A10.0g sample of h2o(l) at 23.0degrees c absorbs 209 joules of heat. what is the final temp of the h2o(l) sample? explain.

Final temperature = 28.0 degrees C.

Explanation:

heat absorbed = mass * specific heat * rise in temperature.

The specific heat of water is 4.186 J /g/C so we have the equation

209 =  10 * 4.186 * x   where x is the temperature increase

41.86x = 209

= 5 degrees C.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
