Three glass bulbs, joined by closed stopcocks, have the following volumes and initial pressures of the specified gases. Bulb A: 100. mL of CO(g) at 190. torr

Bulb B: 200. mL of H2S(g) at 1.00 atm

Bulb C: 500. mL of Kr(g) at 75.994 kPa

After both stopcocks are opened and the gases allowed to diffuse throughout, what will be the final total pressure?

(The ambient temperature is constant.)

Ptotal = 0.750 atm

What is the partial pressure of H2S(g)?

PH2S =

What is the mole fraction of Kr(g)?

ΧKr =

This chart lists four kinds of polymers and their sources. what can be known about all four polymers, despite their differences? they come from living things. they share ionic carbon bonds. they are at least 100 monomers long. they are made of repeating subunits.

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
