The reaction of NO * (g) with g) is represented by the balanced equation below. A chernist carried out the reaction at 573K , starting with 0.100mol of each reactant in a 1.00L container with variable volume . The reaction mixture quickly reached equilibrium , as indicated in the graph below . The chemist reduces the volume of the equilibrium system by half while keeping the temperature constant . Which of the following predictions about the yield of the reaction is best, and why?

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
