De acuerdo con la siguiente ecuación ¿Cuántos gramos de H3PO4 reaccionan con 5.70 mol de Ca(OH)2? b) ¿Cuántas mol de agua se producen si se obtienen 500 g de Ca3(PO4)2? c) ¿Cuántos gramos de H3PO4 son necesarios para producir 275 g de agua?

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.
