Because chlorine has the highest electronegativity among the four, it has the greatest tendency to attract electrons in a chemical bond.

Therefore, (2) chlorine is the best answer.

Hope this helps~

Answer: (2) chlorine

Expalanation: 1) Carbon is an element with atomic number 6 and thus has 6 electrons. It's electronic configuration is:

C:1s^22s^22p^2

Carbon needs to lose or gain 4 electrons to attain noble gas configuration.

2) Chlorine is an element with atomic number 17 and thus has 17 electrons. It's electronic configuration is:

Cl:1s^22s^22p^63s^23p^5

Chlorine needs to gain 1 electron to attain noble gas configuration and thus has strongest tendency to attract electrons in a chemical bond.

3) Silicon is an element with atomic number 14 and thus has 14 electrons. It's electronic configuration is:

Si:1s^22s^22p^63s^23p^2

Silicon needs to lose or gain 4 electrons to attain noble gas configuration.

4) Sulfur is an element with atomic number 16 and thus has 16 electrons. It's electronic configuration is:

S:1s^22s^22p^63s^23p^4

Sulfur needs to gain 2 electrons to attain noble gas configuration.

Answer:

option C = Reactant: 4NH₃ + 6NO   →   product:  5N₂  + 6H₂O

Explanation:

Chemical equation:

NH₃ + NO   →  N₂  + H₂O

Balanced chemical equation:

4NH₃ + 6NO   →  5N₂  + 6H₂O

Ammonia is react with nitrogen mono oxide and produced nitrogen and water.

Ammonia and nitrogen monoxide are reactants while water and nitrogen are product.

Why is the vapor pressure of a warm pale higher than the vapor pressure of a cold lake
levacccp [35]

The vapor pressure of a warm pale higher than the vapor pressure of a cold lake because Warm water evaporates more quickly.

Hence, Option B is correct answer.

<h3>What is Evaporation ? </h3>

The process in which a liquid or solid is converted into vapour is called Evaporation. When water gains the heat energy then it changes in to gas. When the temperature increases it speeds up the rate of evaporation.

The temperature of warm water increases, the kinetic energy of the warm water molecule also increases.

Thus from the above conclusion we can say that The vapour pressure of a warm lake is higher than the vapor pressure of a cold lake because Warm water evaporates more quickly.

Hence, Option B is correct answer.
