Answer:
I think the answer might be D. but im not 100 percent sure
Explanation:
Given data:
Volume of HCl = 14.22 ml
Molarity of HCl = 2.97 M
mmoles of HCl = 14.22 * 2.97 = 42.2 mmoles
Volume of NaOH = 5.00 ml
Molarity of NaOH = 0.1055 M
mmoles of NaOH = 5.00 *.1055 = 0.5275 mmoles
Since HCl and NaOH combine in a 1:1 ratio
# moles of NaOH = # moles of excess HCl that is neutralized = 0.5275 moles
Now, the total moles of HCl taken = # mmoles HCl neutralized by antacid + # mmoles of excess HCl
42.2 = mmoles HCl neutralized by antacid + 0.5275
Therefore,
mmoles of HCl neutralized by antacid = 42.2 - 0.5275 = 41.6725 mmoles = 41.7 mmoles
Answer:
The final pressure of a gas is inversely proportional to the volume change and directly proportional to temperature
Explanation:
Given

Required
Interpret

Multiply both sides by T1


Divide both sides by V1


This can be rewritten as:

In the above expression; k is a constant of proportionality.
So, the equation can be written as variation as follows:

To interpret:
<em>P varies directly to T (the numerator) and inversely to V (the denominator).</em>
