Object one will float because the mass and volume are lighter than object two. Object one also has a smaller surface area.
Answer:
Refluxing allows thermally unstable reactants to react faster without decomposition.
Explanation:
Reflux is an experimental laboratory technique, used to produce heating reactions that take place at temperatures higher than room temperature and where it is better to maintain a constant volume in the reaction. By means of this mechanism, it is possible to avoid losing solvent in the course of the process, and therefore, without releasing it into the atmosphere. This is used to heat mixtures for a long time at a certain temperature. As the temperature increases, the reactant particles collide more times and, because they have more energy, there are more particles that exceed the activation energy, which leads to more effective collisions and a higher reaction speed.
Answer: density equals 3 g/mL
Step by step explanation:
D=m/v
D=45/15
D=3
the answer is independent
The majority of metals are found in ores.
But a few such as copper, gold, platinum, and silver frequently occur in the free state because they do not readily react with other elements.
