8.5L H2O (1 mol H2O/22.4L)=.37946 mol H2O
.3796 mol H2O(1 mol CH4/2 mol H2O)=.18973 mol CH4
.18973 mol CH4(22.4L/1mol CH4)=4.25L CH4 gas
Answer:
Explanation:
In electrophilic aromatic substitution, the substituent(s) that favors electrophilic attack is said to be ortho or para to the substituent. Meta directors are deactivators. Altogether, these directors have an integral role to play in the success and regioselectivity of electrophilic aromatic substitution reactions.
From the information given: The;
Strongly deactivating meta- director ⇒ NO₂ (nitro group)
Moderately deactivating meta- director ⇒ CN (cyano group)
Strongly activating ortho-/para- director ⇒ OH (hydroxy; group)
Weakly deactivating ortho-/para- director ⇒ -X (halide group)
Weakly activating ortho-/para- director ⇒ - Ph (phenyl group)
The net ionic equation is written as H^+(aq) + OH^-(aq) -------> H2O(l)
<h3>What is the net ionic equation?</h3>
The term net ionic equation refers to the equation that shows the ions that underwent a change in the reaction. We have to note that the reaction species here must be ionic species which are able to dissociate into ions in solutions.
Now the first step is to put down the molecular equation. The molecular equation shows the reaction of the compounds as follows;
HCI (aq) + NaOH (ag)-> NaCI (aq) +H2O(l)
Next, we put own the complete ionic reaction equation as follows;
H^+(aq) + Cl^-(aq) + Na^+(aq) + OH^-(aq) -------> Na^+(aq) + + Cl^-(aq) + H2O(l)
Next we have the net ionic equation;
H^+(aq) + OH^-(aq) -------> H2O(l)

Answer: The type of molecule that supports a tree's tall structure is A. polysaccharide.
Explanation:
Polysaccharides are macromolecules consisting of many monosaccharide units. The Oxygen- hydrogen groups that make up the monomers such as glucose can form hydrogen bonds with cellulose molecules. These hydrogen bonds formed, allows for the cellulose strands to form fibres, providing trees and other plants.
Therefore, polysaccharides are molecules that supports a tree's tall structure.
