The standard enthalpy of certain reaction is approximately constant at + 125kJmol-1 from 800K to 1500K. The standard Gibbs energy is + 25kJmol-1 at 1150K. Estimate the temperature at witch the equilibrium constant becomes greater than 1.

Enter a balanced equation for the combustion of gaseous ethane (c2h6), a minority component of natural gas, in which it combines with gaseous oxygen to form gaseous carbon dioxide and gaseous water.

The structure of benzene can best be described as a

What is the molarity of a solution made with 298g of potassium chloride dissolved in enough water to make 2L of solution?

Why is mass conserved in a chemical change? The energy used in the chemical reaction burns up the extra matter. The compounds are still exactly the same, they just look different.

Where the use of energy is concerned (in scientific sense), when is work done?

Properties of a solution that depend only on the ratio of the number of particles of solute and solvent in the solution are known as: intensive properties extensive properties colligative properties chemical properties
