Answer:
CH4
Explanation:
In solving this problem, we must remember that one mole of a compound contains Avogadro's number of elementary entities. These elementary entities include atoms, molecules, ions etc. Recall that one mole of a substance is the amount of substance that contains the same number of elementary entities as 12g of carbon-12. The Avogadro's number is 6.02 × 10^23.
Hence we can now say;
If 163 g of the compound contains 6.13 ×10^24 molecules
x g will contain 6.02 × 10^23 molecules
x= 163 × 6.02 × 10^23 / 6.13 × 10^24
x= 981.26 × 10^23/ 6.13 ×10^24
x= 160.1 × 10^-1 g
x= 16.01 g
x= 16 g(approximately)
16 g is the molecular mass of methane hence x must be methane (CH4)

Which has potential energy
Explanation:
<span>Having too much water in the body could cause so much complications; just as having too little can be dangerous. In each of these scenarios the body tries to maintain equilibrium through a process called homeostasis. Homeostasis depends on many variables, such as body temperature and body fluid being kept within certain pre-set limits. The essence of homeostasis is maintain bodily functions and metabolism at equilibrium state. If Loiue takes in so much water in a very hot atmosphere or during summer even though he's not thirsty, his body would have to get rid of the excess water by sweating. On the other, during winter, or in a cold environment Loiue's body would have to get rid of excess water by urinating frequently.</span>
The answer is Na⁺.
Na⁺ is a positive ion of sodium that is due by the loss of one electron.
4He represents four atoms of helium. It is an idel gas, that do not form elementary molecules and exist in atom form.
Ca represent one atom of calcium and Mg one atom of magnesium. They are metals and do not form elementary molecules.
