If 25 kg of ice at 0c is combined with 4 kg of steam at 100c, what will be the final equilibrium temperature (in c) of the system? latent heat of fusion of ice = 3.34 x 105 j. kg-1 latent heat of steam = 2.23 x 106 j. kg-1 specific heat of water = 4180 j. kg-1.k-1

Can smoke be transformed into liquid or used as energy or both?

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )
