Answer:
It causes erosion of the land and stones.
Explanation:
if the objects such as stones etc are present in the way of stream so the stones are eroded due to its fast flowing due to sloppy nature. If the stream is flat then it little disturb the things present in its way because of its lower speed. If more rainfall occur the streams flows in higher speed and destroy everything that comes in its way and also affected the plains.
Answer:
8.48 × 10²² atoms of Nitrogen
Explanation:
Calcium Carbonate is an ionic compound made up to Calcium (Ca²⁺) and Nitrate (NO₃⁻) ions. Also, the subscript 2 after the closed bracket after NO₃ specifies that there are two moles of NO₃⁻ in calcium nitrate compound. Hence, in total we can say that this compound contain,
1 atom of Calcium
2 atoms of Nitrogen
6 atoms of Oxygen
Therefore,
When,
1 molecule of Ca(NO₃)₂ contains = 2 atoms of Nitrogen
Then,
4.24 × 10²² molecules of Ca(NO₃)₂ will contain = X atoms of Nitrogen
Solving for X,
X = 2 atoms × 4.24 × 10²² molecule / 1 molecule
X = 8.48 × 10²² atoms of Nitrogen
