Answer:
The 
of the clean compound is approximately 10.495.
Step-by-step explanation:
If the cleaning ion concentration of the cleaning compound is ![[H^{+}] = 3.2\times 10^{-11}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%20%3D%203.2%5Ctimes%2010%5E%7B-11%7D)
, then the , no unit, of the compound is:
![pH = -\log_{10} [H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-%5Clog_%7B10%7D%20%5BH%5E%7B%2B%7D%5D)
(1)
The of the clean compound is approximately 10.495.
Positive if it is an increase.
Does that help? Idrk what ur asking
Answer:
Solution given:
diameter=14cm
radius [r]=14/2=7cm
now
area of semi circle or shaded region: ½πr²=½(3.14*7²)=76.93cm²[approximately]
It would be D because if it’s the product that means times so 4xs=25
Answer:
v = 875
Step-by-step explanation:
0.01v + 0.09(8000-v) = 650
Multiply the parenthesis
0.01v + 720 - .09v = 650
Combine like terms
720 - 0.08v = 650
Add 0.08v to both sides
720 = 650 + 0.08v
Subtract 650 from both sides
70 = 0.08v
Divide by 0.08 on both sides
v = 875
Hope this helps :)
