Answer:
Two electrons each!
Explanation:
The question pretty much requires us to find the oxidation number of Zinc in the compound.
Zn3P2
Following oxidation number rules;
O.N of Zn3P2 = 0
.Since phosphorus has valence of 5, it needs three more electrons to achieve its octet state. Hence;
Oxidation number of P = -3
Let oxidation number of Zn = x
We have;
3x + 2 (-3) = 0
3x + (-6) = 0
3x = 6
x = 6/3 = 2
This means each zn electrons lost 2 electrons.
D. impermeable rocks
Explanation:
Impermeable rocks is the factor among the give choices that will increase the amount of water runoff on the surface.
Surface run-off is liquid water that flows and moves on the earth surface.
- An impermeable rock is a rock that lacks porosity and permeability.
- Porosity is the amount or percentage of void spaces in rock.
- Permeability is the inter-connectivity of the pores.
- When a rock is impermeable, it will not allow water to infiltrate.
