Draw the product that is formed when 1-pentyne is treated with an excess of hydrogen gas and a nickel catalyst.
CH triple bonded to CH CH2CH2CH3
At 1500 degrees C the equilibrium constant for the reaction CO(g)+2H2(g) -->
Calculate the pressure and the temperature of the compressed gas. In a diesel engine the compression ratios are typically much higher; redo the same calculation for the compression ratio of 20:1.
Write the chemical equation for the overall reaction. (Part B) Identify any molecule that acts as a catalyst in this reaction. (Part C) Identify any molecule that acts as an intermediate in this reaction.
Why is molarity not the best means of stating acid strength? Is molarity the most representative form of quantifying acids and bases?
You have a gas occupying 75L at 800 torr and 315K. What is the volume if the pressure is decreased to 600 torr and the temp is changed to 127 C?
Suppose a volume is divided into three equal parts. How many microstates exist for distributing four molecules among the three parts?
an aerosol spray can with a volume of 270 ml contains 3.2 g of propane gas propellant. what is the pressure in the can at 20 c.
The excess EDTA was then back-titrated, requiring 5.00 mL of 0.050 0 M Zn2. What was the concentration of Ni2 in the original solution?
Calculate the concentration of magnesium and calcium in ppm. Record your answers as ppm Mg2+, and Ca2+ espectively. For each answer indicate the ppm as CaCO3 also.
Calculate the amount of energy needed in calories to heat 145 g of water from 22.3 degrees celsius to 75.0 degrees celsius. (water in j/g degree celsius = 4.184, cal/ g degree celsius = 1)
derive an euation relating the temperature to the velocity of the gas.if nitrogen at 150 degree celcius flows past one section of the tube at a velocity of 2.5 metre/second,what is its temperature at another section where its velocity is 50 m/s
