<em>Answer:</em>
- Organic compounds are those which are derivatives of hydrocarbons. They are classified into following functional groups.
<em>Alkane: </em>
- Alkane are simplest hydrocarbons.
- They have general formula CnH2n+2. These hydrocarbons contain single bond.
- For example ethane , H3C----CH3.
<em>Alkene:</em>
- Alkene are most reactive.
- They have general formula CnH2n.
- These contain double bond in their structure.
- For example , ethene, H2C=CH2
<em>Alkyne:</em>
- These are less less reactive as compare to alkenes.
- They have general formula CnH2n-2.
- They contain triple bonds in their structure.
- For example Acetylene HC≡CH
<em>Alcohol:</em>
Alcohol have functional group OH. They have general formual R---OH, R may be alkyl group.For example Ethanol H3CH2C---OH
<em>Amine:</em>
- Amine contain NH2 F.G.
- They have general formula R---NH2.
- There are three types of amine like primary, secondary and tertiary amine.
- For example H3CH2C---NH2
<em>Aldehyde:</em>
- Aldehydes have CHO F.G .
- They have general formula R--CHO.
- For example H3CH2C---CHO
<em>Ketone:</em>
- Ketones have R--CO--R functional group.
- For example acetone H3C---CO---CH3
<em>Carboxylic acid:</em>
- They functional group COOH.
- Their general formula is R---COOH.
- For example Acetic acid H3C---COOH
Answer:
what is the English translation, id like to help
Explanation:
Astatine is At in the periodic table, hope I helped :))
Answer:
Option D is correct
Explanation:
The individual mass of reactants in the reaction are
Calcium Oxide (CaO) = amu
Carbon dioxide (CO2) amu
Since this reaction is a simple addition reaction in which no mass of the reactants is wasted. Also, no energy is released accompanied by conversion of mass into energy.
Hence, total mass of reactants would be equal to the mass of the product.
Thus, mass of calcium carbonate i.e CaCO3 is
amu
Hence, option D is correct
Answer:
The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in
the products
Explanation:
For an equation to termed balance, the number of atoms of elements in the reactants must be equal to the number of atoms of the same element in the product.
The law of conservation of mass states that matter can neither be created nor destroyed during a chemical reaction but changes from one form to another. An unbalanced equation simply means that matter have been created or destroyed. This implies that balancing equation supports the laws of conservation of mass
