If you add a solvent called "dioxane" to water, a homogenous mixture forms. Dioxane and water have the same boiling point (100oC). How do you explain that the mixture of the two compounds shows a boiling point that is lower than the one found for either of the pure liquids
How is the ideal gas law modified to account for the finite volume of molecules? The temperature of the sea bed 60 m below the surface and at the surface are both 20C. A rubber balloon is inflated at the sea bed with 2.0 mole gas neglecting the wo..
In the unbalanced reaction, Sn + HNO3 ---> Sn(NO3)2 + H2), 2.100 grams of Sn(NO3)2 was formed. How many grams of NO were formed and how many moles of HNO3 were reacted? (HINT: the coefficient of Sn is 3).
The following processes is a likely change in a redox reaction. Label the chemical change as an oxidation process, a reduction process, or neither
What is the mass percent, expressed to the proper number of significant figures, for each metal in the original metal mixture? Define all variables, show units, and show algebraic steps to your the answers.
A chemist wants to prepare 0.65 M HCl. Commercial hydrochloric acid is 12.4 M. How many milliliters of the commercial acid does the chemist require to make up 1.48 L of the dilute acid?
