Answer:
See image attached for structure of CH3Br
Explanation:
A lewis structure structure is a representation of a covalent compound in which dots are used to show valence electrons, lone pairs and bonding electrons. The system was introduced by sir G.N Lewis in 1916 in his article titled 'Atom and Molecule'. They are also called dot electron diagrams of molecules. CH3Br molecule contains a total of fourteen electrons. Valence electrons are shown by dots around the atom of each element as clearly seen in the image attached.

Answer:
D.
Explanation:
I took this test as a freshman and this was the only question of 4 that I can remember
40.0mL(1 L/1000 mL) = 0.040 L
<span>then plug into the formula M = moles/liters </span>
<span>0.035 M = moles/ 0.040L </span>
<span>multipy both sides by 0.040L, and you get 0.0014 moles </span>
<span>so the answer is 1</span>
