Answer:
An increase in temperature lead to more effective collisions between reactant particles
increase in the rate of a chemical reaction because the number of molecules with sufficient energy to react increases.
Explanation:
Explanation:
A catalyst has no effect on the equilibrium state, but it enables equilibrium to be reached more quickly by decreasing the “energy of activation”. In fact, a catalyst affects forward and reverse rates equally.
Answer:
A front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity.
Answer:
The hydronium ion in neutral solution has the concentration of 1.0 x 10⁻⁷.For acidic solution, the concentration of hydronium ions is greater than 1 × 10⁻⁷ that the pH be lower than 7.
Explanation:
Answer: The distillation flask being heated in a heating mantle. The vapors condense and drip from the condenser into the flask. As the distillate begins to drop from the condenser, the temperature observed on the thermometer should be changing steadily.
Explanation:
answer above
