4. Se recoge gas hidrogeno sobre agua a 25°C. El volumen del gas recogido es de 35 ml y la presión es de 758 mmHg. Si el gas estuviera seco y medido en condiciones
normales ¿Cuál sería el volumen? (P-(H2O) a 25 °C = 23.8 mmHg).

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?

Using the first volume and temperature reading on the table as v1 and t1, solve for the unknown values in the table below. remember to use the rules of significant figures when entering your numeric response.

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
