V = 28,42 mL = 0,02 L
molar mass C3H6O = 58
n C3H6O
= V / 22,4
= 0,02 / 22,4
= 0,0009 mol
mass
= n x molar mass
= 0,0009 x 58
= 0,0522 gr
Group 2 because the outer electrons ( also known as valence electrons) are 2 and that’s how we know which group it is in
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal
Answer:
See figure 1
Explanation:
In this question, we have to remember that each <u>carbon has 4 electrons</u> and each <u>hydrogen has 1 electron</u>. Additionally, the structure proposed have to have <u>8 electrons for each atom</u> <u>(except hydrogen)</u>. With this in mind, we need to have a <u>double bond</u> between the carbons, because in this arrangement each carbon would have 8 electrons <u>(octet rule)</u>.

Answer:
The answer to your question is 200 g
Explanation:
Data
mass of water = ?
mass of NaOH = 4 g
concentration = 2 %
Formula
% mass = mass of solute/mass of solution x 100
-Solve for mass of solution
mass of solution = mass of solute / % mass x 100
-Substitution
mass of solution = 4 / 2 x 100
-Simplification
mass of solution = 2 x 100
-Result
mass of solution = 200 g
