<p>If there was a problem that said "Will the reaction of ____ and ____ go to completion", how would one go about solving that?</p>
<p>Ex) The burning of carbon with excess O2 to form CO2 will go to completion" True or false?</p>
<p>The subject is “the burning of carbon”, so the question is asking whether the carbon will be completely burned. If there is excess oxygen, then yes, the carbon will be completely burned. Answer is true. </p>
<p>I also had another question.</p>
<p>When HCL gas and NH3 gas come into contact, white smoke forms. True or false?</p>
<p>Is this just a factoid question where you just have to know it beforehand, or is there another way of solving it?</p>
