Iodine is prepared both in the laboratory and commercially by adding Cl2(g) to an aqueous solution containing sodium iodide: 2Na
Oxana [17]

Answer: 65.7 gram

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} I_2=\frac{55.6g}{254g/mol}=0.219moles

2NaI(aq)+Cl_2(g)\rightarrow I_2(s)+2NaCl(aq)

According to stoichiometry :

1 mole of I_2 are produced by = 2 moles of NaI

Thus 0.219 moles of I_2 will be produced by =\frac{2}{1}\times 0.219=0.438moles of NaI

Mass of NaI=moles\times {\text {Molar mass}}=0.438moles\times 150g/mol=65.7g

Thus 65.7 g of NaI, must be used to produce 55.6 g of iodine

mastering biology ch 3 Water molecules have a polarity, which allows them to be electrically attracted to other water molecules
aniked [119]

Answer:

The answer to your question is: hydrogen bonding

Explanation:

Hydrogen bonding is a kind of interaction dipole-dipole, that means that 2 molecules attract each other because the have partial charges.

In the picture we can see 4 molecules of water, red circles are oxygens and white circles are hydrogens. In this bonding, Oxygen due to its size, and atomic number is more electronegative than hydrogen, then in water molecule is formed a partial negative charge in oxygen and a partial positive charge in hydrogen.

Finally, because of this partial charge, one oxygen can bond to one hydrogen of another molecule.

Arrange the following substances in order of decreasing magnitude of lattice energy. Rank the compounds in order of decreasing m
True [87]

The lattice energy of the compounds is distributed in the following decreasing order of magnitude: MgO > CaO > NaF > KCl.

<h3>KCl or NaF, which has a higher lattice energy?</h3>

The lattice energy increases with increasing charge and decreasing ion size.(Refer to Coulomb's Law.)MgF2 > MgO.Following that, we can examine NaF and KCl (both of which have 1+ and 1-charges), as well as atomic radii.NaF will have a larger LE than KCl since Na is smaller then K and F was smaller than Cl.

<h3>MgO or CaO, which has a larger lattice energy?</h3>

MGO is more difficult than CaO, hence.This is because "Mg" (two-plus) ions are smaller than "Ca" (two-plus) ions in size.MgO has higher lattice energy as a result.
