I like that game Forza horizon
The reaction of N2 and H2 to generate NH3 is as follows:N2 + 3H2 ⇒2NH3
Since H2 is in excess amount in this reaction, the determine factor is N2. The ratio of N2 and product NH3 is 1:2. Therefore, 4.08 moles of N2 can generate 4.08*2 = 8.16 mole of NH3.
Grams of NH3 = moles of NH3 * molar mass of NH3 = 8.16 mole * 17 g/mole = 139 g.
139 grams of nh3 can be produced from 4.08 mol of n2 and excess h2.
Answer:
From the diagram, the water is being boiled. This process vaporises the water in the vessel leaving salt crystals behind.
Since the water is needed in liquid form, the cold water at the top of the set-up
condenses the vapor so it can be used.
Answer: 27 is A and 28 is C.
Explanation: I’ll explain 28 but not 27 because that’s just definitions.
In CuSO4 there is a Cu, an S, and 4 O molecules. Add them up you get 6.
Answer:
When you heat ice, its temperature rises, but as soon as the ice starts to melt, the temperature stays constant until all the ice has melted. This happens because all the heat energy goes into breaking the bonds of the ice's crystal lattice structure.
