Answer:
As mass increases the gravitational force increases
Explanation:
Things with mass gain a gravitational force, The bigger they are the more force, for example: the sun is the biggest so it pull us
Answer:
and 
Explanation:
The equation for the reaction is AgNO3(aq) + KCl(aq) ==> AgCl(s) + KNO3(aq)
With all the ions, it is
(aq) + 
(aq) + (aq) + 
(aq) ==> AgCl(s) +
and do not change, so they are the spectator ions and are removed
The ionic equation is:
(aq) + (aq) ==> AgCl(s)
Answer:
The answer to your question is pH = 1.45
Explanation:
Data
pH = ?
Volume 1 = 200 ml
[HCl] 1 = 0.025 M
Volume 2 = 150 ml
[HCl] 2 = 0.050 M
Process
1.- Calculate the number of moles of each solution
Solution 1
Molarity = moles / volume
-Solve for moles
moles = 0.025 x 0.2
result
moles = 0.005
Solution 2
moles = 0.050 x 0.15
-result
moles = 0.0075
2.- Sum up the number of moles
Total moles = 0.005 + 0.0075
= 0.0125
3.- Sum up the volume
total volume = 200 + 150
350 ml or 0.35 l
4.- Calculate the final concentration
Molarity = 0.0125 / 0.35
= 0.0357
5.- Calculate the pH
pH = -log [H⁺]
-Substitution
pH = -log[0.0357]
-Result
pH = 1.45
the first is hydroxide. I believe d is the second one but I'm not 100% positive so you may want to get a second opinion
