I would go with <span> a molecular compound</span>
If polar covalent bonding results in a molecule with a positively-charged end and a negatively-charged end, the molecule is called D. a dipole.
Answer:
239 L
Explanation:
1. Propane reacts with oxygen to produce carbon dioxide and water:

Firstly, 3 carbon atoms are required on the right:

Secondly, 8 hydrogens in total (4 water molecules) are required on the right:

On the right, we have a total of 10 oxygen atoms, this implies we need 5 oxygen molecules on the left:

2. Calculate moles of propane using the the ratio of mass to molar mass:

According to the stoichiometry, we have 3 times greater amount of carbon dioxide:

Use the ideal gas law to solve for volume:

Sr(NO3)2 ---> Sr²⁺ + 2 NO3⁻
from the reaction 1 mol 1 mol 2 mol
from the problem 0.5 mol 0.5 mol 1 mol
Answer:
Two unlike charged ions.
Explanation:
The positive charge on one and the negative on the other helps form the ionic bond.
Ionic bonding is the complete transfer of valence electron(s) between atoms. In these types of bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion..
Ionic bonding is observed because metals have few electrons in their outer-most orbitals. By losing those electrons, these metals can achieve noble gas configuration and satisfy the octet rule.
