Answer:
Li
Explanation:
It's on the periodic table.
Answer: Option (d) is the correct answer.
Explanation:
Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.
So, when thermal energy is added to an object then kinetic energy within its molecules will also increase. As a result, temperature of the object will also increase due to increase in number of collisions between the molecules.
Therefore, we can conclude that the statement energy that is associated with temperature, describes thermal energy.
First, take the molar mass of B (10.81g) and divide the value you've been given by the molar mass to get moles (5.4 / 10.81). So you have .5 moles of B and then you need to convert that to atoms. To do that you must use the constant 6.022X10^23 atoms per mole. Take your moles and multiply it by that constant. Your final answer should be (3.01X10^23) atoms.

Plants can adapt to their environment for example algae is soft and can survive being moved or broken this is perfect for living on top of water were animals often swim and shake the surface.
