Missing question: What is the total combined mass of carbon dioxide and water that is produced?
Chemical reaction: gasoline + O₂ → CO₂ + H₂O.
For this question use mass conservation law (mass of products is equal to mass of reagents): m(reactants) = m(products of reaction).
m(gasoline + oxygen) = m(carbon(IV) oxide + water).
m(carbon(IV) oxide + water) = 20 kg + 83 kg = 103 kg.
Electron transfers between energy levels.
<h3>Explanation</h3>
An atom contains an infinite number of energy levels. An electron can exist within any one of them, but not in between. Electron can move from one level to another. However, those levels differ in energy. Energy has to conserve.
- An electron loses energy when it moves to a level of lower energy. The energy is released as radiation. The frequency of the radiation depends on the energy difference. Those radiations combine to produce an emission spectrum.
- An electron gains energy when it moves to a level of higher energy. This transfer happens only if there's an external source of energy. For example, directing a beam of white light on the atom. The beam of light would excite the electron. Again, the frequency of the radiation depends on the energy difference. Only frequencies that corresponds to transfer will be absorbed. Those radiation will eventually be released in all directions. As a result, strength of some of the radiations will be weakened. A continuous spectrum with those frequencies weakened is an absorption spectrum.
Answer:
East
Explanation:
Given Newton's third law of motion; "Action and reaction are equal and opposite", when a student jumps off a sled toward the west after it stops at the bottom of an icy hill, the sled will move in the East direction.
This is because, the force exerted on the sled is a reaction force and is opposite in direction to the force that thrusts the boy westward though equal in magnitude with the former.
