The answer is a. the atomic number represents the total protons and since the atom is neutral the number of protons and electrons are the same. therefore your answer is a.
Valence Electron because the more valence electrons an atom can contribute the shared pool, the stronger the metallic bonds will be
Answer:
Bottle B has a higher temperature than Bottle A.
Explanation:
We have to consider something very important here and that is the ability of the molecules of CO2 and those of air to trap heat.
CO2 molecules are better able to trap heat since it is among the green house gases.
Since CO2 is a greenhouse gas, the temperature of bottle B is higher than that of bottle A because more heat is trapped by the gas in bottle B than the gas in bottle A.
The number of unique open-chain structures corresponding to the molecular formula C₃H₅Cl is two.
<em>Step 1</em>. Draw <em>all possible connections of three carbon atoms</em>.
The is only one possibility (See first image below).
<em>Step 2</em>. Put the <em>Cl in all possible unique positions</em>.
There are only <em>two</em> possibilities: on an end carbon or on the middle carbon (see second image below).
Thus, there are only two isomers of C₃H₅Cl.
