Question

question 21 1 pts determine the name for cl₂o. chlorine (i) oxide chlorine oxide chlorate dichlorine monoxide chlorine (ii) oxide question 22 1 pts which formula/name pair is incorrect? mg₃n₂ / magnesium nitrite mn(no₃)₂ / manganese(ii) nitrate mg(no₃)₂ / magnesium nitrate mn(no₂)₂ / manganese(ii) nitrite

Explanation:

For Question 21, in binary covalent compounds, prefixes are used to denote the number of atoms of each element. There are two chlorine atoms and one oxygen atom in \(Cl_2O\), so it is named dichlorine monoxide. For Question 22, \(Mg_3N_2\) is magnesium nitride, not magnesium nitrite. Nitrite has the poly - atomic ion \(NO_2^-\) and nitride has the ion \(N^{3 -}\).

Answer:

Question 21: D. dichlorine monoxide
Question 22: A. \(Mg_3N_2\) / magnesium nitrite
