The statement that best describes the difference is ; The substance with the lower pH has 1000 times as many hydrogen ions per volume of water. ( D )
Given that the substance have pH ; 3 and 6
To prove the statement above we will make use of the pH formula
pH = -log(H⁺)
<u>for substance with </u><u>pH = 3</u><u> </u>
3 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻³
<u>for substance with </u><u>pH = 6</u>
6 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻⁶
Hence we can state that the substance with the lower pH has 1000 times as many hydrogen ions per volume of water

Answer:
A) a single variable
Explanation:
An appropriately designed experiment usually involves only one independent variable. This allows the scientist to truly determine whether the variable manipulated is what had an effect on the subject. You may test more than one variable, but this is usually done or experimented separately, or one at a time.
Answer:
Carbon nanotubes (CNTs) are a virtually ideal reinforcing agent due to extremely high aspect ratios and ultra high strengths. It is evident from contemporary research that utilization of CNT in producing new cement-based composite materials has a great potential.
Answer B, cause there is no BB there is only 2Bb and there is only 2bb
