what happens when the calorimeter cup has several milliliters of water in it when you added in the HCl
When 1.0 g of snack cake is combusted in a constant-pressure bomb calorimeter with a heat capacity (including its water) of 10.0 kJ/°C, the temperature of the calorimeter rises by 2.24°C. How many nutritional calories (Calories) are in one serving..
You have 170. mL chlorine trifluoride gas at 669 mmHg and 45°C. What is the mass (in g) of the sample?
Car manufacturers are developing engines that use H2 as fuel. In locations where hydroelectric plants produce inexpensive electric power, the H2 can be made industrially by the electrolysis of water.
What is the final temperature of a mixture of that 5.00 x 102 mL of hot water at 95.0°C and 475 g of -12.0°C ice cubes? (NOTE that in this process, the ice heats up to its melting point, melts, and then heats to the final temperature of the mixtur..

The temperature at which a substance melts or boils depends upon the strengths of the intermolecular forces. What must happen for a substance to melt in terms of particles, intermolecular forces, and energy
A solution contains 4.64g KCl in 178 mL of solution. The density of the KCl solution is 1.14 g/mL. What is the molarity,M, for the potassium chloride solution?
Rank from longest to shortest distance. To rank the items as equivalent, overlap them.
First, plot the potential energy as a function of the electron's distance from the nucleus, i.e.,V(r) . (Be sure to remember the sign of this potential.)
