100 M
1.6 M
0.626 M
0.01 M
Which solution is more concentrated?
Solution 1:
500 mL of water
100 g of salt
Solution 2:
500 mL of water
90 g of salt
Solution 1
Solution 2
They have the same concentration
I have no idea
Since "like dissolves like", water and oil will not mix because
both of them are polar
both of them are nonpolar
oil is polar and water is nonpolar
oil is nonpolar and water is polar
A scientists measures the amount of dissolved oxygen in samples with 4 different temperatures. All other variables are the same. Which of the following temperatures would have the highest concentration of dissolved oxygen?
41 degrees Celsius
34 degrees Celsius
22 degrees Celsius
10 degrees Celsius
As pressure increases in water
gases are less able to dissolve
gases are more able to dissolve
gases are less able to stay dissolved
What is shown in the picture?
dissociation
solvation/hydration
both dissociation and solvation/hydration
neither dissociation nor solvation/hydration
Hydrochloric acid (HCl) and acetic acid (HC2H3O2) are both acids. HCl completely dissociates in water, while HC2H3O2 does not. Which of the following statements best describes these two acids?
HCl is a weak acid, HC2H3O2 is a weak acid.
HCl is a strong acid, HC2H3O2 is a strong acid.
HCl is a strong acid, HC2H3O2 is a weak acid.
HCl is a weak acid, HC2H3O2 is a strong acid.
Which list of pHs are in order of increasing H+ ions?
6, 9, 12
9, 12, 6
12, 9, 6
9, 6, 12
How does the concentration of hydrogen ions compare to the concentration of hydroxide ions if a solution has a pH of 7?
H>OH
OH>H
H= OH
Zn(OH)2 + HNO3 ---> H2O + Zn(NO3)2
Complete the following reaction:
HCl + Mg(OH)2 -->
MgCl2 + H2O
Mg +H2O
MgCl2 + H2
MgCl2 + H2O + CO2
Complete the following reaction:
HNO3 + Ca(OH)2 -->
Ca(NO3)2 + H2O
Ca +H2O
Ca(NO3)2 + H2
Ca(NO3)2 + H2O + CO2
the more H+ ions the
stronger the acid
weaker the acid
it neutralizes
The picture below shows the relative concentrations of H+ and OH- in a solution. Is the solution an acid or a base?
