Answer:
Iodine (I)
Explanation:
The atomic mass of Arsenic (As) is 74.92 amu. Also, we know that Halogen Group consists of following elements.
Fluorine, Chlorine, Bromine, Iodine, Astatine and Tennessine
And in given four options only Chlorine and Iodine belongs to halogen family. And we know that the atomic mass of chlorine is 35.45 amu which is less than that of Arsenic, therefore Iodine with atomic mass of 126.90 amu is the correct answer.
Answer:
Hii hello how are you....
Minerals need to be solid with a crystalline structure. Ice has these properties, liquid water does not. (i hope that helps you)
The correct answer is A. The image shows a nuclear fission. This takes place in any of the heavy nuclei after capture of a neutron. This is the opposite of nuclear fusion. In this case, nuclei are broken down into two.
Transfer and gain of kinetic energy by the water molecules takes place as water cycles from the bottom of the pot toward the top.
<h3>What is thermal energy?</h3>
Thermal energy is a another word to express the heat energy.
When we boil a water over a gas burner then due to convention, heat energy can be transfer to the bottom water molecules in the form of thermal energy. After gaining the thermal energy movement of water molecules increases as a result of the increase of the kinetic energy.
Hence, option (1), (2) & (4) are correct i.e. transfer and gain of kinetic energy by the water molecules is done.
