Answer:
The combination of oxygen with other substances to produce new chemical products is called <u>Oxidation</u>.
Explanation:
Oxidation reactions are defined as,
In terms of Inorganic chemistry:
(i) <u>Removal of Electrons: </u>
Example: Mg → Mg²⁺ + 2 e⁻
(ii) <u>Addition of Oxygen:</u>
Example: 2 Mg + O₂ → 2 MgO
In terms of Organic chemistry:
(i) <u>Addition of Electrons: </u>
Example: Cl₂ + 2 e⁻ → 2 Cl⁻
(ii) <u>Addition of Hydrogen:</u>
Example: H₂CCH₂ + H₂ → H₃CCH₃
Answer:
The answer to the question is 0.0122 m/s
Explanation:
The rate of a reaction is the measure of the change in concentration of a reagent within a specific time frame. Reaction rate of a substance can be calculated by finding the division of the concentration change of the substance and the time required to undergo the change in concentration.
The initial number of moles of X = 0.732 moles and final number of moles of X = 0 moles and the time it took to effect the change = 60s
then the rate of reaction = 
= 0. 0122 moles per second
the rate of the reaction involving X = 0.0122 m/s
Answer:
Rainforest
Explanation:
Swamps are permanently filled with water
and Tundras are dry and cold so the answer should be Rainforest
Answer:
1. B
2. C
Explanation: The law that the properties of the elements are periodic functions of their atomic numbers. And the second one is, most of the air we breathe is made of oxygen.
I'm pretty sure the formula is 2n(/\) 2
