Determine the amount of sodium hypochlorite in Bleach you tolerated a 23.82 ml sample of 0.0100 M KIO cuboid with a solution of
Kisachek [45]

Answer: The moles of KIO cuboid titrated are 0.0002382

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

where,

n = moles of solute

V_s = volume of solution in ml

Now put all the given values in the formula of molarity, we get

0.0100=\frac{n\times 1000}{23.82}

n=0.0002382

Therefore, the moles of KIO cuboid are 0.0002382

What would be the bond order for He 2 2- molecule
LuckyWell [14K]

Answer:

In He2 molecule,

Atomic orbitals available for making Molecular Orbitals are 1s from each Helium. And total number of electrons available are 4.

Molecular Orbitals thus formed are:€1s2€*1s2

It means 2 electrons are in bonding molecular orbitals and 2 are in antibonding molecular orbitals .

Bond Order =Electrons in bonding molecular orbitals - electrons in antibonding molecular orbitals /2

Bond Order =Nb-Na/2

Bond Order =2-2/2=0

Since the bond order is zero so that He2 molecule does not exist.

A chemical lab has isolated a metallic element from a compound. The metal
trapecia [35]

Answer:

C. 1

Explanation:

Group 1 metals are highly reactive (such as Sodium) and form 1 to 1 ratio of ions with halogens (such as chlorine, bromine etc).

This happens because group 1 element can donate 1 valence electron to fulfill their octet rule and halogens can receive 1 valence electron to fulfill their octet.
