Explanation:
1) One piece of science equipment that you might not have been introduced to is the graduated cylinder. measure volume of a liquid.
2) Although you need to be careful when using a Bunsen burner, I think it is one of the most interesting lab tools to use. A Bunsen burner is a heat source used to raise the temperature.
Answer:
10.24 ×10²³ molecules
Explanation:
Given data:
Mass of COCl₂ = 218.4 g
Number of molecules = ?
Solution:
Number of moles of COCl₂:
Number of moles = mass/molar mass
Number of moles = 218.4 g/ 129.84 g/mol
Number of moles = 1.7 mol
1 mole contain 6.022×10²³ molecules.
1.7 mol × 6.022×10²³ molecules / 1mol
10.24 ×10²³ molecules
Explanation:
Carbon black sphere
Nitrogen blue sphere
Chlorine green sphere
Hydrogen white sphere
Reactants:
three molecules that contain one black sphere and four white spheres
3CH₄
three molecules that contain two blue spheres and four green spheres:
3N₂Cl₄
Products:
three molecules that contain one black sphere and four green spheres:
3CCl₄
three molecules that contain two blue spheres:
3N₂
six molecules that contain two white spheres
6H₂
The reaction proper:
3CH₄ + 3N₂Cl₄ → 3CCl₄ + 3N₂ + 6H₂
