There is no diagram attached but there are some ways by which you can find it too easily by yourself
Usually energy diagram uses ∆H .
So
- If ∆H is +ve means reaction is exothermic and energy is released
- If ∆H is -ve means reaction is endothermic and energy is absorbed
So observe∆H whether it. is decreasing or increasing ,
- If increasing then energy is being released and vice versa
To determine this, you can look at the molecular weight of that particular atom which is found on the periodic table. Carbon has a molar mass of 12.01 grams / mole. Sulfur has a molar mass of 32.06 grams / mole. This means one mole of carbon weighs 12.01 grams and one mole of sulfur weighs 32.06 grams. Therefore, one mole of carbon atoms has a smaller mss than one mole of sulfur atoms.
Answer:
Vanderwaals forces
Explanation:
CBr4 is a nonpolar molecule, nonpolar molecules usually possess vanderwaals forces between their molecules as their main attractive force.
CBr4 is nonpolar because the tetrahedral arrangement of the C-Br bonds cancel out the individual dipole moments of each C-Br bond thereby making the compound nonpolar, hence the answer above.
