Sodium phosphate has a chemical formula
Na2PO4
Calculating the concentration of sodium phosphate given a concentration of sodium ions can be done using dimensional analysis
0.60 moles/L Na+ (1 mole Na2PO4 / 2 moles Na+) = 0.30 moles/L Na2PO4
= .030 M Na2PO4
Answer:
It predicts whether or not a reaction will be spontaneous.
Explanation:
The equation;
∆G= ∆H - T∆S enables us to obtain the Gibbs free energy of a chemical process.
The Gibbs free energy value tells us whether a chemical process will be spontaneous or not.
When;
∆G>0 the reaction is not spontaneous
∆G=0 the reaction is at equilibrium
∆G<0 the reaction is spontaneous
Answer:
Single replacement reaction
Explanation:
It's already balanced so it would just be Mg + H2SO4 --> H2 + MgSO4
The formula for a single replacement reaction is
A + BC --> B + AC
A=Mg
B=H2
C=SO4
it is either "aweak acid or a lousy (or very weak) acid"
