Answer:
the occur near the equator bc its- bc its warm and they get weak bc it slows them down
Explanation:
Answer: The mass of blue copper sulfate is 3.5 g
Explanation:
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The chemical equation for the heating of copper sulfate crystals is:
Let the mass of blue copper sulfate be 'x' grams
We are given:
Mass of copper sulfate powder = 2.1 grams
Mass of water = 1.4 grams
Total mass on reactant side = x
Total mass on product side = (2.1 + 1.4) g
So, by applying law of conservation of mass, we get:
Hence, the mass of blue copper sulfate is 3.5 grams
Just be nice, and compliment her
Answer:
the terminator because i did this test
97.2g H20 x 1mole/18g of H2O x 6.022x10^23 molecules/1mole= 3.25 x10^24 molecules of H2O
hope this helps! :)
