The motivation to abstain from adding water to concentrated acids is that, with a few acids, amid weakening, a considerable measure of warmth is discharged, by adding the corrosive to the water, the generally extensive measure of water will retain the warmth. On the off chance that you added water to concentrated corrosive when you initially beginning pouring the water, it could get sufficiently hot for the little measure of water that was filled all of a sudden bubble and splatter corrosive on you. Concentrated sulfuric corrosive is most famous for doing this, not all acids get that hot on weakening, but rather in the event that you make a propensity for continually adding the corrosive to water for every one of them, you can't turn out badly.
Explanation:
It is known that molarity is the number of moles present in a liter of solution.
Molarity = 
Also, number of moles equal mass divided by molar mass. And, molar mass of calcium is 40.07 g/mol.
No. of moles = 
= 
= 0.025 mol
Therefore, calculate the molarity as follows.
Molarity =
= 
= 0.025 M
Thus, we can conclude that molarity of 
in milk is 0.025 M.
C is correct. right now gravity holds the atmosphere so if there is no gravity then no atmospher
Because super tiny organisms called cyanobactierea (alge) they conducted photosynthesis and they us sunshine water and Carbon D to make Oxygen
