Answer:
I think it's A or D im not sure which one..
We use prefixes in ionic compounds Don't use numeric prefixes like mono, di, tri, etc. when naming ionic compounds - they are used only to denote covalent molecular compounds.
<span>Yes, mass is conserved. When sodium hydroxide (clear solution) and copper sulfate (blue solution) are mixed, they form a copper hydroxide (a blue solid) and sodium sulfate (a clear solution).
This can be tested simply. First weigh the masses (10 g and 57 g, which totals 67 g)) of the two starting solutions prior to mixing. Then mix and allow the reaction to occur and weigh the mass of the mixture (10g + 57 g = 67 g). The two solutions should have the same mass and therefore demonstrate conservation of mass.</span>
A I think because each side cancels out the other opposite side
