Explanation:
Answer:
120g Using Density Equation.
Explanation:
Density =mass/volume
We need to the solve for the mass.
Mass=Density * Volume
Mass= 2.40 g/ml * 50.0 ml = 120g
They must make sure that all things pointed out are fact, not opinion.
The answer is N2 + 3H2 yields 2NH3. The oxidation-reduction reaction means that there is electrons transfer during the reaction which means that the valence changed.
