the burning of wood is a chemical reaction between cellulose molecules in the wood and oxygen the products are carbon dioxide an
d water what would you have to do in order to prove that this reaction obeys the law of conservation of mass?
1 answer:
Put the <em>wood and excess oxygen in a closed contai</em>ner that contains some device that can create a spark (to start the reaction).
Determine the <em>mass of container + contents</em>.
<em>Start the reaction</em> and, after everything has cooled down, again determine the <em>mass of container + contents</em>.
If the two masses are the same, you have demonstrated that the reaction obeys the Law of Conservation of Mass.

KOH = 90g
KOH = 57 g/mol
K = 40g/mol
57g/mol contains 90 g
40g/mol will contain?
= 63.15 g
The mass of K is 63.15g
