Answer:
The reaction is exothermic
The temperature of the water bath goes up
Explanation:
An exothermic reaction is one in which energy flows out of the reaction system.
In this case, the system is the reaction vessel while the surrounding is the water bath. We see in the question that 300.1J of heat flows out of the system during the reaction. This is heat lost to the surroundings showing that the reaction is exothermic.
As energy is lost to the surroundings, the temperature of the water bath rises accordingly.
Answer:
The center of the atom contains the nucleus so yes
Explanation:
Answer:
Its particles are evenly distributed.
Explanation:
Solutions are homogenous mixtures of solutes and solvents. In a solution the solute particles are evenly distributed in the solvent.
Here are some characteristics of solutions:
- The size of the particles is small
- The particles do not settle on standing
- The particles pass through ordinary filter papers
- The particles pass through permeable membranes
- The particles are not visible with microscope or the naked eyes.
- They are clear and may have a color.
