Answer :
- B) add acid to water
Explanation :
Mixing of acid and water to make acidic solution is highly exothermic reaction and the reaction could be so vigorous that the acid may spill out of container onto the body and may produce burns .
When acid is added to water along the tip of a glass rod drop by drop , the large amount of water would absorb the energy released in the process , thus the acid won't spill .
If the water was added to acid , the acid will not be able to absorb the energy produced and the exothermic reaction would cause burns by splitting acid .
Thus the correct way to make an acidic aqueous solution or to dilute an acid is to add acid in water drop by drop along the side of a glass rod .
Explanation:
The universe (Latin: universus) is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy.
While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is currently estimated to be 93 billion light-years in diameter.
In various multiverse hypotheses, a universe is one of many causally disconnected constituent parts of a larger multiverse, which itself comprises all of space and time and its contents.
