Answer:

Due to presence of unpaired electrons in outermost shell of oxygen, oxygen is a fairly reactive element while neon is not.

Explanation:

Lets look at the electronic configuration of both the elements.

Oxygen, a chalcogen, has EC as = $1s^{2}2s^{2}2p^{4}$

while, for Neon, a noble gas, EC is = $1s^{2}2s^{2}2p^{6}$

In neon, the outermost orbital p is completely filled while in oxygen it is partially filled, with 2 unpaired electrons.

<em>Thus the completely filled orbitals give extra stability to neon and thus less reactivity. In other case, oxygen has 2 unpaired electrons, unstable and has exchange energy, making it more reactive.</em>

Thus, oxygen is a fairly reactive element while neon is not..

how many grams of silver medal could be recovered from a reaction of 50 g silver nitrate and copper metal

Likurg_2 [28]

Answer:

Answer is: mass of copper is 127 grams.

Balanced chemical reaction: Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s).

m(Ag) = 432 g.

n(Ag) = m(Ag) ÷ M(Ag).

n(Ag) = 432 g ÷ 108 g/mol.

n(Ag) = 4 mol.

From chemical reaction: n(Ag) : n(Cu) = 2 : 1.

n(Cu) = 4 mol ÷ 2 = 2 mol.

m(Cu) = n(Cu) · M(Cu).

m(Cu) = 2 mol · 63.5 g/mol.

m(Cu) = 127 g

Which salt is produced when NH4OH Reacts with HNO3

borishaifa [10]

Explanation:

When an acid reacts with a base then it results in the formation of salt and water.

$HNO_{3}$ is an acid and $NH_{4}OH$ is a base thus, when we dissolve ammonium hydroxide in nitric acid then it results in the formation of ammonium nitrate and water.
