2. A test measuring basic math skills in adults is normally distributed, with mean = 20 and standard deviation = 7. Calculate the z score and T score for each of the following test scores: - X = 11
At constant volume, the heat combustion of a particular compound is -3447.0 KJ/mol. When 1.205 g of this compound (molar mass = 119.94 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 5.007 degrees C. What is the heat...
Consider the molecular level representation of a gas There are: (a picture) 6 blue dots 5 orange dots 3 green dots (i think they are the diatomic one, because it is pairs) If the partial pressure of the diatomic gas is .750, what is the total temperature? I am totally lost, be...
Z= x-u/o So, 296-300/3 = -.77 Look at a standard normal distribution table .2794 is the value from the table. If you draw the curve, you will know that the area is to the left. So, you subtract: .5000- .2794 =.2206 is the probability. I am not sure about the second part.
If the heat from burning 6.000 g of C6H6 2C6H6(l) + 15O2(g) -> 12CO2(g) + 6H2O(l) + 6542 kJ is added to 5691 g of water at 21 °C, what is the final temperature of the water? Please tell me what I am doing wrong: 293,551= 5691*4.2*(Tf-21C) 293551= 23902.2Tf - 50946.2 343...
