Answer:
A polar bond is one where the charge distribution between the two atoms in the bond is unequal. A polar molecule is one where the charge distribution around the molecule is not symmetric. It results from having polar bonds and also a molecular structure where the bond polarities do not cancel.
Explanation:
Answer :
Explanation : To find density, we can use the formula as given below;
density ρ =
Here, we have the mass as 89.6 g and the volume is ,
on calculating we get,
This means that the density of the copper sample is
Answer: A car rolling down a hill
Explanation: because kinetic energy is the force of some being pulled or pushed
Answer:
The volume of base was required for the titration is 13,53mL
Explanation:
In a titration of an acid (HX) with a base (YOH), the reaction of neutralization is:
HX + YOH → YX + H₂O
In the burette you are adding base until all HX reacts. The addition of base is in volume.
If in the beginnig, the volume that you read of base is 2,94mL and at the endpoint you read a volume of 16,47mL. The volume you spent in the titration that is the same volume of base you required for the titration is:
16,47mL - 2,94mL = <em>13,53mL</em>
