Answer:
i think its C, but im not 100% sure. if not c, then D, but C sounds more right.
Explanation:
everything else sounds like sure fire sighs of a chem change. good luck
Answer:
pH = 7.01
Explanation:
The pH can be calculated using the formula:
pH = -log[H⁺]
In this formula, [H⁺] represents the concentration of H⁺. Since you have been given this value, you can easily find the pH.
pH = -log[H⁺]
pH = -log[9.71 x 10⁻⁸]
pH = 7.01
The total mole number of solutes will not change. So it is 25 * 10^-3 *4.525 mole. And the final volume is 25+112 = 137 mL. So the resulting concentration is mole number / volume=0.8257 M.
Answer:
no dont worry its in decimal point
anything after the point is considered as not to the fullest
Resistance is directly proportional to voltage so when you increase Voltage resistance will also increase in order to keep the rate of flow of charge (current) constant
Hope this helps!
