30 kg m/s
momentum = mass x velocity = 10 x 3 m/s =30 kg m/s

Answer:
D = m/V
Explanation:
Density represents the following ratio:
Density (D) = mass (m) / volume (V)
In this formula, the volume is being divided from the mass. The typical units for mass is grams and the unit for volume is milliliters.
Answer:
The equilibrium will shift to the right.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
For the reaction: <em>CH₄ + NH₃ + 1.5O₂ ⇄ HCN + 3H₂O.</em>
<em></em>
Adding NH₃ to the reaction:
- Adding NH₃ will increase the concentration of the reactants side, so the reaction will be shifted to the right (products) side to suppress the increase in the concentration of NH₃.
