Explanation:
The results shows the reactivity of the halogens and how they displace one another from any solution of their compounds.
The oxidizing power of the halogens decreases from top to down on the group. This explains why the more powerful oxidizing halogens displaces the less powerful one from simple salts.
We see that chlorine is able to displace Bromine and iodine
Bromine is only able to displace Iodine
Iodine cannot displace bromine or chlorine
Answer:
Will group 2 elements lose electrons to bond with nonmetals in group 17 in a
1:2 ratio?
Explanation:
Metals are electropositive in nature. This means that they loose electrons. Thus, metals form ionic bonds by loosing electrons to non metals.
Elements of group 2 have a valency of 2 while those of group 17 has a valency of 1 so the ratio in which group 2 elements bond with elements of group 17 is 1:2. Hence the answer.
Answer:
2.20 x 10²⁵ atoms
Explanation:
Atoms of CO= 36.6-mol sample
From Avogadro's constant, which is
(6.022 × 10^ 23 atoms per mole)
Then
Number of atoms=[ 6.022 × 10^ 23 atoms/mole] × [36.6-mol]
= 2.20 x 10²⁵ atoms
Hence, number of atom is 2.20 x 10²⁵ atoms
