A solution of 2.50g of a compound having the empirical formula C6H5P in 25.0g of benzene is observed to freeze at 4.3°C. Calculate the molar mass of the solute and its molecular formula. Thank you! :)

Liv sheldon given the balanced equation for an organic reaction: c2h2 + 2cl2 → c2h2cl4 this reaction is best classified as *

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next

How might this scientific phenomena be explained? a paper clip floats on water.
