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 happens when HCl gas is passed through a saturated PbCl2 solution?

VikaD [51]

When HCl is added to a saturated solution of PbCl2, the solubility of PbCl2 would decrease so precipitation would occur. The decrease in the solubility is due to the common ion effect or the presence of Cl- ions in both compounds.

Rank the species CH2NH, CH3I, HF, C2H6 from most to least miscible in ammonia (NH3) 1. CH3I > C2H6 > HF > CH2NH 2. CH2N

777dan777 [17]

Answer:

$HF>CH_{2}NH>CH_{3}I>C_{2}H_{6}$

Explanation:

$NH_{3}$ is an weak base. HF is an weak acid. Hence an acid-base reaction will ocuur between $NH_{3}$ and HF resulting a homogeneous mixture.

$NH_{3}$ is a polar protic molecule. Hence it can form hydrogen bonding with another polar protic molecule $CH_{2}NH$ . Also dipole-dipole attraction force along with london dispersion force exists between $CH_{2}NH$ and $NH_{3}$ .

$CH_{3}I$ is a polar molecule. Hence only dipole-dipole attraction force along with london dispersion force operates between $CH_{3}I$ and $NH_{3}$ .

$C_{2}H_{6}$ is a non-polar molecule. Hence only london dispersion force exists between $C_{2}H_{6}$ and $NH_{3}$ .

So, order of miscibility: $HF>CH_{2}NH>CH_{3}I>C_{2}H_{6}$

(most) (least)

Find the number of atom in 1.50g of c

Aleonysh [2.5K]

Atomic mass Carbon (C ) = 12.01 a.m.u

12.01 g ---------- 6.02x10²³ atoms
1.50 g ----------- ??

1.50 x ( 6.02x10²³ ) / 12.01 =

7.51x10²² atoms of C

hope this helps!
