The thermochemical equation for the combustion of hexane is shown below.                  C6H14(g)  +  19/2 O2(g)  →  6 CO2(g)  +  7 H2O(g)                ΔH° = -4163 kJ What is the enthalpy change for the combustion of 2.50 g C6H14?  Molar mass of C6H14 = 86.18 g/mol

Which is the priority outcome for the patient with pulmonary embolism and the nursing diagnosis impaired gas exchange related to impaired pulmonary perfusion?

Samples of six bolts are taken periodically and their diameter (in mm) are measured.   Thirty consecutive sample are taken and each sample mean and range in calculated.  The overall means are Xbarbar=9.81 and Rbar=1.14.  What is the upper 1

Based on the following thermochemical equations, what is the heat of vaporization of titanium(IV) chloride?   Ti(s) + 2 Cl2(g) → TiCl4(l)             ΔH = –804.2 kJ/mol TiCl4(g) → 2 Cl2(g) + Ti(s)            ΔH = 763.2 kJ/mol

Examine the graph of the function below.  Use this graph to sketch the graph of the inverse function,

A 35.6 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter, according to the following reaction.  If the temperature rose from 35.0 to 76.0°C and the heat capacity of the calorimeter is 23.3 kJ/°C, what is the value of DEcombper mol of ethanol?  The molar mass of ethanol is 46.07 g/mol.   C2H5OH (l) + 3O2 -> 2CO2(g) + 3H2O(g)

This question has two parts.(a) On your own paper sketch the graph of the rational function and state largest domain on which the function is one-to-one.  Be sure to explicitly label at least three points on the graph. [For your typed answer to part (a), give the ordered pairs of the points you labeled, and state any asymptotes as equations](b) Find the inverse function

What is the formula that describes the relationship between the volume and number of moles in the sample at constant pressure and constant temperature? (Where k is a constant)
