Answer:
- <u>option </u><u><em>B. Lose 1.</em></u>
Explanation:
To determine the number of<em> electrons that a single hydrogen gains or loses </em>you need to realize that the chemical reaction is an oxidation-reduction (redox) reaction and state the changes in the oxidation states.
The substance that gains electrons is being reduced, reducing its oxidation number, and the substance that lose electrons is being oxidized, increasing its oxidation state.
<u>1) State the oxidation state of hydrogen atoms in the rectant side:</u>
- H₂: the oxidation state of any element in its atomic or molecular form is zero. That is indicated as a superscript to the right of the chemical symbol: H₂⁰
<u>2) State the oxidation state of the hydrogen atoms in the product side:</u>
- H₂O: the rule says that the oxidation state of oxygen, when combined with other elements, except in the case of peroxides, is -2.
Hence, in order to the molecule H₂O be neutral, the total charge contributed by the two atoms of hydrogen must be + 2: +2 - 2 = 0.
Since there are two hydrogen atoms, each contributes +2 / 2 = +1 charge.
<u>3) Conclusion:</u>
Every atom of hydrogen changes from a 0 oxidation number to a +1 oxidation number, which, in turn, means that every hydrogen atom loses one electron.
Thus, the answer is, the option <em>B. Lose 1.</em>
Explanation:
protons.
An acid can also be thought of as a chemical that can neutralize a base. Similarly, a base can neutralize an acid.
Acids turn litmus paper red, while bases make litmus paper turn blue.
Some examples of acids are sulfuric acid, hydrochloric acid, nitric acid, and so on. Some examples of bases are sodium hydroxide, potassium hydroxide, and so on.
Acids generally taste sour, while bases have a bitter taste.
Alkalis are the bases that are water-soluble, which means that they dissolve in water. In other words, not all bases are water-soluble, and only the water-soluble bases are known as alkalis. An example of an alkali is sodium hydroxide. It is a base because it can neutralize an acid, and because it is water-soluble, it is an alkali. An example of a base that is not alkali is copper oxide. This chemical can neutralize an acid, but it is insoluble in water.
In other words, all alkali are bases but not all bases are alkalis.
Also, an alkali has a hydroxide group, while a base has an oxide group in it.
Answer:
Is there a picture To go with this?
Explanation:
First structure is CH₃-CH₃. It is an alkane with two carbon atoms hence it is called ethane.
Second structure is CH₃-CH₂-CH₂-CH₃. It is an alkane with four carbon atoms hence it is called butane.
Third structure is CH₄. It is an alkane with one carbon atom hence it is called methane.
Fourth structure is CH₃-CH₂-CH₃. It is an alkane with three carbon atoms hence it is called propane.
