À cylinder measuring 3.9 cm wide and 4.7 cm high is filled with gas and the piston pushed down with a steady force. piston cylinder gas Calculate the force on the piston if the pressure in the gas is measured to be 639. kPa. Write your answer in units of kilonewtons. Round your answer to 2 significant digits.

Consider the following balanced equation. 2 Sb (s)  +   3 H2O (g)    →   Sb2O3 (s)   +   3 H2 (g) 5.0 L of H2O gas, with a pressure of 1.29 atm and a temperature of 96.7 °C reacted. How many mol of Sb2O3 were formed? Write out the problem on paper showing all conversion factors, unit cancellations, calculations, s.f., etc. Answer the questions related to the setup and calculation for this problem. Be sure to use our periodic table to calculate any molar masses needed (rounded to proper number of decimal places), otherwise your values might be slightly off and answers may be marked as incorrect. Abbreviate units as follows: grams = g, moles = mol, liters = L, atmospheres = atm   What temperature (with proper s.f.) is entered into the equation? Enter the value in the first blank and the units in the second blank.     Calculate the mol of H2O reacted (enter value only, with proper s.f.).  mol   Use the three blanks to enter the number, unit, and substance (in this order) that appears in…

Find the density of Freon-11 (CFC13) at 110.0 °C and 6.87 atm. Be sure your answer has the correct number of significant figures. Note: Reference the Fundamental constants table for additional information. g L 0x1.8 X

One of the steps to sweeten sour gas using the Claus process is reacting hydrogen sulfide gas with sulfur dioxide gas to produce water vapour and sulfur. 8.43 kL of hydrogen sulfide at 175 kPa and 250 °C reacts with excess sulfur dioxide. Calculate the mass, in kg, of sulfur produced.Do not show your work in the space provided.Record only your final answer with the correct number of significant digits and the proper units.
