If 18.75 mol of helium gas is at 10.0 degree C and a gauge pressure of 0.350 atm, a. Calculate the volume of the helium gas under these conditions. b. Calculate the temperature if the gas is compressed to precisely half the volume at a gauge pressure of 1.00 atm.

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?

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

+= + + balance the equation on coefficients, ex. 1,1,1
