Return Nex 7 points When the Big Bang theory was first proposed, many scientists did not accept it because they did not believe there was enough evidence to support it. Which observation led to the Big Bang theory becoming more widely accepted by scientists? A. The universe appears to be shrinking. B. The universe appears to be expanding. C. The planets seem to move in elliptical orbits. O D. The planets seem to move backward in their orbits. ​

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
