Practice Chemistry Problems

The best way to learn how to do chemistry problems is to practice, practice, practice. Chemistry texts work an example or two and often have answers to questions in the back of the book, but it's helpful to see other fully worked examples. Here are some common types of problems encountered by students their first week of chemistry. Try to work out the problem before checking the answer: if(zs>0){if(zSbL250)gEI("spacer").style.height=Math.floor(e[0].height/12)+17.5+'em';else{var zIClns=[];function walkup(e){if(e.className!='entry'){if(e.nodeName=='A'||e.style.styleFloat=='right'||e.style.cssFloat=='right'||e.align=='right'||e.align=='left'||e.className=='alignright'||e.className=='alignleft')zIClns.push(e);walkup(e.parentNode)}}walkup(e[0]);if(zIClns.length){node=zIClns[zIClns.length-1];var clone=node.cloneNode(true);node.parentNode.removeChild(node);getElementsByClassName("entry",gEI("articlebody"))[0].insertBefore(clone,gEI("spacer"))}}}};zSB(2);zSbL=0
