The purple roots of beetroot are eaten as a vegetable. I am assuming that they are talking about the actual veg.
Answer:
17g
Explanation:
4NH3 (g) + 502 (g) –> 4NO (g) + 6H20 (g)
Mass of O2 mole = 32g
Therefore 5O2 = 160g
Mass of NH3 mole = 17g
Therefore 4NH3 = 17 x 4 =68g
Required amount of NH3 = 68 x 40/160 = 17g
Assuming that the object started in the ground state, any object that has lost one or more electrons would have a positive change because there would be more protons than electrons present. Therefore, the positive charge of the protons would preside over the negative change of the electrons.
Hope this helps.
The most likely explanation for this observation is C. his car has turned on more pistons to provide the extra energy needed to accelerate.
When cruising, hybrid cars are able to employ electrical energy to drive the car. Moreover, even if a vehicle is not a hybrid, a greater amount of fuel is consumed when one accelerates because the vehicle has to generate a force larger than the force of air resistance in order for it to accelerate. This increased demand of force reduces the vehicle's fuel economy.
