PLEASE HELP ME ASAP For reaction below, describe how its equilibrium could be shifted in the indicated direction.

1. H2(g)+C12(g)<>2HC1(g)+thermal energy: shift to the left

2.C(s) +O2(g)<>CO2+thermal energy: shift to the right

You are to give ampicillin with a recommended dose of 25mg/kg to a child with a mass of 29kg. if stock on hand is 250mg/capsule how many capsules should be given?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.

What is the average rate of the reaction between 10 and 20 s?
