1) Describe the movement of gas particles.
2) Compare the shape and volume of a solid and a gas.
3) Gases are easily compressed. What danger is associated with this property of gases.
a particle has a velocity equal to 0.25 c and a wavelength of 1.3 x 10^-16 m. Calculate the mass of the particle in kilograms. c=3.0 x 10^8 m/s
Which reagent is the limiting reactant when 1.250 g Al(OH)3 and .750 g H2SO4 are allowed to react? How many moles and grams of Al2(SO4)3
How many moles of NH3 can be produced from the reaction of 0.5 moles of N2 with that amount of H2?
Compute the enthalpy change, , for this reaction per mole of (Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 and 1.00 ] )
What is the equilibrium partial pressure of N2O4? (atm) (b) Calculate the value of Kp for the reaction. (c) Calculate the value of Kc for the reaction.
Gold miners then react the basic aqueous product solution from the above equation with Zn dust to get gold metal. Write a balanced redox reaction for this process.
If 17.0 mL of 0.800 M HCl solution are needed to neutralize 5.00 mL of a household ammonia solution, what is the molar concentration of the ammonia?
How is concentration an intensive property? I mean if you add more amount of a substance(mass), the number of moles increase and so the concentration increases.
A solid sample containing some Fe 2+ ion weighs 1.062g. It requires 24.12 mL 0.01562 M KMno4 to titrate the Fe2+ in the dissolved sample to a pink end point.
