Answer:
The answer is "3.57 and 0.07".
Explanation:
Using the slop formula:
Given:
length path
from calibration it is found that
Kc' =Kc^1/3
=3√0.0061
=0.182716013
The number of neutrons in an atom is the number of particles present in its nucleus.
The atomic number is the number of protons whereas the mass number is the number of protons and number of neutrons together
This implies that the number of neutrons is the atom's mass number
Mg + 1/2 O2 → MgO
1 mol = 24 g of Mg
X mol = 12 g of Mg
x = 0.5 moles of Mg
Mg :MgO = 1:1 (coefficient from equations using mole ratio)
So
0.5 moles of MgO
1 mol MgO = (24+16) g = 40 g
0.5 moles of MgO = 0.5 × 40
= 20 g of MgO produced
When waters salinity increases it’s freezing point will decrease. This is one of the reasons why people salt the roads after a snow storm.
