From the density of ethanol given, the number of pounds of ethanol in the drum will be 46.099 pounds.
<h3>How to calculate density</h3>
Density of ethanol = 0.789/cm³
1 gallon = 3785.4ml
Volume of ethanol = 7 gallons = 7 × 3785.4ml = 26497.8ml
Mass of ethanol = Volume × Density.
= 26497.8 × 0.789
= 20906.764g
Since 1g = 0.002205 pounds, the mass of ethanol will be:
= 20906.764 × 0.002205
= 46.099 pounds.

Answer:
False. The balanced equation should be
2KClO3-->2KCl + 3O2
it is a decomposition reaction.
Answer:
See explanation
Explanation:
I know that we usually associate the sp3 hybridization to the tetrahedral shape. This is common in molecules such as CH4. So it may sound somewhat strange that NH3 molecule has an sp3 hybridized nitrogen atom and a trigonal pyramidal geometry.
Let us recall that the central nitrogen atom in NH3 has a lone pair of electrons. These lone pairs causes more repulsion than bond pairs. As a result of the presence of this lone pair, the bond angle in the NH3 molecule is distorted away from the expected 109.7 degrees in tetrahedral geometry and the bonding groups are now arranged in a trigonal pyramidal geometry(with bond angle less than 109.7 degrees) to minimize electron pair repulsions.
When 1-bromo propane is reacted with sodium metal, the propane and sodium bromide are formed.
- Propane and sodium bromide are produced when the 1-bromo propane is reacted with sodium metal.
- The Bromine which is present in the 2-bromopropane is removed through hydrogenation and combines with the sodium metal which results in the production of propane and sodium bromide.
- So we can conclude that propane and sodium bromide are produced when the 1-bromo propane is reacted with sodium metal.
