The balanced reaction:
<span>4Na + O2 = 2Na2O
We use the relation of the substances and the amount of sodium to determine the theoretical yield of the reaction. This yield is the amount produced if all the reactant is consumed.
2.55 mol Na (2 mol Na2O / 4 mol Na) ( 61.98 g / 1 mol ) = 79.02 g Na2O
Percent yield = 75.0 / 79.02 x 100 = 94.91%</span>
E. solid, hard yet brittle, very high melting and boiling point
Answer:
4
Explanation:
there are four moles of aluminium
Ok, I see you have written the radioactive decay correctly, but what exactly is your question?
Answer:
Bond points will go astray from their perfect values agreeing to the run the show that solitary sets repulse other electrons more unequivocally than holding sets. In spite of the fact that solitary sets are clearly littler than molecules, they got to be closer to the core of an molecule than a holding combine.
