As plants take out carbon dioxide from the atmosphere which they use for photosynthesis (making food). So as the number of plants increases carbon dioxide in the air decreases.
Answer:
SO4 (aq) + Sr (aq) >> SrSO4 (s)
Explanation:
K+1 SO4-2 + Sr +2 I2- >> sK +1
(you dont separate and write down the ions for Sr SO4 because its a solid)
Cancel out the same ions from both sides and write down what your left with.
Answer:
D
Explanation:
All explain physical no chemical examples were given
Answer:
The correct answer is :'The gravitational force between two objects is related mathematically to their mass and the distance between them'.
Explanation:
A scientific law is a statement which explains physical phenomena and has been tested multiple times through the correct scientific methods and experimentation. It will give same results and observations after each conduct.
A scientific law comes into picture after the acceptance of a theory which explains or exposes the reason behind any physical phenomena occurrence.
So the best example of scientific law:
The gravitational force between two objects is related mathematically to their mass and the distance between them.
