<span>Moles HClO4 = 0.02500 L x 0.723 M=0.0181
moles KOH = 0.0100 L x 0.273 M= 0.00273
total volume = 25.00 + 10.0 = 35.0 mL = 0.0350 L
moles H+ in excess = 0.0181 - 0.00273 =0.0154
[H+]= 0.0154 mol/ 0.0350 L=0.440 M</span>

Answer:True</h2>
Explanation:
Contact force is defined as the force a pair of objects experience when they are in contact.
Ex.normal force,friction.
Non-contact forces are defined as the forces a pair of objects experience even if they are not in contact.
Ex.electric force,magnetic force.
Given that a contact force exist between two interacting objects that physically contact each other. A non-contact force exist when two interacting objects are not in physical contact but can still influence each other.
So,the given statements are true.
