No because the second atom has 1 more neutron and 2 more electrons.
Answer:
This is a typical stoichiometry question.To answer this question you want to get a relationship between
N
a
2
O and NaOH.
So you can get a relationship between the moles of
N
a
2
O
and moles of NaOH by the concept of stoichiometry.
N
a
2
O +
H
2
O ----------------> 2 NaOH.
According to above balanced equation we can have the stoichiometry relationship between
N
a
2
O and NaOH. as 1:2
It means 1 moles of
N
a
2
O is required to react with one mol of
H
2
O to produce 2 moles of NaOH.
in terms of mass 1 mole of
N
a
2
O has mass 62 g on reaction with water produces 2 moles of NaOH or 80 g of NaOH.
62 g of
N
a
2
O produces 80 g of NaOH.
1g of NaOH is produced from 62/80 g of
N
a
2
O
1.6 x
10
2
g of NaOH will require 62 x 1.6 x
10
2
g / 80 of
N
a
2
O
124g of
N
a
2
O.
Explanation:
Answer:
POCl3
Explanation:
A compound is a substance made up of atoms of different elements. The number of atoms each element posseses make up the chemical formula of the compound. In this question, a certain compound is made up of three chlorine atoms (Cl3), one phosphorus atom (P), and one oxygen atom (O).
Combining these atoms of different quantity together, this means that the compound will have a chemical formula: POCl3. This compound is called phosphorus oxychloride.
The answer to this question should be 3. <span>adding research resources during an investigation

The answer 1 and 2 are similar. Discovering a new variable mean that you wouldn't control it at the beginning of the research. It would be too late if you try to control it. Incorrect measurement definitely will cause an error.
