Given the chemical equation: 2 ca + o 2 → 2 cao, if 2 moles of cao are formed in this reaction, then 2 moles of o 2 must have reacted. true false

FALSE

Look at the stoichiometry from the reaction

Explanation:

2Ca + O₂ → 2 CaO

When we have this reaction, it means that 2 moles of calcium react with 1 mol of oxgen for the production of 2 moles calcium oxide.

So, If we produced 2 mol of CaO it would has reacted 1 mol of O₂

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.
