Which of the following is true of the the law of conservation of energy? Energy is not created nor destroyed except with the addition of oxygen Energy is not created or destroyed under ordinary conditions, but it may be changed from one form to another Matter may be changed from one form to another under ordinary conditions but cannot be created or destroyed, except in nuclear reactions Matter can only be created with the addition of oxygen None of the answer choices are correct.

Need what is special about water as a compound? how does water regulate climate? what drives water evaporation?   why is the water vapor fresh water when it rises from the ocean? why might freshwater in the form of snow take longer to enter the water cycle again than liquid precipitation?   what is an aquifer? what role do people play in the water cycle? plz just answer as many as you can ! thx if you !

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution

Concentrations expressed as a percent by mass are useful when the solute is a a. liquid b. gas c. solid
