A chemist adds 420.0 mL of a 1.2M silver nitrate (AgNO,) solution to a reaction flask. Calculate the mass in grams of silver nitrate the chemist has added to the flask. Round your answer to 2 significant digits.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

c) should be the answer.

c. orbital shape i hope this is correct
