Explanation:
MgF₂ + ___Li₂CO₃ → ___MgCO₃ + ___LiF
1. Every chemical reactions obey the law of conservation of matter. The law states that "matter can neither be created not destroyed but transformed from one form to another".
When chemical reactions are balanced, they simply obey the law of conservation of matter and mass. This makes makes measurement easy to make when carrying out experiments. One can easily deduce the amount of reactants to be used and the products expeceted
2 MgF₂ + ___Li₂CO₃ → ___MgCO₃ + ___LiF
to balance the equation:
- check if the equation is balanced.
- Put a,b,c and d before each of the products and reactants.
aMgF₂ + bLi₂CO₃ → cMgCO₃ + dLiF
- The coefficients are needed to balance the equation:
conserving Mg: a = c
F: 2a = d
Li: 2b = d
C: b = c
O: 3b = 3c
let us assume that a=1
then c = 1
b = 1
d =2
MgF₂ + Li₂CO₃ → MgCO₃ + 2LiF

Explanation:
In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.
If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.
Answer: Why is Dalton credited with proposing the first atomic theory if Democritus was talking about atoms almost 2,200 years earlier? because
- Democritus' ideas were not supported by evidence.
- Dalton's theory was the first scientific theory because it relied on scientific investigative processes.
- Dalton's theory was supported by evidence and repeated investigation.

Answer:
Saturn
Saturn has overtaken Jupiter as the planet with the most moons, according to US researchers. A team discovered a haul of 20 new moons orbiting the ringed planet, bringing its total to 82; Jupiter, by contrast, has 79 natural satellites
