The chemical equation below shows that hydrogen and oxygen chemically react to form water. Which of these is true?

A.

Water is a pure substance and has the same properties as oxygen.

B.

Water is a pure substance and has the same properties as hydrogen.

C.

Hydrogen and oxygen are pure substances that have identical properties to each other.

D.

Hydrogen, oxygen, and water are pure substances that each have different properties.

D

Explanation:

Hydrogen, oxygen, and water are pure substances that each have different properties.

Although the 3 of them are pure substances, but they nonetheless have different properties. These properties could either be their physical properties, or their chemical properties. This is particularly so because since Oxygen and Hydrogen the major components in water have different properties, it is only right if their product, water, has different properties also.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

pretty sure it's false
