The answer would be a tenfold increase<span>
The pH scale is calculated based on the concentration of H+ ion in the solution. The formula is using log10, so to decrease 1 unit from the scale it will be 10^1= 10 fold of increase. For 2 </span>unit, you will need 10^2= 100 fold of increase.
Answer:
a negative ion, and an isotope.
Explanation:
The perfect atom consists of an equal balance in all 3. If the neutrons are not even with the protons, it is an isotope since it is like another version of the so called (but not actually) 'perfect' atom. If there is more electrons, the charge is negative, making it an ion.
A) 4
pH=-log[H+]
pH=-log(10^-4)
B) Weaker
pH of orange juice=4
pH of coffee=5
An acid with pH of 4 is stronger than a pH of 5
C) 7, neither/neutral
pH of water=7
Answer:
B
Explanation:
Genetics,mutations over time
This is the answer because on biology you have all those kind of questions
