Rachel's parents live on a farm. Her mother decided to try and make it a working farm. She raised 60 goats, then entered into a series of business transactions. She traded all the goats for sheep at an exchange rate of 5 goats for 7 sheep. Next, she exchanged all the sheep for hogs at a rate of 4 sheep for 2 hogs weighing 250 lbs. each. She sold all the hogs at a market price of $55.00 per 100.0 lbs. How much money did she make from the 60 goats?
Explain how do reaction rates typically depend on temperature. Explain what part of the rate law is temperature dependent
by what factor does the rate of the reaction with the followingrate law change if the concentrations of no2 andcl2 are
Consider another expandable balloon is filled with nitrogen gas. The density of the gas is 1.24 g/L and the outside pressure is 1.05 atm. What is the temperature of the gas?
Explain what is the mole fraction of methane in the mixture. Presume that the water produced by the combustion is in the gaseous state.
the MWP for a tank is 207.0 bar at 20 degrees C. If the tank is filled at 200.0 bar at 20 degrees C, what is the maximum pressure the tank achieves if left in the sun on a boat, if the tank temperature reaches 35.0 degrees C?
Gaseous oxygen is held in 2 separate containers at identical temperature and pressure. The volume of container A is 7.92 L and it contains 0.209 mol of the gas. The volume of container B is 2.45 L. How many moles of the gas are in container B
Determining the Lewis structures of small compounds is the first step towards determining the molecular shapes of larger and larger molecules. Determining the shapes of amino acids, proteins (enzymes), etc.
a 45.0 g aluminum block initally at 28.0 celsius absorbs 825 joules of heat. what is the final temperature of the
When compound Y is heated, it decomposes to the element X and hydrogen gas. Decomposition of 1g of Y yields 0.0250 mol of gas. Calculate the possible molar mass values for X.
A certain quantity of a gas occupies 61.3 mL at 68 ?C. If the pressure remains constant, what would be the volume of the gas at 128 ?C?
Presume the pressure on a 1 kg bar of iron was raised from 1 atm to 1000 atm at a constant temperature of 25 °C. Specified that the density of the bar is 7874 kg/m3, is 11.8 x 10-6 K-1, define what is the entropy change (in J/K) of the iron bar
