Four students are analyzing four different substances and recording their findings in this table.

a 3-column table with 4 rows titled properties of substances. the first column titled substance has entries leonna's substance, xiao's substance, blake's substance, amir's substance. the second column titled definite shape has entries x, nothing, x, nothing. the third column titled definite volume has entries x, x, nothing, nothing.

which most describes this table?

leonna has a solid, xiao and blake have liquids, and amir has a gas.
leonna and amir have gasses, xiao has a liquid, and blake has a solid.
leonna has a solid, xiao has a liquid, blake has a gas, and amir made a mistake.
leonna has a solid, xiao has a liquid, blake made a mistake, and amir has a gas.

Compare the valence electron configuration of the nobles gas elements seen here. what statement is correct?

The reactions of photosynthesis occur in the of plant cell? a. mitochondria. b. lysosomes. c. chloroplasts. d. chlorophyll

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
