<u> electrical energy to chemical energy</u>
Answer:Write and balance the equation
4Fe + 3O2 -> 2Fe2O3
0.32 mol Fe x 2 mol Fe2O3 / 4 mol Fe =
0.16 mol of Fe2O3
Explanation:
Answer:
Mean rate of reaction produced = 0.533 g/sec (approx.)
Explanation:
Given:
Reaction produced = 1.6 gram
Time taken = 30 sec
Find:
Mean rate of reaction produced
Computation:
Mean rate of reaction produced = Reaction produced / Time taken
Mean rate of reaction produced = 1.6 / 30
Mean rate of reaction produced = 0.533 g/sec (approx.)
The combination of seatbelts and airbags can reduce the risk of death in a collision by up to 80%.
The seatbelts help to keep the person in one position and prevent impact with the vehicle as the vehicle comes to a sudden stop. Moreover, the airbag increases the time of collision to reduce the impact experienced by the person. An increased time of collision greatly reduces the damage that is done to the body.
Answer:
Molecules of matter such as liquid, gas and solid still move even if the energy is transferred because it isn't a hundred percent. There is still energy and the time it took to transfer that said energy would have changed its state of matter.
Explanation:
Solid -the molecules are tight together. (touching)
Liquid - the molecules are close but not touching about mid way(not to far not to close)
Gas- the molecules in gasses are far apart.
It almost always goes from solid to liquid to gas. but in extreme conditions it could be different.
