ionic bonds- atoms must ionize to bond and are metal/nonmetal
covalent- atoms do not need to ionize but can be polar or nonpolar to stay together since it doesn’t ionize and are nonmetal/nonmetal
Answer:
E. The atoms in amorphous silica do not pack as efficiently in three dimensions as compared to the atoms in quartz.
Explanation:
Quartz is a crystalline structure with a lattice which is very compact and produces flat faces that align with one another causing high density.
Silica has covalent bonding and forms a network structure. Silica, SiO2 is an amorphous solid and does not posses the same lattice or crystalline structure as Quartz, making it less dense.
Answer: Yes
Explanation:
due to the nitrogen atom and its lone pair is in opposition to the moment associated with the three polar N-F bonds in NF3. NCl3 also has a small dipole moment
Answer:
a. 4KCN
Explanation:
Four is a coefficient found in the chemical formula 4KCN.
KCN is potassium cyanides.
A coefficient is a number that is written before a chemical compound. It is usually used to balanced reaction expression.
Chemically such numbers indicate the number of moles or volume of that specie.
Since KCN is the only compound with 4 before it, so, the solution is KCN
