The difference is that in a nuclear reactor it uses normal pressures and temperatures that are relative to earth using fission , where as in the sun, fusion happens and with that comes extremely high temperatures and bone squishing pressures.
Answer:
6 M
Explanation:
n = m/M
m= 60g
M(NaOH)= 23 + 16 + 1 = 40
n= 60/40 = 1,5 mol
Therefore c = n/ V = 1,5/ 0,250 = 6
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:
It proposed that the positive charge was concentrated in the nucleus.
i just took the test. this is right.
