Answer:
Elements in the same vertical column on the periodic table will have similar chemical properties and behave similarly in chemical reactions. These vertical columns can also be called groups/families.
Explanation:
Answer : The mass of calcium chloride is, 116.84 grams
Solution : Given,
Molar mass of calcium chloride,
= 110.98 g/mole
Number of molecules of calcium chloride = 
As we know that,
1 mole of calcium chloride contains
molecules of calcium chloride
or,
1 mole of calcium chloride contains 110.98 grams of calcium chloride
Or, we can say that
As,
molecules of calcium chloride present in 110.98 grams of calcium chloride
So,
molecules of calcium chloride present in
of calcium chloride
Therefore, the mass of calcium chloride is, 116.84 grams
Answer is (1) - no reaction.
<em>Explanation;
</em>
Some of you may think this reaction as a single replacement reaction which gives NaBr + F₂ as products.
But, according to the reactivity of the halogens, reactivity decreases from up to bottom of the group. F is placed above Br. Hence, F is more reactive than Br. Hence, Br can't replace F.
