BALANCE the following equations then write the NET IONIC EQUATION for each one: Ni(NO 3 ) 2(aq) + NaOH (aq) → Ni(OH) 2(s) + NaNO 3(aq)

You have a sample of a gas that occupies a volume of 17ml at -111 degrees celsius. what volume does the sample occupy at 88 degrees celsius? show all work asap

How many moles of air are there in a human lung with a volume of 2.4 l at stp? explain your answer

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)
