Enter the chemical equation 2H+(aq)+S2−(aq)→H2S(g). Express your answer as a chemical equation:
The skill that must be know in chemistry is writing the chemical equations, because these equations are the representations of chemical reactions between substances. The chemical equation consists of substances reacting on the left side and the products formed on the right side, with a right arrow inserted to show a chemical reaction taking place. The phases of the substances are included by writing them as subscripts contained in a parenthesis.
For chemical reactions involving ions, the superscripts are used and the number is usually placed before the charge (i.e. 2+, not +2).
For the given chemical reaction, the complete chemical equation including the phases given by:
Sulfur is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Whereas Hydrogen sulfide
is a colorless chalcogen hydride gas with the characteristic is very poisonous, corrosive, and flammable. Hydrogen
is the most abundant chemical substance in the Universe

Answer : The complete chemical equation is,
Explanation :
As we know that, in a chemical equation the reacting species present on left side and the product formed present on right side and a right arrow inserted between the reactants and product that show a chemical reaction taking place.
In the chemical reaction, the phases of the substances are also included and subscripts and superscripts are also used for the numbers.
For the given chemical reaction, the balanced chemical equation including the phases, is given by:
Answer:
The tissue cells
Explanation:
I think you mean this
It all starts from Carbondioxide. This Carbondioxide is dissolved in the blood and taken by red blood cell and converted into carbonic acid. It then dissociates to form a bicarbonate ion and a hydrogen ion
This <--> means that the whole process is reversible. It is a buffer system to maintain the pH in the blood and duodenum. And also to support proper metabolic function.
Answer:
b
Explanation:
The reaction that is not a displacement reaction from all the options is
In a displacement reaction, a part of one of the reactants is replaced by another reactant. In single displacement reactions, one of the reactants completely displaces and replaces part of another reactant. In double displacement reaction, cations and anions in the reactants switch partners to form products.
<em>Options a, c, d, and e involves the displacement of a part of one of the reactants by another reactant while option b does not.</em>
Correct option = b.
