Probability
How do I determine the probability of selecting a card greater than 9 or a black card?

probability
The odds against Paul Phillips winning the 100 yard dash are 7:2. Determine the probability that: • a) Paul wins. • b) Paul does not win. How do I set this up to find out the equation/answer?

chemistry
4. Use the pressure of the butane gas (your answer from question #3 above), along with the temperature and volume recorded in the lab, to determine the moles of butane gas collected in the lab. You will use the ideal gas law (and the ideal gas constant, R) for this calculation...

Math
Would the set up be [(p-->q)^~p]-->~q

Math
If you pass general chemistry, then you can take organic chemistry. You pass general chemistry. ˆ You can take organic chemistry. Let P = you pass general chemistry Let Q = you can take organic chemistry I came up with P - >Q P therefore Q But my set up is wrong,...

precalc
f(x)=Log1/3^(9x)find the domain and range.

chemistry
consider the following reaction: 2C2H6(g)+7O2 (g)-->4CO2(g)+6H2O (g) delta H = -3120kJ If 3.00g of ethane are burned, how many kJ of heat are produced?

chemistry
consider the following reaction: C3H8 (g)+ 5O2 (g)--> 3CO2 (g)+ 4H20 (g) Delta H = -2440kJ The heat of formation of CO2 is -390 kJ/mol and the heat of formation of H2O is -240 kJ/mol. What is the heat of formation of propane?

chemistry
the following reaction is carried out in a bomb calorimeter: 4NH3 (g) +5O2 (g)-->4NO (g)+6H2O (g) The calorimeter constant is 45.0kJ/K. when 34.0g of NH3 are reacted in the calorimeter, the temp rises by 10 degrees C. What is the change in energy, delta E, for the rxn?"

Spanish
when you are talking in past tense. for example: you went swimming yesterday.
