New moon is the phase in which it cannot be seen
Answer:
Option b is correct.
Explanation:
When 
is dissolved in water, 
and 
are formed.
As is an weak base and is a strong acid, the resulting solution will be acidic in nature.
if K_b value is known, then pH of the solution can also be determined which will support prediction.
However, acidic and basic nature of the solution can be predicted without K_b value also.
So, among the given option, (b) is correct.
Answer:
nuclear envelope, nuclear la Nina, nucleolus, chromosomes, and nucleoplasm. Hope this helped?
For each ionic compound formula, identify the main group to group 17 (VIIA).
Group17 (VIIA) is the primary group to which X belongs in each ionic combination with the formula CaX2. X is undoubtedly an electron acceptor. It is capable of taking an electron. We determine that X must be in the oxidation state -1 by looking at the chemical formula. The neutral ionic compound's total number of oxidation states is zero. Since calcium has an oxidation state of +2, we must identify the element that contains an anion with an oxidation state of -1. The halogens have a strong propensity to pick up an electron and create an anion. X belongs to group17 (VIIA) as a result.
