Suppose you mix two volumes of water: 25.0 mL at 15°C and 35.0 mL at 68°C. What's the final temperature of the water? Assume the density of the water is 1.0 g/mL at both temperatures and the heat capacity of water is 4.184J/g°C.

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold

What is a main difference between a mixture and a pure substance? a mixture is only a liquid, but a pure substance can be in any state. a mixture looks the same throughout, but a pure substance does not.1 a mixture can vary in composition, but a pure substance has a set composlo a mixture can be made up of a single compound, but a pure substance car

The sum of the oxidation numbers in a neutral compound is always
