Which event is an example of an endothermic reaction?.

1 answer:

7 0

For a reaction to be endothermic we have a process where heat is absorbed from a product and the end result is the product being colder than it originally was.

An event that can be a good practical example is using an ice pack on your arm. Your arm is warm before an ice pack is applied. After you apply an ice pack and leave it there for a while and then take it off, the site where the ice pack was would be colder than it was before the ice pack. Hope this helps!

Which of these substances has the highest pOH? 0.10 M HCl, pH = 1 0.001 M HNO3, pH = 3 0.01 M NaOH, pH = 12 The answer is 0.10 M

Naya [18.7K]

Answer:On these combined scales of pH and pH it can be shown that because for water when pH = pH = 7 that pH + pH = 14. This relationship is useful in the inter conversion of values. For example, the pH at a 0.01 M solution of sodium hydroxide is 2, the pH of the same solution must be 14-2 = 12.
