    Help determining state of products

    Hey all- I'm working on some problems about writing out and balancing chemical equations. I think I understand it pretty well except for determining the physical state of the products. Here's the specific problem I'm stuck on: solutions of barium chloride and potassium carbonate react to form a...

    How do reactant proportions affect the products of a chemical reaction?

    Is it correct that if you alter the proportions of the reactants of many chemical reactions, especially step-wise, the products will change? Here is an example, please tell me if it is right or not: KOH + H2SO4 ==> KHSO4 + H2O 2KOH + H2SO4 ==> K2SO4 + 2H2O

    What are the environmental implications of mineral oil in our products?

    I think hydrocarbons only affect air pollution when they are burned (though feel free to tell me if i am completely and utterly wrong) I also know that mineral oil goes through a distillation process to remove the toxins . . . and those filtered toxins must go somewhere. . . .that can't be...

    Determining amounts of reactants and products

    How many grams of oxygen are required to burn 8.8 g of C3H8 in the following equation: C3H8 + 5O2 --> 3CO2+ 4H2O The choices I have are a. 8 b. 12 c. 16 d. 32 e. 64 I think the answer is 32 but I'm unsure of how to get it. This is what I have so far. 8.8g C3H8 / 44g of C3H8 = .2mol of C3H8...

    Organic Reaction Product(s)?

    On an exam we were asked to "show the products of the substitution reaction and indicate the major product formed." The reaction is drawn. What would you put?
