The answer is B. The less mass then the less the gravity pulls on it
Answer:
B-It provides an explanation for many observations and accepted hypotheses.
The answer is NH4Cl!
Ionic bonding=cation + anion
- the cation ammonium (NH4) has a single electron in its valence shell, and Chlorine needs a single electron to fill its valence shell, and they stick together.
Covalent bond= involves the sharing of electron pairs between atoms
- present in Ammonium ion between Nitrogen and Hydrogen atoms
Answer:
solid at room temperature (with the exception of mercury)
usually shiny.
high melting point.
good conductor of heat.
good conductor of electricity.
low ionization energies.
low electro-negativities.
malleable – able to be pounded into sheets.
The orbits of the planets are coplanar because during the Solar System's formation, the planets formed out of a disk of dust which surrounded the Sun. Because that disk of dust was a disk, all in a plane, all of the planets formed in a plane as well.
