Four beakers of equal size with equal volumes contain four different solutions of salt water as seen above. If beaker 1 has 55 g of salt dissolved in 500 mL, beaker 2 has a concentration of 0.21 g/mL, beaker 3 has 36 g of salt dissolved in 144 mL of water, and beaker 4 has a concentration of 0.23 g/mL, then which of the following lists the solutions in order from most concentrated to least concentrated? A)2, 4, 3, 1

B)3, 4, 2, 1

C)1, 2 4, 3

D)1, 2, 3, 4

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
