. A reaction occurs between solutions of strontium bromide and silver nitrate, as shown in the equation below: SrBr2 (aq) + AgNO3 (aq) → Sr(NO3)2 (aq) + AgBr (s)
a. If 3.491 grams of the precipitate is formed, how many moles of strontium bromide were reacted?

Which statements are true about electrolysis? check all that apply. electrolysis requires an acid be present. electrolysis is described by two half-reactions. electrolysis is not an industrial process. electrolysis results in commercially valuable products. electrolysis involves the transfer of electrons. reduction results in the loss of electrons. oxidation results in the loss of electrons.

Reaction rate depends on how many molecules are coming into contact with each other with enough energy to react. increasing the temperature of the reactants will increase -

Which of these would be caused by a chemical change? a) the formation of lava. b) sedimantary rock layering over time. c) metamorphic rock forming from igneous. d) metamorphic rock eroding to form sedimentary rock.
