Answer:
The answer to your question is 71.22 g
Explanation:
Data
Density = 19.3 g/cm³
Volume = 0.00369
mass = ?
Formula
Density =
Solve for mass
mass = density x volume
Process
1.- Convert volume from liters to cubic centimeters
1 l ---------------- 1000 cm³
0.00369l --------- x
x = (0.00369 x 1000 ) / 1
x = 3.69 cm³
2.- Substitution
mass = 19.3 x 3.69
3.- Simplification and result
mass = 71.22 g
As we know that <span>Boron has 6 valence electrons
So it does not have to fill a complete octet. it just need two electrons
Thus B(CH3)3 will have only 3 electron domains, and it will constitute</span> a trigonal structure.

Answer:
The unbalanced chemical equation of propane combustion is
C₃H₈ (g) + O₂ (g) → CO₂(g) + H₂O(g)
Explanation:
Combustion is a type of chemical reaction in which there is the release of energy in the form of heat. This means that this reaction can be called exothermic.
When propane reacts with oxygen present in the air, it releases a high amount of heat. If the reaction is fully completed, the products are carbon dioxide and water vapor.
