Answer:
The balanced equation must be:
2Na + MgF₂ → 2NaF + Mg
Explanation:
You see that you have 2F in the reactant side, that's why we add 2, to the stoichiometry of the sodium fluoride.
So now, we have 2 moles of NaF. Therefore we need to add 2 to the sodium on the reactant side.
The equation is now balanced.
2 Na reactant side → 2 Na product side
1 Mg reactant side → 1 Mg product side
2 F product side → 2 F product side
It would use rapid combustion
<h2>Answer:</h2>
The physical properties of a solution and the properties of the individual components are <u>_Different___.</u>
<h3>Explanation:</h3>
Physical properties are the structure, melting point , boiling point freezing point etc.
These properties of an individual compound if different when it is present in the solution.
For example salt which is NaCl has physical present in the solution as compare to solid form.
When a salt is added to the water, the boiling point and freezing point of water is changed from the pure form of water.
Efforts to control kudzu infestations have included the following methods: cutting, grazing, digging, disking, prescribed burning and application of herbicides. Roots of mature plants grow too deeply to be affected by freezing. Burning will kill only the very young plants.
Ideally, simply pulling out the heavy vines would prevent the kudzu from returning. However, you still need to kill each of the rooted stems at their crowns. Mowing or cutting back the vegetation to the ground provides the first step in removal. Then it’s time to bring out the big guns in the form of chemical herbicides.
