Consider the chemical equation below.

mg(oh)2 + 2hno3 --> mg(no3)2 + 2h2o

which is the net ionic equation? (b. is already incorrect.)

a. h^+ + oh^- --> h2o
c. mg^+2 + 2no3^- --> mg^+2 + 2h2o
d. mg^+2 + 2oh^- + 2h^+ + 2no3^- --> mg^+2 + 2no3^- + 2h2o

Balance this equation: n2 + h2 > nh3, write the following molar ratios: n2 / n2 / nh3 h2 /

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

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.
