Question

question 17 (1 point)
name the following covalent compounds
c₃h₈

question 18 (1 point)
name the following covalent compounds
n₂o₄

Explanation:

For \(C_3H_8\), it is an alkane. The general formula for alkanes is \(C_nH_{2n + 2}\). When \(n=3\), according to the naming rules of alkanes (using prefixes like 'prop -' for \(n = 3\)), it is propane.

For \(N_2O_4\), in covalent compound naming, we use prefixes to indicate the number of atoms. The prefix for \(2\) is 'di -' and for \(4\) is 'tetra -'. The first element is nitrogen and the second is oxygen (ending with '-ide'). So it is dinitrogen tetroxide.

Answer:

Propane; Dinitrogen tetroxide
