A cylinder with a piston holds 3.50 moles of a diatomic gas. The gas in the cylinder absorbs 875 J of energy due to the higher temperature of the environment. At the same time, the cylinder expands to a larger volume, doing 112 J of work on the environment. (a) What is the change in internal energy of the gas in the cylinder (in J)

Indicate whether the specified alkyl halides will form primarily substitution products, only elimination products, both substitution and elimination products, or no products when they react with sodium methoxide. 1-bromobutane 1-bromo-2-methylpropane 2-bromobutane 2-bromo-2-methylpropane

How does the presence of oxygen affect the chemical pathways used to extract energy from glucose?

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
