Answer:
the first one is balanced.
Answer:
neutrons are inside the nucleus
Explanation:
The most significant contribution that added to Rutherford's discovery of a positive nucleus is that neutrons are also inside the nucleus.
- The discovery of neutrons as a nuclear particle was instrumental to Rutherford's discovery.
- Since during his experiment, the alpha particles were deflected partly, he suggested a massive nucleus made up of just protons.
- With the discovery of the neutron, the mass of the nucleus was enough to cause the deflection.
Answer: all other conditions equal, the rate evaporation of a contained liquid will be slower than the rate of evaporation of an uncontained liquid.
Justification:
1) The rate of evaporation increases as the surface area of the liquid (relative to the whole content) increases. This is, the greater the surface is the faster the evaporation.
2) That is so because the higher the surface of the liquid the more the number of particles in the liquid that are in contact with the surrounding air and so the more the particles will escape from the liquid to the air (which is what evaporation is).
3) A liquid contained will take the form of the container, so part of the liquid wil remain below the surface, while an uncontained liquid will spread all over the surface and so pratically all the liquid is in contact witht the air surrounding it.
When the sugar cubes are <span>placed in water, then, the mixture will be affected by stirring the water.
By stirring the water, the sugar cubes dissolve in water. The molecules of sugar cubes interact with water molecules in the jar. But when more sugar is added to the water, there comes a saturation point when no more sugar will be dissolved and it will settle down. Then, by raising the temperature the settled sugar will be dissolved too.</span>
