Answer:
The required mass is 22.04 g
Explanation:
We know,
Atomic mass of Co= 58g.
Now,
1 mole Co = 58 g
∴ 0.38 mole Co= (58 X 0.38) g
= 22.04 g
So, the required mass is 22.04 g
An endothermic process is a process that needs energy in order to proceed. This is the opposite of exothermic which is a process of releasing energy. During an endothermic process, the temperature of the system is increased thus exciting the molecules and allowing them to move faster. This will cause liquid to vaporize.
Answer:
degree of hotness or coldness measured on a definite scale. the degree of heat that is natural to the body of a living being. abnormally high body heat running a temperature.
Explanation:
It becomes ionized and attains its stable electronic configuration.
Answer:
The first two options are correct
Explanation:
The first two options are part of the benefits of a parallel connection of bulbs in a circuit. Here, the voltage of each connecting bulb is the same as the voltage of the bulb in the circuit hence all the bulbs have the same voltage running through them. Thus, when one bulb is removed/burns out, it does not affect the remaining bulbs (those ones will remain lit). Also, the addition of bulb(s) does not cause the remaining bulbs in the circuit to get dimmer (since they will all have the same voltage).
