Answer:

Explanation:
Hello there!
In this case, since we need to dilute the 1.75-M HCl, and the total number of moles remain unchanged, we can write:

And in terms of volume and concentration:

Thus, we can solve for the volume of the concentrated HCl as shown below:

Therefore, we plug in the data to get:

Best regards!
Answer:
The pressure of a given amount of gas is directly proportional to its absolute temperature, provided that the volume does not change (Amontons's law). ... The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law).
Answer:Density (ρ) = 7.1538461538462 kilo
Explanation:ρ =
m
V
=
9.3 gram
1.3 liter
= 7.1538461538462 gram/liter
= 7.1538461538462 kilogram/cubic meter
Answer: If two positive charges interact, their forces are directed against each other. The two charges repel each other.
Explanation: The same occurs with two negative charges, because their respective forces also act in opposite directions.) The electric field and resulting forces produced by two electrical charges of the same polarity.
Good luck luv.
