Answer: 1 dissociation. 2. Hydration. 3. Dissolving.
Explanation:
Answer:
75 g
Step-by-step explanation:
<em>Step 1. </em>Calculate the molar mass of CaCO₃
Ca = 40.08
C = 12.01
3O = 3 × 16.00 = <u> 48.00
</u>
Total = 100.09 g/mol
<em>Step 2</em>. Calculate the mass of the pellet
Mass of CaCO₃ = 0.75 mol × (100.09 g/1 mol)
Mass of CaCO₃ = 75 g
The answer is D. Stars are formed from interstellar clouds because of the Law of Universal Gravitation. The interstellar clouds are termed as nebula. When other stars dies a supernova occurs then the gravity from this pushes matter into the clouds until it cannot overcome the gravitational pull and it collapses which heats matter up forming a star.
Ice floats on the surface of water 'cause <span>ice is less dense than water.
