Answer: The force of attraction present between the solids depends on the type of solid.
Explanation:
For e.g. if solid is ionic solid, then the ionic forces hold on the solid molecules. And these forces hold together and form solid. When it comes to hydrogen bonding stronger the hydrogen bonding, more together the molecules and it become solid.
The Correct answer is Carbon dioxide CO2.
The Explanation:
according to the diagram:
we can see that the arrows which going to A are from:
1- respirition of the tree . and the CO2 gas is the result and produced gas from respiration.
2- The Combustion went from Home : and the CO2 gas is also the produced gas from the combustion process.
∴ (A) refers to CO2 (carbon dioxide) gas.
The answer is B. Unsaturated hydrocarbons will be hydrocarbons that have twofold or triple covalent securities between neighboring carbon particles. Those with no less than one carbon-to-carbon twofold bond are called alkenes and those with no less than one carbon-to-carbon triple bond are called alkynes.
