Answer:
The molecular formula of Carbon Dioxide is CO2
Answer:
0.435 M
Explanation:
In case of dilution , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = initial concentration ,
V₁ = initial volume ,
M₂ = final concentration , i.e. , concentration after dilution ,
V₂ = final volume .
from , the question ,
M₁ = 0.725 M
V₁ = 300 mL
M₂ = ?
V₂ = 300 mL + 200 mL = 500 mL
Since, the final volume of solution would be the summation of the initial and final volume.
Using the above formula , the molarity of the final solution after dilution , can be calculated as ,
M₁V₁ = M₂V₂
0.725 M * 300 mL = M₂ * 500mL
M₂ = 0.435 M
Explanation:
Thermal energy from the sun's heat, and mechanical energy from previous tides and waves. Oceans are one of the largest solar collectors.
B. Radiant belongs to the electromagnetic force and travels through the electromagnetic field.
Answer:
The necessary equations necessary are explained in each step in the solution.
Explanation:
For conversion of methanol gas at 65°C to -112°C
the equations would be as follows,
step 1 : gas at 65°C to liquid at 65°C
q = n(-37 kJ/mol)
step 2 : liquid at 65°C to liquid at -94°C
q = n(81.1 J/mol°C), where dT is negative
step 3 : liquid at -94°C to solid at -94°C
q = n(-3.18 kJ/mol)
step 4 : solid at -94°C to solid at -112°C
q = n(48.7 J/mol°C), where dT is negative
