The molecular compound in the given statement is CH₆N₂.

<h3>What defines a molecular compound?</h3>

Chemical compositions of molecules that make up molecular compounds reflect the number of elements that are really bound together within the molecule. Due to the sides and angles of a atoms' links to one another, the complex has a certain structure.

<h3>Briefing:</h3>

Consider 140.22 g/mol of compound

Carbon = 140.22 * 51.38/100

Carbon = 72 gm = 1 mol

Hydrogen = 140.22 * 8.64/100

Hydrogen = 12 gm = 6  mol

Nitrogen  = 140.22 * 39.97/100

Nitrogen  = 56 gm = 2 mol

The molecular compound is CH₆N₂.

Is the law of conservative mass observed in this equation CaCO3 + 2HCI --&gt;CaCI2 +H2O + CO2
pychu [463]

Answer:

The law is observed in the given equation.

Explanation:

CaCO₃ + 2HCI → CaCI₂ +H₂O + CO₂

In order to find out if the law of conservative mass is followed, we need to <u>count how many atoms of each element are there in both sides of the equation</u>:

  • Ca ⇒ 1 on the left, 1 on the right.
  • C ⇒ 1 on the left, 1 on the right.
  • O ⇒ 3 on the left, 3 on the right.
  • H ⇒ 2 on the left, 2 on the right.
  • Cl ⇒ 2 on the left, 2 on the right.

As the numbers for all elements involved are the same, the law is observed in the given equation.

1) According to Bohr's model of the atom, in which orbitals do electrons have the most energy?
Alex Ar [27]

The orbitals closest to the nucleus is the orbital wih the lowest energy. This is according to the basic rules stating that the energy of the shells as its principal quantum number increases, also increases. Thus the answer in 1 is B. Valence electrons are found in the outermost electron shell, on the other hand.
