Answer:
All alkali and alkaline earth metals dissolves in water to form alkaline solutions.
Explanation:
The alkali metals are found in group one of the periodic table while the alkaline earth metals are found in group 2. These two groups of elements are quite reactive and they react very well with air and water. All the elements in the two groups react with water to give rise to alkaline solutions; solutions whose pH range from 8 to 14.
I think the correct answer would be the number of atoms in a carbon isotope. This is because before mole was created atomic mass unit was first used to measure molecular stuff. Then, later on mole was created which is based on carbon-12 isotope.
The mass of carbon needed is 56g to get it to stop
to be honest I'm trying to give an educated guess hope I've helped
Substitution because you switch some of the other atoms when you get to the other side
The rate of evaporation is equal to rate of condensation in equilibrium......It means the evaporation rate becomes constant.....And thus equilibrium attained !!!
