What would i write in the results, conclusion, and keywords and research components for my 4th grade son's science fair project? we did the project on the growth of epsom salt crystals in 6 different glass jars, all done the same day but 2 in the am, 2 in the afternoon, and last 2 in the evening. they all grew crystals but the ones with the best growth were done at different times one was in the am and other was in afternoon. i'm stumped been done school a long time and very busy single mom of three.

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?
