Answer:
Take approx 41.7 mL of 12-M HCl in a 1.00-L flask and fill the rest of the volume with distilled water.
Explanation:
Hello,
In this case, for the dilution process from concentrated 12-M hydrochloric acid to 1.00 L of the diluted 0.50M hydrochloric acid, the volume of concentrated HCl you must take is computed by considering that the moles remain constant for all dilution processes as shown below:

Which can also be written in terms of concentrations and volumes:

Thus, solving for the initial volume or aliquot that must be taken from the 12-M HCl, we obtain:

It means that you must take approx 41.7 mL of 12-M HCl in a 1.00-L flask and fill the rest of the volume with distilled water for such preparation.
Best regards.
Answer:
B.
He could breed his peach plants with peach plants that can survive the frost.
Explanation:
Tom can best solve his problem by breeding his peach plants with the ones that can survive the frost.
- This is known cross breeding
- The goal of cross breeding is to produce offspring that contains the traits of both of the parents or an improved hybrid.
- If Tom can cross breed the failing peaches with the successful winter resistant ones, he can ensure better production.
- The new hybrid will therefore will be genetically superior and adapted to the prevailing environmental changes.
