<h3>Answer:</h3>
Heterogeneous mixture
<h3>Explanation:</h3>
The easiest way of defining Heterogeneous mixture is that it is mixture in which the composition of components is not uniform. Also, the substances present in this mixture are visible to naked eye. In fact, the size of solutes in heterogeneous mixture is greater as compared to that the sizes of solutes in homogeneous solutions. hence in salad dressing the oil, vinegar and spices are all visible and can easily be seen by naked eye.
Answer:
Identifying whether or not an element is an ion is a very simple process. Identify the charge of the element. ... The number of electrons is equal to the atomic number minus the charge of the atom. Refer to an element with either a positive or negative charge as an ion.

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.
