I think that it doesn’t break the law of multi. Pro. But does break the law of def. pro. But I’m not sure

Calculate the amount of heat needed to boil 162 g of ethanol (CH3CH2OH), beginning from a temperature of -60.8 degrees celsius . Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol.

1)A farmer is using a bushel basket to pour apples into a rectangular bin that has a base that is 5.000 meters by 4.000 meters. If the farmer pours 356 baskets full of apples into the bin, how high will the apples fill the bin in meters? Assume each basket is exactly one bushel and that the apples uniformly fill the bin. Show all of your work. Assume 1.000 bushel=35.24 liters.

Use your graph to answer the following. Enter your answers here in complete well-constructed sentences. What is the equation of your best-fit line? y=-12031x +34.91 1. What are the units of the X axis? the units of the X axis are 1/T (In Kelvin) 2. What are the units of the Y axis? The units of the Y axis are In(Ksp) (In is unitless) 3. What are the units of the slope? The units of the slope are K^-1/In(Ksp) What is the expected value for In(Ksp) at 25°C? Briefly explain how you determined this value. The expected value is In(Ksp)= -5.43541 at 25 degrees C First I changed the 25 degrees C into K so it will be able to fit into the 1/K portion of the equation. Then using the slope values from the graph I used those numbers for the equation. What is the expected value for Ksp at 25°C? The expected value is Ksp= 0.004339 What is the value of AH° in kJ/mol? What is the value of AS in J/(mol K)?

Which of the following units is a Sl unit? O 1 watt O joule/sec ampere O Newton

Q4: Describe physical and chemical properties and physical/chemical processes with a special focus on the change of state of matter and how this change relates to energy.

Express your answer in joules per kelvin to one decimal place. C2H2(g)+H2(g)→C2H4(g)C2H2(g)+H2(g)→C2H4(g)   C(s,diamond)+H2O(g)→CO(g)+H2(g)C(s,diamond)+H2O(g)→CO(g)+H2(g)   CO(g)+H2O(g)→H2(g)+CO2(g)CO(g)+H2O(g)→H2(g)+CO2(g)    4NH3(g)+5O2(g)→4NO(g)+6H2O(l)

Which is not a physical property of chlorine? The color of gaseous chorine is green. Chlorine freezes at -101°C. O Chlorine and sodium combine to form table salt. The density of chlorine gas at STP is 3.17 g/L.
