Answer:
Production of Citric Acid
It is an organic carboxylic acid and can be extracted from the juice of citrus fruits by adding calcium oxide to form calcium citrate, which is an insoluble precipitate that can be collected by filtration; the citric acid can be recovered from its calcium salt by adding sulfuric acid.
Explanation:
Answer:
( B) They all have their valence electrons in the same type of subshell.
Explanation:
With each period, a new shell is added to the atom.
Further, the groups are classified based on the type of subshell the last electron enters and number of valence electrons.
For all elements of same group, the last electron enters the same type of subshell.
Say, for group 1, last electron enters s orbital and they have 1 valence elctron.
for group 17, last electron enters p orbital and they have 7 valence electrons.
(A) and (D) are wrong because, energy level of the valence electrons is determined by the principle quantum number n and l and not by the type of subshell(only l) they enter.
(C) if the valence electron enters p orbital, then the elements will be placed in the p- block.

to get more points and to i have no clue what that answer is
Answer:
The number of atoms contained by one molecule of Iron (II) Sulfate are 6.
Explanation:
Iron (II) Sulfate is mage up of two parts. One is the Positive part which constitutes of Fe⁺² and a negative part which constitutes of a polyatomic anion i.e. SO₄²⁻. As there are four Oxygen and one sulfur atom in sulfate Ion so sulfate ion contains 5 atoms in total. Therefore, five atoms from sulfate iona dn one atom of Iron ion makes a total of 6 atoms in one molecule of Iron (II) Sulfate.
Answer:
The correct answer is 372852.9 g.
Explanation:
First, we must look for the relationship between the masses in grams and pounds.
To get an approximate result, the relationship between pounds and grams found is:
1 lbs = 453.592 g
Now we must use this relationship as a conversion factor in the following way:
8.22 lbs * 
= 372852.9 g
The mass expressed in grams for 8.22 lbs is 372852.9 g.
Have a nice day!
