Answer:
5.66g/ml
Explanation:
Mass of Metal Slug, m = 25.17g
Volume of container (flask), v = 59.7ml
Mass of Methanol, M = 43.7g with density, d = 0.791g/ml
Therefore,
Volume of Methanol = M/d = 43.7 / 0.791 = 55.25ml
Volume of Metal slug in the flask = v - V = 59.7 - 55.25 = 4.45ml
Density of Metal slug = mass of metal slug / volume of metal slug
= 25.17 / 4.45 = 5.66g/ml
The Sea and the ocean are just different terms that mean same thing
Answer:
Addition of a catalyst can speed up a reaction by providing an alternate reaction pathway that has a lower activation energy
Explanation:
A catalyst is an agent that increases the rate of a chemical reaction by providing an alternate pathway for the reaction that requires a lower activation energy. As the requirement for activation energy is less in the presence of a catalyst, there are more reactant particles becoming involved in the chemical reaction and as such there are more products formed per unit time, or there is an increase in the rate of the reaction
Example of catalyst include
1. Addition of potassium permanganate to hydrogen peroxide to aid in the rapid decomposition into water and oxygen
2. Platinum serves as a catalyst in the complete combustion of carbon monoxide into carbon dioxide.
Answer:
The word "Halloween" comes from All Hallows' Eve and means "hallowed evening."
Halloween's origins can be traced back to the ancient Celtic festival known as Samhain, which was held on November 1 in contemporary calendars. It was believed that on that day, the souls of the dead returned to their homes, so people dressed in costumes and lit bonfires to ward off spirits.
Explanation:
Depends on the situation. If the nucleophile is already in excess, then no the reaction will not occur faster
