This represents three steps of the rock cycle. the sediments are layered and compressed in sedimentary rock. the sedimentary rock is heated and compressed to form metamorphic rock. one thing remains the same from start to finish: the total amount of minerals present. this process represents an important scientific law. what is it? a) law of motion b) law of thermodynamics c) law of conservation of mass d) law of conservation of energy

Describe the interaction that occurs between two objects with the same electrical charge.

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3 -> a2cr(no3)3 + a3ag2so4

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
