Balance each equation by entering the correct coefficients. 1. _SiO2 + _CaC2 ->_Si + _CaO + _CO2

2. _NH3 +_O2 -> _NO + _H2O

The balanced chemical equation for this lab is: 3cucl2(aq) + 2al(s) 3cu(s) + 2alcl3(aq) if 10.5 g copper chloride react with 12.4 g aluminum, what is the limiting reactant?

When determining the shape of a molecule, it is important to draw a lewis dot structure first in order to see the total number a. electrons within the moleculeb. bonding and unshared pairs around central atomc. unshared pair within the molecule( i really need it )
