Answer:
5.57 x 10^24 atoms of Mg
Explanation:
1 mole = 6.023x10^23 items, by definition. Atoms, in this case.
0.25 moles would be (0.25mole Mg )(6.023x10^23 atoms Mg/mole Mg) = <u>5.57 x 10^24 atoms of Mg</u>
Answer:
The evaluation is correct.
Explanation:
Water has hydrogen bonding which is stronger than the dipole-dipole IMF of acetone. Thus, acetone has weaker IMFs.
Answer: Atomic Mass
Explanation:
The Atomic mass of an atom is the number of protons and neutrons in the atom and is measured in atomic mass units (amu) but can still be measured in kilograms.
For example, if the number of neutrons in an atom is 8 and the number of protons is 6, the atomic mass of the atom is 14.
Answer:
Erosion.
Explanation:
It can be as small as a grain of sand or as large as a boulder. Sediment moves from one place to another through the process of erosion. Erosion is the removal and transportation of rock or soil. Erosion can move sediment through water, ice, or wind.
