Answer:
We can simply refer to the cation in the ionic compound as magnesium. Phosphorus, Pstart text, P, end text, is a group 15 element and therefore forms 3- anions.
Explanation:
Because it is an anion, we add the suffix -ide to its name to get phosphide as the name of the ion.

How many moles of magnesium nitrate are produced when he reacts 0.34 moles of nitric acid with excess magnesium?
4. What is the molarity of a solution that contains 65g of sodium nitrate in 750? ml of solution?
Answer:
1.02 M
Explanation:
Solution contains 65g of sodium nitrate
Volume of solution = 750 ml
Now, Molar mass of sodium nitrate from online values = 84.9947 g/mol
Thus, it means 84.9947 g/mol of sodium nitrate dissolved in 1000 mL of water will be equal to 1 M molarity.
Thus;
Molarity of solution = (65/750) × (1000) × (1/84.9947) = 1.02 M
