Answer:
2HCI + Na2S ----> H2S + 2NaCl
Explanation:
For a balanced chemical equation, the number of moles of atoms on the reaction side must equal the number of moles of atoms on the product side, in accordance with the law of conservation of mass.
The correct answer is:
2HCI + Na2S ----> H2S + 2NaCl
Since it has equal number of moles of each atom on both sides of the equation: 2 atoms each of hydrogen, chlorine, and sodium on both sides of the equation as well as 1 atom of sulphur on both sides of the equation.
Answer:
True
Explanation:
Pi bonds are formed using p orbitals. Atoms that have p orbitals have 3 of them. In an sp² hybridized atom, only 2 of the 3 p orbitals are being used in the sp² orbitals, leaving one p orbital free for pi bonding. Therefore, only one pi bond can be formed to an sp² hybridized atom.
