Dalton's Law can be used to calculate the pressure of an individual gas present in a mixture of gases. The total pressure inside a 3 L flask containing oxygen gas (O2) and hydrogen gas (H2) at 35 °C is 105.50 kPa. (R-8.314 J K -Imol-1 ) (i) Calculate the pressure exerted by oxygen gas if the mass of oxygen gas inside the flask is 3.00 g. (M(O2) = 32 g mol-1 ) ?​

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

You open a can of soda at room temperature and hear a hiss. which of the following factors has changed inside the container? a.) atmospheric pressure b.) temperature of gas c.) type of gas d.) amount of gas

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
