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,
= 
= 
= 
Answer:
130
Explanation:
This is because that 3atm of N2O4 is used up for the 6atm of NO2, so 1 atm N2O4 is left. Resulting in In(1/4).
Table salt = ionically bonded molecule, sodium transfers one valence electron to chloride, NaCl
Table sugar = covalently bonded molecule
Sorry, that’s all I know.

Answer:
The temperature increases from 23.0 C to 37.0 °C
Explanation:
<u>Step 1:</u> Data given
DH = -44.4 kJ/mol
mass NaOH = 13.9 grams
mass of water = 250.0 grams
Initial temperature = 23°C = 295 K
Final temperature = TO BE DETERMINED
Specific heat = 4.18 J/g*K
<u>Step 2: </u>Calculate change in temperature
13.9 grams/ 40 g/mol * 44.4 kJ/mol = 15429 J
15429 J = (massNaOH + mass water) * 4.18 * ΔT
15429 = 263.9 *4.18 * ΔT
ΔT = 14°C
<u>Step 3:</u> Calculate final temperature
ΔT= 14°C = T2 - 23°C
T2 = 23 +14 = 37 °C
The temperature increases from 23.0 C to 37.0 °C
