List the correct balanced coefficients for the following reaction :
HF+Ca3(PO4)2>CaF2+H3(PO4)\mathrm{HF}+\mathrm{Ca}_{3}\left(\mathrm{PO}_{4}\right)_{2}-->\mathrm{CaF}_{2}+\mathrm{H}_{3}\left(\mathrm{PO}_{4}\right) A) 3,1,3,13,1,3,1
B) 6,2,3,26,2,3,2
C) 12,2,6,412,2,6,4
D) 3,1,3,23,1,3,2
E) 6,1,3,26,1,3,2

STEP 1

1. The chemical equation given is:
$$ \mathrm{HF} + \mathrm{Ca}_{3}\left(\mathrm{PO}_{4}\right)_{2} \rightarrow \mathrm{CaF}_{2} + \mathrm{H}_{3}\left(\mathrm{PO}_{4}\right)
\] 2. We need to balance the equation by ensuring the same number of each type of atom on both sides of the equation.

STEP 2

1. Identify the number of each type of atom in the reactants and products.
2. Balance the equation by adjusting coefficients.
3. Verify that the equation is balanced.

STEP 3

Identify the number of each type of atom in the reactants and products.
- Reactants:
- HF\mathrm{HF}: 1 H, 1 F
- Ca3(PO4)2\mathrm{Ca}_{3}\left(\mathrm{PO}_{4}\right)_{2}: 3 Ca, 2 P, 8 O
- Products:
- CaF2\mathrm{CaF}_{2}: 1 Ca, 2 F
- H3(PO4)\mathrm{H}_{3}\left(\mathrm{PO}_{4}\right): 3 H, 1 P, 4 O

STEP 4

Balance the equation by adjusting coefficients.
- Start by balancing the calcium (Ca\mathrm{Ca}) atoms:
- Reactants have 3 Ca from Ca3(PO4)2\mathrm{Ca}_{3}\left(\mathrm{PO}_{4}\right)_{2}.
- Products have 1 Ca in CaF2\mathrm{CaF}_{2}.
- Place a coefficient of 3 in front of CaF2\mathrm{CaF}_{2}:
$$ \mathrm{HF} + \mathrm{Ca}_{3}\left(\mathrm{PO}_{4}\right)_{2} \rightarrow 3\mathrm{CaF}_{2} + \mathrm{H}_{3}\left(\mathrm{PO}_{4}\right)
\] - Balance the fluorine (F\mathrm{F}) atoms:
- Products now have 6 F (from 3 CaF2\mathrm{CaF}_{2}).
- Reactants have 1 F in HF\mathrm{HF}.
- Place a coefficient of 6 in front of HF\mathrm{HF}:
$$ 6\mathrm{HF} + \mathrm{Ca}_{3}\left(\mathrm{PO}_{4}\right)_{2} \rightarrow 3\mathrm{CaF}_{2} + \mathrm{H}_{3}\left(\mathrm{PO}_{4}\right)
\] - Balance the hydrogen (H\mathrm{H}) atoms:
- Reactants now have 6 H (from 6 HF\mathrm{HF}).
- Products have 3 H in H3(PO4)\mathrm{H}_{3}\left(\mathrm{PO}_{4}\right).
- Place a coefficient of 2 in front of H3(PO4)\mathrm{H}_{3}\left(\mathrm{PO}_{4}\right):
$$ 6\mathrm{HF} + \mathrm{Ca}_{3}\left(\mathrm{PO}_{4}\right)_{2} \rightarrow 3\mathrm{CaF}_{2} + 2\mathrm{H}_{3}\left(\mathrm{PO}_{4}\right)
\] - Balance the phosphorus (P\mathrm{P}) and oxygen (O\mathrm{O}) atoms:
- Reactants have 2 P and 8 O from Ca3(PO4)2\mathrm{Ca}_{3}\left(\mathrm{PO}_{4}\right)_{2}.
- Products have 2 P and 8 O from 2 H3(PO4)\mathrm{H}_{3}\left(\mathrm{PO}_{4}\right).

SOLUTION

Verify that the equation is balanced.
- Reactants: 6 H, 6 F, 3 Ca, 2 P, 8 O
- Products: 6 H, 6 F, 3 Ca, 2 P, 8 O
The equation is balanced.
The correct balanced coefficients are: 6,1,3,2\boxed{6, 1, 3, 2}
