Explanation:
Start by comparing the moles of carbons on the left to number on the right. The number of moles on both side of the arrow should be the same.
Answer:
27) Double replacement
28) 2NaOH + H2SO4 --> Na2SO4 + 2H2O
Answer:
175 kJ
Explanation:
Activation energy can be defined as the potential energy that is needed to change reactants to products. This is the minimum energy required for the chemical reaction to take place. Thus, using the given figure:
Activation energy = activation complex - reactant energy
In the given figure, activation complex = 400 kJ
reactant energy = 225 kJ
Therefore:
Activation energy = 400 - 225 = 175 kJ
Answer: B. Unsaturated
Explanation: in a saturated/super saturated solution, more solute will not be able to dissolve.
