Achemist pours 1 mol of zinc granules into one beaker and 1 mol of zinc chloride powder into another beaker. what do the two samples have in common?

Beaker-1 has same number of zinc atoms as that of the zinc ions in beaker-2.

Explanation:

In beaker-1 , we have added 1 mol of zinc granules.

1 mol = atoms

In beaker-1 atoms of zinc are present.

In beaker-2, we have added 1 mole of zinc chloride.

1 mole of zinc chloride gives 1 mole of zinc chloride gives one mole of zinc ions and 2 moles of  chloride ions.

1 mol of Zinc ion = ions

The both samples have:

zinc atoms = zinc ions

Beaker-1 has same number of zinc atoms as that of the zinc ions in beaker-2.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
