There are 4 lone pairs of electrons present in the carbon dioxide molecule
Answer:
The presion is 0.6 atm
Explanation:
P1V1=P2V2
P2 = P1V1/V2
P2 = (4.00 atm * 0.30 L) / 2.0 L
P2= 0.6 atm
Conduct creates, convect rubs, and radiation gives heat.
Answer:
The given reaction is combustion reaction heat is also produced.
Explanation:
Chemical equation:
CH₄ + 2O₂ → CO₂ + 2H₂O
The given reaction is combustion of methane. When methane burn it produced water and carbon dioxide. Heat is also produced.
The given reaction followed the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
CH₄ + 2O₂ → CO₂ + 2H₂O
There are equal number of carbon hydrogen and oxygen atoms present on both side of equation. So it follow the law of conservation of mass.
<h3><u>Answer;</u></h3>
The statement above is <u>False</u>;
<h3><u>Explanation;</u></h3>
- Saturated hydrocarbons also known as alkanes contain only a single covalent bonds between carbon atoms. The common feature found in all saturated hydrocarbons is carbon-carbon multiple bonds.
- Unsaturated hydrocarbons are hydrocarbons in which all the valencies of carbon atoms are not fully utilized by single covalent bonds. They contain at least one double or triple bond in their structure.
- <em><u>Characteristic reactions of alkanes or saturated hydrocarbons are substitution reactions. Unsaturated hydrocarbons characteristics reactions are addition reactions.</u></em>
