2Na+MGF2=2NAF+MG
I hope that's right :)
Answer:
2, 1, 1, 4.
Explanation:
Hello there!
In this case, for the given chemical reaction:

We can see how there is one SO4 on the left and two on the right, thus, we add a 2 in front of H2SO4:

Next, since there are 8 atoms of hydrogen on the left and two on the right, we add a 4 in front of H2O to obtain:

Which is now balanced so the coefficients 2, 1, 1, 4.
Best regards!
From the calculation, the molar mass of the solution is 141 g/mol.
<h3>What is the molar mass?</h3>
We know that;
ΔT = K m i
K = the freezing constant
m = molality of the solution
i = the Van't Hoft factor
The molality of the solution is obtained from;
m = ΔT/K i
m = 3.89/5.12 * 1
m = 0.76 m
Now;
0.76 = 26.7 /MM/0.250
0.76 = 26.7 /0.250MM
0.76 * 0.250MM = 26.7
MM= 26.7/0.76 * 0.250
MM = 141 g/mol

The harmonic law would suggest that Neptune will take a longer amount of time to orbit the sun than Mercury. That's what I think anyways
