<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
Double displacement reaction is defined as the reaction in which exchange of ions takes place.
The chemical equation for the reaction of hydrochloric acid and potassium sulfide follows:
By Stoichiometry of the reaction:
2 moles of hydrochloric acid reacts with 1 mole of potassium sulfide to produce 2 moles of potassium chloride and 1 mole of hydrogen sulfide gas
Hence, the balanced chemical equation is written above.
The scientist should do the following to make sure that their scientific investigation is replicable is by having to have their studies, researches and experiments to be written down as this will serve as a basis and a way of having to have a solid proof of having the investigation or experiment to be conducted again or to be replicable.
Answer: A. The greater the pressure, the more of gas that will dissolve.
Explanation: Increasing pressure increases the solubility of gases. It has little effect on the solubility of liquids and solids.
Hello!
The light from the sun hits one side of the moon and doesn’t hit from the other side. So that’s how we view it on earth

Answer:
The correct answer is 1.
Explanation:
The metabolism of homocysteine produces a sulfur amino acid that is normally formed from methionine during the fulfillment of its function as a donor of methyl groups. Metabolic fate such as remethylation and transsulfuration, involving the enzymatic forms of the vitamins folacin, B12, and B6, gives rise to homocysteine and mixed disulfides including so-called protein-linked homocysteine, the main form circulating in plasma. B6 deficiency would have a direct impact on the metabolism of homocysteine to cysteine.
Have a nice day!
