Most of the compounds containing C and H are organic so A. CH4 is the correct option
<span>The relationship between the number of carbon atoms and boiling point is inversely proportional. In the alkane series of hydrocarbons, as the number of carbon atoms decreases, the normal boiling point of the compounds decreases. The reason behind this is that longer chains of molecules require more energy to separate the bonds while shorter chains or molecules with lower number of carbon atoms require less energy to break away from each other. Thus, low carbon molecules have lower boiling point.</span>
Answer:
compared to sodium, silicon has a higher ionization energy meaning it takes more energy to remove electrons.

Answer:
1.126 M
Explanation:
From the question given, we obtained the following:
Mass of LiBr = 98g
Volume = 1 L
Molarity of LiBr =?
Next, we'll determine the number of mole of LiBr. This is illustrated below:
Molar Mass of LiBr = 7 + 80 = 87g/mol
Mass of LiBr = 98g
Number of mole = Mass/Molar Mass
Number of mole of LiBr = 98/87
Number of mole of LiBr = 1.126 mole
Now, we can calculate the molarity of LiBr. This is illustrated below:
Molarity is defined as mole per unit litre of the solution. Mathematically, it is represented as:
Molarity = mole /Volume
Mole of LiBr = 1.126 mole
Volume = 1 L
Molarity of LiBr =?
Molarity of LiBr = 1.126 mole /1 L
Molarity of LiBr = 1.126 M
