Answer:

B. Preliminary conclusion

Explanation:

The answer is B because a hypothesis is really an educated guess you make in regards to a question, usually before performing an experiment, so it can't be a preliminary conclusion because you don't really have any solid evidence to support your hypothesis, you only have background information. You will either be able/not be able to support your hypothesis after your expirement has concluded.

Give one chemical property of soda ash.

Elenna [48]

<span>Soda ash is sodium carbonate, Na2CO3. One chemical property of this compound is its basicity, which is measured by the pKb. The pKb for sodium carbonate is 3.67. It is the result of the dissociation of Na2CO3 in water: Na2CO3 + H2O = Na HCO3 + Na (+) + OH(-). This pKb means that it is a highly basic compound. pKb = log { 1 / [OH-] }, so pKb is a measure of the concentrations of OH- ions, which is the basiciity of the compound. </span>
