Molar mass ( CuSO₄) = 159.609 g/mol
159.609 g ----------------- 6.02 x 10²³ molecules
? g ------------------ 3.36 x 10²³ molecules
mass = ( 3.36 x10²³) x 159.609 / 6.02 x 10²³
mass = 5.36 x 10²⁴ / 6.02 x 10²³
mass = 8.90 g
hope this helps!
) adding phosphoric acid, said phosphoric acid reacting with said calcium carbonate to release gaseous carbon dioxide bubbles, and said water providing water of hydration to said plaster of Paris to form gypsum that sets around said carbon dioxide bubbles thereby forming said foamed plaster.
I want to see how the temperature of water affects the speed of rusting. What is the Independent Variable?
The Independent Variable is the temperature of water.
Answer:
salt water, soda, orange juice, coffee
Explanation:
Let's see
- ∆S refers to the total change in entropy of system.
Graphite was in solid state and oxygen was in gaseous state.
When they synthesized they converted to gaseous state
- So randomness of particles increases
- So entropy also increases
∆S=+ve
