Answer:
2, strong acid
Explanation:
Data obtained from the question. This includes:
[H+] = 0.01 M
pH =?
pH of a solution can be obtained by using the following formula:
pH = –Log [H+]
pH = –Log 0.01
pH = 2
The pH of a solution ranging between 0 and 6 is declared to be an acid solution. The smaller the pH value, the stronger the acid.
Since the pH of the above solution is 2, it means the solution is a strong acid.
Answer:
true
Explanation:
drought is a period of unusually persistent dry weather that persists long enough to cause serious problems such as crop damage and/or water supply shortages. The severity of the drought depends upon the degree of moisture deficiency, the duration, and the size of the affected area.
Answer:
107.5 amu
Explanation:
isotopes: fractional Wt Avg
isotopes: isotopic mass %Abundance abundance (amu)
X110 110 60 0.60 66.0
X105 105 30 0.30 31.5
<u> X100 100 10 0.10 10.0</u>
∑ atm mass contributions = 107.5 amu*
*amu = atomic mass units
Answer:
The concentration of the diluted solution is 3.75 M
Explanation:
Step 1: Data given
Volume of a stock solution = 75 mL = 0.075 L
The molarity of stock solution = 5.0 M
We add 25 mL, The total volume is 100 mL = 0.100 L
Step 2: Calculate the concentration of the diluted solution
C1*V1 = C2*V2
⇒with C1 = the initial concentration = 5.0 M
⇒with V1 = the initial volume = 0.075 L
⇒with C2 = the new concentration = TO BE DETERMINED
⇒with V2 = the diluted volume = 0.100 L
5.0 M * 0.075 L = C2 * 0.100L
C2 = (5.0M * 0.075 L) / 0.100 L
C2 = 3.75 M
The concentration of the diluted solution is 3.75 M
