Why the NaOH solution is heated before adding BaCl2 in the two solutions method for determination of purity of NaOH sample?
Why the NaOH is heated before adding in BaCl2 for determination of purity of NaOH sample?
What sample most likely has the lowest density?
Liquid mercury
What happens to the density of a gas sample collected in a balloon as the sample is heated?
The air becomes less dense as it expands making the balloon appear to self inflate.
What is a capillary melting point?
The sample is placed in a sealed capillary and heated up to the melting.

0.667
Calculating Mercury in Mercury oxide by gravimetric analysis?
First take the mercury oxide and heat it so that it decomposes completely. This will drive off the oxygen gas and leave you with elemental mercury. Record the exact mass of the mercury that you have left at the end of the reaction. Divide this mass of mercury by the original mass of your mercury oxide sample and multiply by 100. This will be the percent mercury by mass in your original sample.
How is a sample oxygen different from a sample of a water?
Oxygen is just O and water is H2O
What fraction of a sample remains after three half lives?
An eighth remains.
