NARA [144]2 years ago
6 0

Answer:

\boxed {\boxed {\sf C. \ More \ protons \ are \ present \ in \ the \ atomic \ nucleus}}

Explanation:

First, let's define <u>atomic number</u>.

    ⇒ The number of <u>protons </u>in an atom.

    ⇒ This number determines the identity and properties of the atom

So, atomic number relates to protons. There is an increase in atomic number, so there must be <u>more</u> protons in the atom. We can eliminate choices A and B, because they pertain to electrons.

We are left with choices C and D. The difference between them is the location of the protons.

Protons are part of the <u>nucleus </u>of the atom: the dense, central region of the atom comprised of nucleons: protons and neutrons.

Electrons, not protons, orbit the nucleus, so  D is not correct.

We are left with choice C: <u>more protons are present in the atomic nucleus </u>

azamat
<h3>Answer:</h3>

True, the reaction given is an example of a synthesis reaction

<h3>Explanation:</h3>
  • Synthesis reactions are reactions where two or more substances combine to form a single compound.
  • The reaction 2NO(g) + O₂(g) → 2NO₂(g) is an example of a synthesis reaction.

Other types of chemical reactions may include;

  • Decomposition reaction in which a compound is broken down into smaller compounds or individual elements.
  • Replacement reaction where reactive elements replace other less reactive elements in their salts.
  • Precipitation reactions in which soluble salts reacts to form a precipitate and a soluble salt as a result of exchange of anions and cations.

PLEASE HELP <br> What is the pH of a weak acid solution that has an [H+] of 2.1 × 10^–6 M
sveticcg [70]

Answer:

pH ( potential Hydrogen ) is a negative logarithm of molar concentration of hydrogen ions.

pH =  -  log[H {}^{ + } ]

therefore:

pH =  -   log(2.1 \times  {10}^{ - 6} )  \\ { \boxed{pH = 5.68}}
