You are running a rather large scale reaction where you prepare the grignard reagent phenylmagnesium bromide by reacting 210.14 grams of magnesium with 772 ml of bromobenzene. how many moles of grignard reagent would you expect to form? (the density of bromobenzene is 1.495 g/ml, mg = 24.3 g/mol, bromobenzene=157.01 g/mol)
for example, nacl reacts with agno₃ to produce nano₃ and agcl (a precipitate). the chemical equation for this reaction will be:
nacl + agno₃ → nano₃ + agcl (s)
the complete ionic equation for the same reaction will be:
na⁺ + cl⁻ + ag⁺ + no₃⁻ → na⁺ + no₃⁻ + agcl (s)
excepting for the agcl solid, all other species in the ionic equation are written as ions.nacl exists as na⁺ ions and cl⁻ ions.agno₃ exists as ag⁺ ions and no₃⁻ ions.nano₃ exists as na⁺ ions and no₃⁻ ions.agcl does not dissolve in water. rather, its ions stay intact within the ionic lattice.
their subscripts show their charges. there's no subscript in the chemical equation. it takes some reasoning to tell the ions formed from each of the species.
the newton is the si unit for force; it is equal to the amount of net force required to accelerate a mass of one kilogram at a rate of one meter per second squared. newton's second law of motion states: f = ma, multiplying m (kg) by a (m/s 2 ).
i don't understand your question, but i think that would .
in a sugar crystal, the sucrose molecules are arranged in a repeating pattern that extends in all three dimensions, and all of these molecules are attracted to each other by inter-molecular forces that is a type of interaction that binds molecules together and is weaker than the bonds between atoms in a molecule.
the bond between the oxygen and hydrogen atoms (o–h bond) in sugar (sucrose) gives the oxygen a slight negative charge and the hydrogen a slight positive charge.the polar water molecules attract the negative and positive areas on the polar sucrose molecules which makes sucrose dissolve in water.
