The amount of kinetic energy in a system is a constant value. B. An object can have potential energy or kinetic energy, but not both at the same time. C. Energy can be converted from one form into another, but it cannot be created or destroyed. D. The amount of energy created when an object moves is equal to the energy destroyed when it stops moving

Titration reveals that 11.6 ml of 3.0m sulfuric acid are required to neutralize the sodium hydroxide in 25.00ml of naoh solution. what is the molarity of the naoh solution?

A0.10 m aqueous solution of sodium sulfate is a better conductor of electricity than a 0.10 m aqueous solution of sodium chloride. which of the following best explains this observation? (a) sodium sulfate is more soluble in water than sodium chloride. (b) sodium sulfate has a higher molar mass than sodium chloride. (c) to prepare a given volume of 0.10 m solution, the mass of sodium sulfate needed is more than twice the mass of sodium chloride needed. (d) more moles of ions are present in a given volume of 0.10 m sodium sulfate than in the same volume of 0.10 m sodium chloride. (e) the degree of dissociation of sodium sulfate in solution is significantly greater than that of sodium chloride.
