Answer: the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure
Explanation:
The chemical formula for calcium hydroxide is Ca(OH)₂ and that of nitric acid is HNO₃. By these chemical formula it can be deduced that the number of equivalents per mole of Ca(OH)₂ is 2 because of 2 OH⁻ and for HNO₃ is 1 because of H⁺.
For the neutralization reaction, the number of equivalents should be equal.
V₁n₁ = V₂n₂
Substituting the known values and with the incorporation of the concept above,
(V₁)(0.0250 mol/L)(2 equivalents/mol) = (33.50 mL)(0.020 mol/L)(1 equivalent/mol)
V₁ = 13.4 mL
Hence, the volume of calcium hydroxide needed is approximately equal to 13.4 mL.

Beryllium because it's a metal which is in nature usually found as cations held together by delocalized electrons and there is also a trend on the periodic table which suggests that ionization energy increases from left to right across a period and decreases from top to bottom down a group
Answer:
4. They are a renewable resource, they reproduce. any animal and plant has some form of reproducing. A couple ways they could become nonrenewable resources are if they are exterminated through disease, habitat destruction, introduction of a harmful species.
5. Generally the discussion of overconsumption parallels that of overpopulation; that is the more people, the more consumption of raw materials to sustain their live
6. Recycling uses less energy than making a new product from scratch – even when you take account of all the related costs, like transport and wages. Mining, quarrying, logging, processing and transporting raw materials to prepare them for use in industry takes a great deal of energy.
