Question 1) Write balanced ionic equations (if appropriate) for the following reactions
State one observation you could expect as the reaction proceeds for each
a) Dilute Hydrochloric acid is added to sodium sulfite solution and heated gently
b) Dilute sulfurous acid is added to dilute zinc chloride solution
c) A small amount of solid zinc oxide is added to dilute potassium hydroxide.
Question 2) A 2.557g sample of gas occupies 2.43 L at 1.62 atmospheres and 27.0 degrees C
a) Calculate the number of moles of gas present
b) The gas is known to be either hydrogen, helium, carbon dioxide, nitrogen, or methane. Using your answer to part (a), determine the identity of the gas.
Please help with any or all of it,
Thanks
