A student added 0.40 mL of acetic anhydride instead of 4.0 mL. Did this procedural error affect the theoretical yield of her preparation? Briefly explain.
Using a sample of water with a mass of 46.0 grams at a temperature of -58. Degree Celsius calculates how many Joules of energy (E) are necessary to heat the ice to 0 degree Celsius. Specific heat of ice= 2.1 J/g C).
One molecular form of elemental sulfur is a ring of eight sulfur is a ring of eight sulfur atoms. As one molecule of this element is burned to make sulfur trioxide, how many oxygen molecules are used?
Consider the reaction that will take place between (S) -2-bromobutane and sodium azide in DMF. A) What is the product of this reaction (give proper stereochemistry of the product formed)
The Haber process is very important for agriculture because it converts N2 (g) from the atmosphere into bound nitrogen which can be taken up and used by plants. The reaction is N2 + H2->NH3
Consider a hypothetical reaction in which A and B are reactants and C and D are products. if 15grams of A completely reacts with 12grams of B to produce 14grams of C, how many grams of D will be produced.
