For each of the following balanced equations, calcu- late how many grams of each product would form if 12.5 g of the reactant listed first in the equation re- acts completely (there is an excess of the second re- actant). a. SiC(s)+2Cl2(g)=SiCl4(l)+C(s)​ b. Li2O(s)+H2O(l)=2LiOH(aq)
c.2Na2O2(s)+2H2O(l)=4NaOH(aq)+O2( g)
d. SnO2(s)+2H2(g)=Sn(s)+2H2O(l)

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
