2zns(s)+3o2(g)—>2zno(s)+2so2(g)
Paha777 [63]

This is an example of displacement reaction

<u>Explanation:</u>

  • The chemical reaction in which the one element replaces the other element in a compound is called a displacement reaction. This reaction is also called a replacement reaction.

                                AB + C -----> AC +B

                        2ZnS + 3O2 -----> 2ZnO + 2SO2

  • This happens when A is more reactive than B and gives a stable product. Here the zinc sulfide compound reacts with the oxygen element to the stable product of zinc oxide and sulfur dioxide.
  • In short, the more reactive element displaces the less reactive element is called a displacement reaction.

What is the answer to this question?
lord [1]
The answer is D.

The atomic number stands for the number of protons in each element. The number of protons is what is unique to each element. The number of neutrons varies; this is what isotopes are. The number of protons being the atomic number explains why the atomic number is an identifying characteristic of each element.

Diphosphorus pentoxide(P2O5) reacts with water to form phosphoric acid, a major industrial acid. In the laboratory, the oxide is
Akimi4 [234]

Answer: The mass of 4.65\times 10^{22} molecules of phosphorus pentoxide is 20.5 g

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given molecules}}{\text {avogadro's number}}=\frac{4.65\times 10^{22}}{6.023\times 10^{23}}=0.0772moles

1 mole of P_2O_5 weigh =  283.9 g

Thus 0.0772 moles  of P_2O_5 weigh = \frac{283.9}{1}\times 0.0722=20.5g

Thus the mass of 4.65\times 10^{22} molecules of phosphorus pentoxide is 20.5 g
