There would be a 2 infront of the NH3 and and 2 Infront of the H2O
Answer:
c. differ in electronegativity
Explanation:
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive
. The bond is polar.
When the elctronegativity difference is 0.4 or less than 0.4 the bond is non polar.
if the electronegativity difference is greater than 0.4 the bond is polar.
Answer: oxidizing agent:
reducing agent:
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.
On reactant side:
Oxidation state of magnesium = 0
Oxidation state of chlorine = 0
On product side:
Oxidation state of magnesium = +2
Oxidation state of chlorine = -1
The oxidation state of chlorine reduces from 0 to -1, it is getting reduced. The substance which gets reduced, oxidize others and called as oxidizing agent.
The oxidation state of magnesium increases from 0 to +2. Thus, it is getting oxidized. The substance which gets oxidized, reduces others and called as reducing agent.
<u>Answer:</u>
An example of a capital good is "the government will open another public school in the area".
<u>Explanation:</u>
A capital good or complicated products and systems or (CoPS) is a reliable commodity used in the manufacturing of goods and services. These are one of three kinds of consumer commodities, while the other two are property and labor.
The three are also commonly referred to as primary production factors.They are recorded on a company's balance sheet as assets, and can be depreciated over time. Capital goods instances include furniture, buildings, machinery, equipment and fixtures.
