In the important industrial process for producing ammonia (the haber process), the overall reaction is: n2(g) + 3h2(g) → 2nh3(g) + 100.4 kj a yield of nh3 of approximately 98% can be obtained at 200°c and 1,000 atmospheres of pressure. what is the δh in kj of heat released per mole of nh3(g) formed? a) 50.2 kj b) -50.2 kj c) 100.4 kj d) -100.4 kj

How many atoms of mg are present in 97.22 grams of mg? 6.022 × 1023 2.408 × 1024 4.818 × 1024 5.855 × 1025

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
