42cubic centimeter are in the block
volume is 48
To solve this we use the
equation,
<span> M1V1 = M2V2</span>
<span> where M1 is the
concentration of the stock solution, V1 is the volume of the stock solution, M2
is the concentration of the new solution and V2 is its volume.</span>
<span>2.0 M x V1 = 0.50 M x 200 mL</span>
<span>V1 = 50 mL needed</span>

Are you sure it isn’t SO3+H2O = H2SO4 because that would be combination (synthesis) A+ B=AB
Or SO3 + H2SO4 = H2S2O7
Because that would also be synthesis
Answer:
The atoms of some elements share electrons because this gives them a full valence shell just like the nobal gases GOOD LESSONS ♡
