First you need to write out the original equation.
It needs to be balanced, though, so after balancing it should look like this:
The ionic equation would look like this. (Only aqueous solutions can be split up).
The net ionic equation only contains the products that are not aqueous. Therefore, the final net ionic equation should be:
So your answer is C.
Answer:
1) 1,8066*10^24 molecules of water
2)2,4088*10^24 atoms of carbon
3)4,8176*10^24 atoms of oxygen
4)2,6071*10^23 molecules og NaCl
5)107,221 g of calcium bromide
6)0,0814 moles iron III nitrate
Explanation:
<span>A pure substance contains only one kind of molecule, and a mixture is a combination of two or more pure substances.</span>
Basically, an element<span> is made of only one kind of atom, while a </span>compound<span> contains the atoms of two or more </span>elements<span>.
Just to give you a good exaple:
Gold is made of only one kind of atom, so it's considered an </span>element<span>, but water is a mix of hydrogen and oxygen, so it's a </span>compound<span>.</span>
