Answer:
Decreasing surface area of the solid in the liquid.
Explanation:
I don't know how to explain this without using. an example. So, here it is: If you were dipping bread in water, the bread would be completely soaked if you dipped the whole thing, but if you only allowed one part of the bread to be in the water, it would take longer for the water to soak all the way into it. The amount of surface area that is allowed to touch what is making the solid dissolve determines how quickly the whole thing will be dissolved.
Answer:
7,9,11
Explanation:
this is because water includes 0H, which would mean that it is more than 6
Answer:
no it is a ionic compound
It will likely give up its valence electron to the other compound, forming stable octets on each of the newly formed ions. These ions have opposing charges, and tend to form strong ionic lattices. A good example of this is NaCl, which contains Na+ ions that have given up their one valence electron and Cl- ions which have accepted that electron.
Hope this helps!
We need to dilute 0.400 mol of copper (II) sulfate, how do we know, how many weigh of

we have to dilute??
It's simple.

Using a periodic table we can find the molar mass of


Then

now we can replace it


Then we have to dilute 63.84 grams of copper (II) sulfate in 1 L of water to obtain a solution with 0.400M
