Mkey [24]

D. It is a chemical change because solubility in water of Solid A is different than the solubility in water or both Potassium Iodide and Silver Nitrate

Explanation:

From the given table which summarizes findings about the experiment, we can conclude that It is a chemical change because solubility in water of Solid A is different than the solubility in water of both Potassium Iodide and Silver Nitrate.

  • A chemical change is a form of change in which new substances are produced.
  • A physical change is one in which the states of matter changes especially the form.

Now we that two soluble substances goes to insoluble product.

  • A substance is soluble when they go into solution with a solvent of the same type.
  • This change from solubility to insolubility of a compound is a typical chemical change.
  • Other forms of changes are just physical changes.

Starting with the water in the ocean place the below steps in the correct order showing how water moves through this cycle
ruslelena [56]

Answer:

C, A, D and B

Explanation:

Water evaporates from the surface of the oceans leaving behind salts. As water vapor rises, it collects and is stored in clouds.

As water cools in the clouds, condensation occurs. Condensation is when gases turn back into liquids.

Condensation creates precipitation. Precipitation includes rain, snow, hail and sleet. The precipitation allows the water to return again to the Earth's surface.

When precipitation lands on land, the water can sink into the ground to become part of our underground water reserves, also known as groundwater.
