Answer:

Ca - 63.546 g

2N - 28.014 g

2O3 - 96 g

Ca(NO3)2 = 187.56 g

187.56 g x 0.75 mol = 140.67 g

vazorg [7]
<span>The answer is C. The volume decreases. A scuba diver at the surface of the sea takes a deep breath and fills her lungs with 6 liters of air. The pressure in her lungs is 1 atm. She then dives down ten meters, without inhaling or exhaling, until the pressure of the air in her lungs is 2 atm. According to Boyle’s law,  the air in her lungs decreases as she dives down.  </span>Boyle's Law<span> is the gas </span>law which states that in a closed space, pressure and volume are inversely related. As pressure increases, volume decreases, and vice versa.

Law of action-reaction
anzhelika [568]

Answer:

Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.

olga nikolaevna [1]

Grady is doing an experiment about the solubility of sugar. He puts 100 milliliters of water in each of three beakers. He leaves the first beaker at room temperature, heats the second beaker to 60°C, and heats the third beaker until the water boils at 100°C. The variable Grady change on  purpose in the experiment is the temperature of water in each beaker .

Variables in the experiment is the any factor that can exist in different types or amount. There are three types of variables: independent variable , dependent variable , controlled variable. The independent variable is the variable you changed in the experiment. dependent variable is that changes because of independent variable. the controlled variable is the constant one.

Thus, Grady is doing an experiment about the solubility of sugar. He puts 100 milliliters of water in each of three beakers. He leaves the first beaker at room temperature, heats the second beaker to 60°C, and heats the third beaker until the water boils at 100°C. The variable Grady change on  purpose in the experiment is the temperature of water in each beaker .
