Question

write the name for h₂o. *
your answer

what is the molar mass of luminol (c₈h₇n₃o₂)? *
your answer

balance the following equation: *

Explanation:

Step1: Name of \(H_2O\)

\(H_2O\) is a common compound. By chemical naming rules, it is named water.

Step2: Molar mass of luminol (\(C_8H_7N_3O_2\))

The molar mass of an element is: \(M(C)=12\ g/mol\), \(M(H) = 1\ g/mol\), \(M(N)=14\ g/mol\), \(M(O)=16\ g/mol\).
For \(C_8H_7N_3O_2\), the molar mass \(M\) is calculated as:

Answer:

1. Water
2. \(177\ g/mol\)
