<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>
Answer:
A-Metals
Explanation:
because they have valence electrons
Answer:
21000000 m/s
Explanation:
Data obtained from the question:
Speed of light = 300000000 m/s
Speed of Alpha Particle =.. ?
From the question given above, the speed of the alpha particle is 7% of speed of light. Since we know the value for the speed of light, therefore, we can obtain the value for the speed of the alpha particle as follow:
Speed of Alpha Particle = 7% x speed of light
Speed of Alpha Particle = 7/100 x 300000000
Speed of Alpha Particle = 21000000 m/s
Lol that’s sad lollllllllllllllllllllp
