Consider the chemical equation below. If you are given 2 mols of HCl and 5 mols of Zn, what is the maximum amount of zinc chloride that can be
produced? Show your work for full credit.
Zn + 2 HCl → ZnCl2 + H2

What is the temperature of one mole of helium gas at stp?

What is the mass of 0.46 mol of mgcl2

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
