Cylinder A - Adding 25 grams raised the water level by roughly 3.2 mL

Cylinder B - Adding 25 grams raised the water level by roughly 2.8 mL

Cylinder C - Adding 25 grams raised the water level by roughly 3.5 mL

Calculate grams/mL (density)

A. 25 g/3.2 mL = 7.8125 g/mL = Iron
B. 25 g/2.8 mL = 8.9286 g/mL = Nickel
C. 25 g/3.5 mL = 7.1429 g/mL = Zinc

Hope I helped!

Water vapor in your exhaled breath condenses in the air on a cold day.- physical change

Plants use carbon dioxide from the air to make sugar.- chemical change

Butter melts when placed in the Sun- physical change

Explanation:

What are the steps used to write ionic formulas for ionic compounds
lorasvet [3.4K]
Write the symbols for the cation and the anion: Mg and Cl. Determine the charge on the cation and anion. If the cation has a Roman numeral after it, that is the charge on that cation. Cations receive Roman numerals when they can take more than one ionicform.
