It is not balanced since there are 2 Cl molecules on the left side, and only 1 on the right side. In order to balance this, you would need to make sure there are the same amount of all the molecules on both sides...
4Na + 2Cl2 = 4NaCl
Hope this helps :)
Here’s what I found:
It takes very little energy to remove that outermost electron from an alkali metal. Thus, alkali metals easily lose their outermost electron to become a +1 ion. ... In fact, as you go down the 1A column, the first ionization energies get lower and lower, making cesium the most easily ionized element on the periodic table.
So basically it’s because part of what makes alkali metals so reactive is that they have one electron in their outermost electron layer.
Answer: option A) Mixtures may be composed of two or more elements, two or more compounds, or a combination of both.
Explanation:
A mixture is a combination of two or more substances mixed together and can be separated by physical methods.
A combination of two elements or compounds will yield chemical compounds NOT a mixture.
Thus, option A is false statement
