The element which can not loose electron easily and having electronagtive character is called non-metal it has following property-
1. it can not conduct heat and electricity
2. it is netiher ductile not malleable
3. it is not lsuturous and also not sonorous
In chemistry, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
decameters - meters: multiply by 10
meters to meters: multiply by 1
centimeters to meters: divide by 100
millimeters to meters: divide by 1000
For the rows at the bottom:
hectometer row: 100, multiply by 100, 4500
decameter row: 10, multiply by 10, 450
meter row: 1, multiply by 1, 45
decimeter row: 0.1, divide by 10, 4.5
centimeter row: 0.01, divide by 100, 0.45
im guessing theres a millimeter row at the bottom:
millimeter row: 0.001, divide by 1000, 0.045
hope this helps!
Answer: c. oxidation - gain of electrons
Explanation:
1. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Example:
2. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
Example:
3. Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
![M\rightarrow M^{n+}+ne^-](https://tex.z-dn.net/?f=M%5Crightarrow%20M%5E%7Bn%2B%7D%2Bne%5E-)
4. Dehydration reaction is defined as the reaction in which water is lost as product.
![CH_3CH_2OH\rightarrow CH_2=CH_2+H_2O](https://tex.z-dn.net/?f=CH_3CH_2OH%5Crightarrow%20CH_2%3DCH_2%2BH_2O)
5. Hydrolysis reaction is defined as the reaction in which water is used for decomposition.
Example: ![CH_3COOCH_2CH_3+H_2O\rightarrow CH_3COOH+CH_3CH_2OH](https://tex.z-dn.net/?f=CH_3COOCH_2CH_3%2BH_2O%5Crightarrow%20CH_3COOH%2BCH_3CH_2OH)
