... where is the image??
Here is an example though:
If you were given NaCl (this is he chemical formulafor table salt) you could identify Na (first column, or group, on your periodic table (PT) and 2nd row, or period, on your PT) as sodium.
The Cl you could identify as Chloride.
The statement that the friend made is not true. most of the mass of the plant is from carbon. the carbon comes from carbon dioxide which is used during photosynthesis. the left over carbon from photosynthesis is used to to help the plant gain mass. there is a process for this which is called cellular respiration
Answer:
Explanation:
Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground.
The compound that would be most reactive is Ethyne (answer A)
<u><em> explanation</em></u>
- Ethyne is the most unsaturated among the four compounds ( <em> it has a triple bond between the two carbon atoms) .</em>
- The triple bond in ethyne is made up of 1 sigma bond and 2π bond.
- <em>The 2π bond are weaker and can easily break which make Ethyne more reactive than Ethene, methane and Ethane.</em>
We see in the given name of the hydrocarbon that the root word is pentane from 2,2,4-trimethylpentane. Pentane is a hydrocarbon chain that contains 5 carbon atoms. Therefore, the answer to this item is 5 carbons.
