As you can see, the unit of heat of vaporization is in kJ/mol, while the unit for entropy of vaporization is in J/mol·K. Since it is vaporization, this occurs at the boiling point. Thus, the formula would be:
Boiling Point = ΔHvap/ΔSvap
Make sure the units are consistent.
Boiling point = 55.5 kJ/mol * 1000 J/kJ / 148 J/mol·K = <em>375 K or 102°C</em>
The answer is so it didn't burn.
Answer:
on the right side, because it is a product
Explanation:
photosynthesis is the chemical reaction with the help of which plants produce chemical energy with the help of light energy.
_______________________________________________
The general standard for writing chemical reaction is that
- The chemical which are input to the process of chemical reaction are written on left hand side . They are known as reactant.
- The output of chemical reaction are written on right side. They are termed as product.
- Transition of reactant to product is shown by arrow.
Chemical reaction for photosynthesis is given by below equation
6CO2 + 12H2O + light ----------------> C6H12O6 + 6O2 + 6H2O
We can see that 6 molecules of light combines with 12 molecules of water to give one molecule of glucose and 6 molecules of both water and oxygen.
As, oxygen is the output of photosynthesis process, it is written on the right-hand side of equation and is product of this reaction.
.
Thus, of the options given below for
In an equation for photosynthesis does oxygen belong
on the right side, because it is a product
Answer:
An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion.
Answer:
P = 162 KPa
Explanation:
Given data:
Number of moles = 2 mol
Volume of gas = 30.0 L
Temperature of gas = 293 K
Pressure of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
P = nRT/V
P = 2 mol ×0.0821 atm.L/ mol.K ×293 K/ 30.0 L
P = 48.11 atm.L/ 30.0 L
P = 1.6 atm
atm to kelvin:
1.6×101 = 162 KPa
