2. This question has two parts. First, answer
Part A. Then, answer Part B. Part A
In Passage 2, what theme is suggested by Graham’s situation?
D People will do whatever is necessary to keep what is important to them.
Part B
Which quotation helps develop the theme in Part A?
D “Graham turned to the old man and asked, ‘How are we going to find it?’” (paragraph 25)

Answer:
Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge. Each calcium atom will be closer to the delocalized electrons. Thus, the bonds in calcium will be stronger than that in potassium.
Explanation:
Explanation:
As we know that density is the amount of mass present in a liter of solution.
Mathematically, density =
As it is given that density of water is 1 g/ml and volume is 175 mL. So, mass of water will be calculated as follows.
density =
1 g/ml =
mass = 175 g
It is known that 18 g of water contains 1 mole of water. Hence, number of moles present in 175 g of water will be calculated as follows.
No. of moles =
=
= 9.72 mol
This means that we have 9.72 moles of ethanol also.
Hence, volume of ethanol present in 175 ml of water will be as follows.
No. of moles of ethanol =
9.72 mol =
Volume = 566.69 ml
Thus, we can conclude that 566.69 ml volume of ethanol contains the same number of molecules as are present in 175 ml of .
The basic building block for protein is amino acid.
