Answer:
The answer to your question is true.
Explanation:
Carbons atoms have 4 valence electrons so they can form a great variety of bonds, like single bonds, double bonds and triple bonds.
single bond = C - C
double bonds = C = C
triple bonds = C ≡ C
Answer : If any atom has more electrons than one energy level can hold, then automatically the electron is accommodated in the next energy level (shell). The remaining extra electrons starts to fill the next energy level. This produces the valency of that particular atom.
Answer: Lewis dot structures aren't drawn for ionic compounds, such as MgCl2. Because there aren't any shared electron pairs in an ionic compound. Lewis structure are only drawn for molecular compounds, atoms, or some individual ions. If we want to visualize a chloride ion (Cl -), it's Lewis structure will show Cl with complete octet.

It is to be assumed that the unit of the given concentration is in molarity. To determine the number of moles given molarity and volume, we use the equation,
m = (M)(V)
volume should be in liters. Substituting the known values,
m = (0.350)(0.40 L)
m = 0.14 mols
Then, multiply the number of moles by the molar mass of KOH which is equal to 56.1056 g/mol.
mass = (0.14 mols)(56.1056 g/mol)
mass = 7.855 grams
Answer: 7.855 grams
Answer:
they both have to do with proportions
