Answer:
CH3OH > CH3Cl > CH4
Explanation:
The boiling point of a compound depends on the nature and magnitude of intermolecular forces acting between its molecules.
Methanol contains the -OH group, hence hydrogen bonds are dominant intermolecular forces in the compound. Presence of hydrogen bonds increases the boiling point of a substance, hence methanol has the highest boiling point followed by chloromethane which has dipole-dipole interaction as dominant intermolecular forces and methane having only weak dispersion forces as dominant intermolecular forces.
Sulfur is the answer!
others are metalloid!
Explanation:
Hydrogen peroxide (H2O2) when decomposes forms water and oxygen in a reaction as shown below
However, this reaction is not completely balanced as number of oxygen atoms on reactant and product sides are not same
So, the complete balance equation looks like
NaHCO3 is the answer for the query
<u>Answer:</u>
<em>5 molecules of oxygen will be present
</em>
<u>Explanation:</u>
<em>In this reaction combustion is taking place hence there must be presence of oxygen in it.
</em>
We don't know the initial amount of carbon molecules in hydrogen molecules present hence the equation goes:-
Mass of fuel 16.74 grams, Mass of carbon dioxide is 1198 gram and water is 0.0654 remaining mass of fuel is 16.70 g. Hence amount of fuel used up is 0.04 gram
<em></em>
<em>Weight of products is 0.1852 and weight of oxygen is 0.1452
</em>
<em>No of molecules will be molecules
