If an atom of nitrogen binds with three hydrogen atoms to form a molecule of ammonia, how many lone pairs of electrons does nitr
2 answers:
Answer:The correct answer is option A.
Explanation:
Nitrogen binds with 3 hydrogen atom to give ammonia .
Electronic configuration of Nitrogen is given as:
Nitrogen has 5 valence electrons and needs three electrons to complete its octet.
In ammonia molecule nitrogen atom accepts three electrons from each hydrogen atom.
Electron as lone pair = Valence electrons - Number of electrons in bonding
= 5 - 3 = 2 = 1 pair electrons as present as lone pair

Answer:
87.15%
Explanation:
To find percent yield, we can use this simple equation
Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.
They give us these values, so to find the percent yield, just plug the numbers in.
So, the percent yield is 87.15%
An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.
