/g-K
