Answer:15 +18
Explanation:15 fuel +18 oxygen + 33 cd
Answer:
0.67 L
Explanation:
Given data:
Volume of carbon dioxide = ?
Mass of nitroglycerine = 2.5 g
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Solution:
Chemical equation:
4C₃H₅N₃O₉ → 12CO₂ + 10 H₂O + 6N₂ + O₂
Number of moles of nitroglycerine:
Number of moles = mass/ molar mass
Number of moles = 2.4 g/ 227.1 g/mol
Number of moles = 0.01 mol
Now we will compare the moles of nitroglycerine and carbon dioxide from balance chemical equation.
C₃H₅N₃O₉ : CO₂
4 : 12
0.01 : 12/4×0.01 = 0.03 mol
Volume of CO₂:
PV = nRT
V = nRT/P
V = 0.03 mol× 0.0821 atm.L/mol.K× 273.15 K / 1 atm
V = 0.67 L
Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. Nuclear energy can be used to make electricity.
Answer:
The number of atoms in the reactants equals the number of atoms in the products.
Explanation:
In every chemical reaction equation there are two sides; the reactants sides and the products side. The reactants side shows the species that combine to form the products. On both sides of the reaction equation, chemical species are found to be composed of atoms.
The major principle in balancing of chemical reaction equations is that the number of atoms of each element in the reactants side must be equal to the number of atoms of the same element on the products side. Once this condition is achieved, we can now say that the chemical equation is balanced.
