Answer:

2Na + MgF₂   → 2NaF  + Mg

Explanation:

Chemical equation:

Na + MgF₂   →  NaF  + Mg

Chemical equation:

2Na + MgF₂   → 2NaF  + Mg

The given reaction follow the law of conservation of mass because there are equal number of atoms of sodium, magnesium and fluorine are present on both side of equation.

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

Type of reaction:

The given chemical reaction is type of single replacement reaction. Sodium replace the magnesium and form sodium fluoride.

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Another chem question I need help with (multiple choice)
Andreyy89

Answer:

The answer to your question is letter B, 2-methylhexane.

Explanation:

Remember that for naming organic compounds first, we need to look for the largest chain of carbons.

In your example, the largest chain is horizontal and has 6 carbons.

Later, we need to circle all the branches, in your example there is only one branch located close to the left side

After that, we number the carbons of the main chain, starting in the corner with more branches, in your example we start from the first carbon on the left.

Finally, start naming the number of the carbon branch, later hte name of the branch and finally the name of the main chain.
