Answer:
pH value of a solution depends on the concentration of hydrogen ions
(pH = -log[H+(aq)].
Hydrochloric acid is a strong acid, while ethanoic acid is a weak acid. Strong acids ionize completely in water (to give ions which includes H+(aq)), while weak acids only ionize partially in water.
Therefore, even if both hydrochloric acid and ethanoic acid are monobasic acids (each molecule can ionize completely to give 1 hydrogen ion), since hydrochloric acid ionizes completely in water and ethanoic acid does not ionize completely, the concentration of hydrogen ions in hydrochloric acid is higher than that of ethanoic acid, leading to a lower pH value for hydrochloric acid, while higher for ethanoic acid.
Answer:
Chloroplasts
Explanation:
Chloroplasts purpose are to take the energy from the Sun's light and turn it into food for the plant.
Answer:
Disnt make sense show me question
The balanced chemical equation is:
2Fe+3H2O=Fe2O3+3H2
We are given the amount of water to be used in the reaction. This will be the starting point for the calculations.
3 mol H2O ( 1 mol Fe2O3 / 3 mol H2O ) = 1 mol Fe2O3
Therefore, the correct answer is option B.
Actually the rate of reaction can be shown as:
R = k [A]^x [B]^y
The rate of reaction can be determined with help of order of reaction which is an experimental quantity and the order can be determined experimentally.
Hence for the rate of reaction crystall violet depends on order of crystall violet and mostly the order of crystall violet is 1 and thus on doubling the concentration, the rate of reaction gets doubles.
