When 47.3 J of heat are added to 13.4 g of a liquid, its temperature rises by 1.74 °C.When 47.3 J of heat are added to 13.4 g of a liquid, its temperature rises by 1.74 °C. THIS IS THE ANSWER, BUT HOW TO GET THAT?
J/(g⋅°C)
A 14.7-g ice cube is placed into 324 g of water. Calculate the temperature change in the water upon complete melting of the ice. Determine how much heat is absorbed by the melting ice and then use q = mC?T to calculate the temperature change of the..

At 298K, 125 ml of 0.60 M potassium hydroxide KOH is added to 175 ml of 0.40 M hydrochloric acid HCl. What is the final pH
Lead (2) nitrate reacts with potassium iodide to produce lead (2) iodide and potassium nitrate. if 1.23mg of lead nitrate are consumed, what is the mass of the potassium nitrate produced?
State the equilibrium constant expression in terms of reactant as well as product concentrations for the following reactions
Assume your eyes receive a signal consisting of blue light, the wavelength= 470nm. The energy of the signal is 2.50x10^-14 J. How many photons reach your eyes
If 55.0 mL of ethanol ) initially at 8.0C is mixed with 55.0 ml of water (density = 1.0g/mL) initially at 28.6C in an insulated beaker, and assuming that no heat is lost, what is the final temperature of the mixture
The equilibrium constants needed to work this problem are given in Table 2-3 (under Phosphoric Acid). Hint: use the mass balance equation for phosphate species and equilibria expressions to solve this problem
A radiometric dating technique uses the decay of U-238 to Pb-206 (the half-life for this process is 4.5 billion years) to determine the age of the oldest rocks on Earth and by implication the age of Earth itself.
Molecular distances are usually given in nanometers (1 nm = 1 × 10-9 m) or in picometers (1 pm = 1 × 10-12 m). However, the angstrom (Å) unit is sometimes used, where 1 Å = 1 × 10-10 m. (The angstrom unit is not an SI unit.) If the distance betwee..
