Why the heat is lost to the surroundings
What is the final temperature when 121 mL water at the 30.°C is mixed with 63 mL water at the 84°C? Assume that no heat is lost to the surroundings and that the density of water is 1.00 g/mL.

Determine the numbers of grams of water must be added to 200 mL of NaOH solution in order to have a solution with a specific gravity of 1.157, 13.55% when the specific gravity of NaOH = 1.32, 28.83%
Determine the molecular weight of an unknown gas if 200 mL of this gas diffuses through an apparatus in 180 seconds while the 250 mL of NO2 under the same conditions diffuses through the same apparatus in 170 seconds?
Assuming no heat is lost to the surroundings, what is the temperature of the water and the metal? 40grams of a certain metal at 98 degrees Celsius was placed into the 80mL of water at 297K. Where the specific heat of the metal = 0.085 cal
Explain how long would it take in seconds to increase the temperature of the water from 12.0oC to41.5oC when a bowl of 345 g of water is placed in a microwave oven that puts out the 766 watts (J/s).
Explain why is it important to fill the burette with the NaOH solution before performing a acid/base titration, and discuss what effect does that have on the determination of the Ka of the acid?
Calculate the approximate sample mean, sample variance, sample standard deviation, sample median, and sample mode from the data in the following frequency distribution:
The combustion analysis of toluene, a common organic solvent, forms the 0.00137g of H2O and 0.00586g of CO2. If the compound contains only hydrogen and carbon, determine the molecular formula when the molecular mass is 92g/mol.
Hydrogen gas,H2(g) and the Carbon dioxide gas, CO2 (g), are brought together in a vessel and heated to1565oC. At this temperature they react to produce the water, H2O(g) and the carbon monoxide oxide, CO(g). Explain, are the reactants or the
