How can you make an item that is made of magnetic material become a permanent magnet instead of a temporary magnet? *.

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

In a chemical reaction, the final amount of the products is determined by the a. universal gas law b. law of definite proportions c. air pressure d. temperature e. none of the above me

Charles's law describes the relationship of the volume and temperature of gas at a constant mass and pressure. according to this law, what would happen to the temperature of the gas if its volume decreased from 1.0 l to 0.50 l?
