A student is conducting an experiment to see how a watering schedule affects the growth of grass. he conducts the experiment two times. his data different each tim, and he comes to two different conclusions. what should he do next? A. Forget about the entire investigation
B. Get different kinds of plants and start over
C. Repeat the experiment carefully one or more times
D. Change the results so that they match

C. Water falls from the sky as rain. The water then flows downhill.

Explanation:

Water cycle can be defined as a process which typically involves the circulation (movement) of water between the Earth's atmosphere, land and ocean under various atmospheric conditions such as precipitation (rain and snow), transpiration, condensation and evaporation.

Basically, the movement of the water starts from the sky due to the condensation of water vapor to form clouds and later result to rainfall. Consequently, the rain water are either soaked by the soil or are made to flow down the hill.

The statement which best describes a way in which water moves in the water cycle is that, water falls from the sky as rain. The water then flows downhill or seeps into the ground.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
