Zn + 2 hcl zncl2 + h2 you are asked the following question: in the chemical reaction above, if you start with 100 grams of zinc, how many moles of hydrogen will be produced? what is the logical first step to solving this problem?

given: 100 grams of zinc.the logical first step would be to convert 100 grams of zinc into moles.the molar mass of zinc is  65.38 g/mol.using dimensional analysis:     from the balanced chemical equation, we see that there is 1 mole of  for every mole of  .since this is a 1: 1 ratio, there will be about 1.53 moles of hydrogen produced.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
