Answer:
Carbons 1 and 3
Explanation:
We must remember that by definition <u>alpha carbon</u>s are the carbon (or carbons) next to the carbon that contains the main group. In this case, the main group is the carbonyl group (C = O) in the middle of the molecule. In the acetone molecule, we have three carbons, the carbons neighboring the carbon of the carbonyl group (carbon two) will be the <u>alpha carbons</u>. (Red and blue carbons or carbons one and three)
See figure 1 for further explanations.

321.1 g of strontium phosphite will contain 0.76 moles of strontium phosphite in the beaker.
<u>Explanation:</u>
It is known that 1 mole of any substance is equal to the molar mass of that substance. So for the case of strontium phosphite, the molar mass is found to be 420.8 g/mol.
This means 1 mole of Strontium phosphite will contain 420.8 g of strontium phosphite.
Then 1 g of strontium phosphite will have 
moles of strontium phosphite.
So, 321.1 g of strontium phosphite will contain 
Thus, 321.1 g of strontium phosphite will contain 0.76 moles of strontium phosphite in the beaker.
Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.
One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces.
Answer:
C
Explanation:
The ions are first accelerated electrically, and then bended magnetically to sort them and record them.
The answer is going to be the first option. What they found out is that atoms are made up of mostly space, but there is a positively charged mass in the center of the atom.
