Answer:
Explanation:
A. Ethanoic acid-acetic acid being weak acid dissocated weekly and turns solution to weakly acidic, ph will be between 4-7,
B. Hydrochloric acid - the solution would be acidic- with lots of H+ ions, Ph will be between 1-4,
C. Sodium chloride - solution prodcued netural Na+ and Cl- hence wont affect ph of solution will be equalt to 7.
D. Sodium hydrogen carbonate-NaHCO3 is weak base and the PH will be above 7,
hope these helps you to find your answer
The correct answer among the choices is the first option. The movement of the molecules inside a block of iron when it is heated is affected by the movement being faster as compared to the first conditions. Temperature is said to be directly proportional to kinetic energy which means as temperature increases, the kinetic energy also increases. Therefore, molecules now are moving faster.
Answer:
HNO3 is a strong acid
HCl is also a strong acid
NaCl is a salt so it is neither a strong acid nor a strong base
Ca(OH)3 is a strong base
