Answer:
The ration of molar concentration is "2.5".
Explanation:
The given values are:
Average density of salt water,
= 
Net pressure,
= 
Increase in pressure,
= 
Now,
The under water pressure will be:
= 
= 
= 
= 
hence,
The ratio will be:
= 
or,
= 
= 
= 
I think that it is true to the bone
It can cause a deadly reaction to skin if not treated for a long time
Answer:
If the reaction is going from left to right it would be synthesis, if going right to left it would be decomposition.
Explanation:
Na2O (s) + 2CO2 (g) + H2O (g) = 2 NaHCO3 (s)
Left Side
Na = 2
O = 6
C = 2
H = 2
Right Side
Na = 2
O = 6
C = 2
H = 2
Ok so is balanced already, though initial equation in question had an error in regards to the left hand side the ) should have been an O.
Hmm
Na2O (s) + 2CO2 (g) + H2O (g) = 2 NaHCO3 (s)
If it was going from right to left would be decomposition
But going from left to right it would be synthesis
