Oxidation: a chemical change resulting form a reaction with oxygen
Endothermic:a reaction that takes in energy
Exothermic: a reaction that releases energy
Decomposition:chemical change whereby a molecule breaks down into simpler moles clues or elements

Answer: The correct statements are:
- Objects “fall” toward the center of Earth.
- Objects accelerate at a rate of 9.8 m/s each second.
- Objects are pulled by Earth more strongly than they pull on Earth.
Explanation:
The gravity of the earth is the force which attracts the object to the center of the earth. When the any object with mass falls under the action of the gravity attains the acceleration of 9.8 
.
- Objects “fall” toward the center of Earth.
- Objects accelerate at a rate of 9.8 m/s each second.
- Objects are pulled by Earth more strongly than they pull on Earth.
Answer:
Ideally, extinguish the flames with a glass watch or beaker.
Explanation:
When you cover the distillation equipment with a watch glass or beaker, you reduce the oxygen content and it is completely eliminated thanks to the fire itself that consumes it. Once there is no more oxygen the fire is extinguished and it should take no more than 2 or 3 seconds to occur this situation
It is the easiest and most careful way to extinguish the fire during the Grignard reaction
It’s c because a wave cycle is repeating patterns all over again and again
Each one is a living organism.
