A portion of the periodic table is shown below: A portion of the seventeenth and eighteenth columns of the periodic table is shown. Column 17 reads nine fluorine 18.998 and 17 chlorine 35.453. Column 18 reads 10 neon 20.180 and 18 argon 39.948. Which element has the electron configuration 1s22s22p6? Argon (Ar) Chlorine (Cl) Fluorine (F) Neon (Ne)

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
