Answer:

Measuring the level of lead in drinking water is the job of an analytical chemist.

Explanation:

The work of analytical chemists is to analyse the chemical properties and nature of the substance.

They have to perform different experiments using instruments and then conclude about the nature of the sample, chemical properties of the sample, toxicology, concentration and other properties of the samples and then the analytical chemists should give a detailed report on the measurements or analysis he or she has carried out.

So the measuring of lead in drinking water forms under the measurement of toxicology of water as lead is toxic on reaction with water so it is the job of analytical chemists only.

Answer : 1.12 grams

Yo find the mass of the sample, you take the increased mass and subtract the original mass.

6.130 - 5.010 = 1.12

iris [78.8K]

Answer:

I think that the trend that would be seen in the time column of the data table would be that the number of seconds would increase. I know this because for each flask, the concentration of sodium thiosulfate decreases, since less of it is being mixed with more water. Also, when the concentration of a substance decreases, then the reaction rate also decreases, as there will be fewer collisions with sulfuric acid if there are fewer moles of sodium thiosulfate. When there are fewer collisions in a reaction, the reaction itself will take longer, and so when the sodium thiosulfate is diluted, the reaction takes more time.

Explanation:

I verify this is correct.
