Because neither can be created or destroyed
Answer:
a. The central atom is sulfur
b. SF2
c. The central atom has two lone pairs
d. The ideal angle between the sulfur-fluorine bonds is 109.5°
e. I expect the actual angle between the sulfur-fluorine bonds to be less than 109.5° because unbonded pairs repel bonded pairs more than bonded pairs repel other bonded pairs. So the bonds here will be pushed closer than normal
Answer:
3Ag^(+) + 3Cl ^(-) --> 3AgCl (s)
Explanation:
Full ionic equation:
3Ag^(+) + 3NO3^(-) + Al^(+3) + 3Cl^(-)-->
3AgCl (s) + Al^(3+) + 3NO3^(-)
Spectator ions 3NO3^(-) & Al^(+3) can be left out in the net ionic equation.
Answer: The mole ratio of 
to 
is 1: 1
Explanation:
According to the balanced chemical equation ,the number of atoms of each element has to be same on reactant and product side. The stoichiometric coefficients of the species represent their number of moles.
Thus in the reactants, there is 1 mole of and 1 mole of 
molecule. And thus there is 1 mole of in the product as well.
Thus the mole ratio of to is 1: 1
