The one with 20 coils as it can generate more electricity.
Answer:
4.2 Liters (2 sig-figs)
Explanation:
Apply Boyles Law ... P₁V₁ = P₂V₂
P₁ = 712 Torr P₂ = 3560 Torr
V₁ = 21.0L V₂ = ?
P₁V₁ = P₂V₂ => V₂ = P₁V₁/P₂ = (712Torr)(21.0L)/(3560Torr) = 4.2 Liters (2 sig-figs)
Answer:
The difference between a cation and an anion is the net electrical charge of the ion. Ions are atoms or molecules which have gained or lost one or more valencee electron giving the ion a net positive or negative charge. Cations are ions with a net positive charge.
Explanation:
Answer:
20 g of CO₂ have 5.47x10²³ oxygen atoms
Explanation:
1 mol of CO₂ has 1 mol of C and 2 moles of O.
Mass / Molar mass = Moles
20 g / 44 g/m = 0.454 moles
In 1 mol we find 2 moles of O
In 0.454 moles of CO₂, we will find ( 0.454 .2) = 0.909 moles
1 mol has _____ 6.02x10²³ atoms
0.909 moles have (0.909 . 6.02x10²³) = 5.47x10²³ atoms
