Answer:
-6.4x10⁻¹⁹ C
Explanation:
The elementary charge of one electron is -1.60x10⁻¹⁹C, so each electron has its charge, and a sample with more than one electrons will have a multiple of its charge, which is proportional to the number of electrons. So, if the oil droplet had 4 electrons, thus the charge will be four times the elementary charge:
4*(-1.60x10⁻¹⁹) C = -6.4x10⁻¹⁹ C
The atomic number is the numbers of protons
Answer:
B. More reactant is added.
Explanation:
The question basically asks at which condition would the forward reaction be favoured.
The law of equilibrium states when a system at equilibrium is disturbed by, it would annul that change. In order to increase the forward reaction, more of the reactant should be added. In order to annul this change, the system would have to favour the reaction that deals with reducing the amount of reactant added.
The correct option is;
B. More reactant is added.
Answer:
Answer and Explanation: In this reaction ammonium sulfate reacts with potassium hydroxide to give aqueous potassium sulfate, gaseous ammonia, and liquid water as the products. This is essentially an acid-base reaction where the ammonium ion is donating a hydrogen ion to the hydroxide ion from the potassium hydroxide.
