Answer:
0.02 tons of NO produced when 4 tons of coal is burned
Explanation:
From the given,
Chemical formula of coal =
Molecular mass of coal =
Let’s calculate the mass of nitrogen in coal
Amount of coal burnt = 4tons
Amount of NO produced by burning 4tons =
This nitrogen is converted into NO by reacting with atmospheric oxygen.
Answer:
since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
