Answer:
See the answer below, please.
Explanation:
The bonds formed between metals and nonmetals are called ionics. These occur between atoms with electronegativity difference. Example: NaCl (Sodium Chloride)
Instead, covalent bonds are formed between two nonmetals (one or more electron pairs are shared). Example: H202 (hydrogen peroxide).
In the case of metal formed bonds, they are called metallic.
Answer
Ionic compounds are formed when metals react with non-metals . Ionic compounds held together by ionic bonds are classed as ionic compounds.
Explanation:
I used this to awnser this queston when I was a freshmen in high school.
Explanation:
Given elements:
F, Sr, P, Ca, O, Br, Rb, Sb, Li, S
Elements with the same chemical reactivity will belong to the same group on the periodic table. This implies that elements in the same column will have the same reactivity;
Li and Rb are both alkali metals in group 1
Ca and Sr are both alkali earth metals in group 2
F and Br are halogens in group 7
O and S are group 6 elements
P and Sb are both in group 5 on the periodic table
So these groupings show elements with the same chemical properties.
Based on ecological studies, the definitions below applies to the given terms:
- Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
- Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
- Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
- Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available
<h3>What is ecology and what are some terms in ecology?</h3>
Ecology is the study of living things and their interactions with their environment.
Some terms in ecology include:
- Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
- Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
- Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
- Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

The compound (A) is 2-bromo-pentane. See attached picture for the chemical diagram.
Explanation:
2-bromo-pentane (A) reacts with bromine (Br₂) under UV light to form 2,2-dibromopentane and HBr. Also 2-bromo-pentane (A) reacts with NaSH to from pentane-2-thiol, which have an asimetric carbon, and NaBr.
