<h3><u>Answer;</u></h3>
D. All the above
- Covalent compounds are always poor conductors of electricity while ionic compounds conduct electricity well when melted or dissolved.
- Covalent compounds can be solid, liquid or gas, but ionic compounds are solids.
- In covalent compounds the elements present are usually close together on the periodic table whereas in ionic compounds they are usually well separated.
<h3><u>Explanation;</u></h3>
- <u>Ionic compounds are compounds that are formed from strong electrostatic interactions between ions.</u> Ionic bonding occurs between a nonmetal, which acts as an electron acceptor, and a metal, which acts as an electron donor. The atoms involved in ionic bonding lose or gain electrons and form positively or negatively charged ions.
- <em><u>Ionic compound are good conductors of electricity both in molten and aqueous form,. while covalent compound are poor conductors of electricity.</u></em>
- <u>Covalent compounds on the other hand are compounds that have bonds where electrons are shared between atoms.</u> These types bonds mostly occur between nonmetals or between two atoms of the same element.
Answer:
Hydroxyl
Explanation:
A hydroxyl group is a functional group that attaches to some molecules containing an oxygen and hydrogen atom, bonded together. Also spelled hydroxy, this functional group provides important functions to both alcohols and carboxylic acids.
Answer: Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock.
Explanation: This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Answer:
1.02mol
Explanation:
Using the general gas equation below;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question,
P = 2.0 atm
V = 11.4L
T = 273K
n = ?
Using PV = nRT
n = PV/RT
n = 2 × 11.4/ 0.0821 × 273
n = 22.8/22.41
n = 1.017
n = 1.02mol
