I believe the correct answer from the choices listed above is the third option. A mixture of uneven distribution and easy separation is called heterogeneous solution. It <span> is made of different substances that remain physically separate. Hope this answers the question.</span>

The solutes dissolves in solvent results in the formation of a solution.

Those mixtures in which the components of mixture are uniformly distributed throughout the mixture are said to be homogeneous.

Those mixtures in which the components of mixture are not uniformly distributed throughout the mixture are said to be heterogeneous.

Those solutions whose concentrations are accurately known are known as standard.

Hence, a mixture of uneven distribution and easy separation is heterogeneous.

The reaction of nitrogen dioxide with fluorine

andrew-mc [135]

Answer:

Rate = 0.001615 Ms-1

Explanation:

2 NO2 + F2 --> 2 NO2F

The reaction is first order with respect to NO2 and also first order with respect to F2.

The rate law is given as;

Rate = k [NO2] [ F2]

k = 1.58E-4 M-1s-1

[NO2] = 2.84 M

[F2] = 3.60 M

Rate = ?

Inserting the values into the equation, we have;

Rate = 1.58E-4 * 2.84 * 3.60

Rate = 0.001615 Ms-1

If you have 155 mL solution of a 0.762 M FeCl3 solution, how many

Sedaia [141]

Moles are the product of the molar concentration and the volume of the solution. The moles of Ferric chloride is 0.118 moles.

<h3>What are moles?</h3>

Moles are the smallest unit of the measurement of atoms and molecules. It is calculated by the molar concentration and the volume of the solution.

Given,

Molar concentration of ferric chloride = 0.762 M

Volume of solution = 0.155 L

Moles are calculated as:

$\begin{aligned} \rm Moles &= \rm Molarity \times Volume (L) \\\\&= 0.762 \times 0.155\\\\&= 0.118\;\rm mol\end{aligned}$

Therefore, 0.118 moles of ferric chloride are present in the sample.

In 1901, Thomas Edison invented the nickel-iron battery. The following reaction takes place in the battery. Fe(s) + 2 NiO(OH)(s)

lord [1]

Ans: Moles of Fe(OH)2 produced is 5.35 moles.

Given reaction:

Fe(s) + 2NiO(OH) (s) + 2H2O(l) → Fe(OH)2(s) + 2Ni(OH)2(aq)

Based on the reaction stoichiometry:

1 mole of Fe reacts with 2 moles of NiO(OH) to produce 1 mole of Fe(OH)2

It is given that there are:

5.35 moles of Fe

7.65 moles of NiO(OH)

Here the limiting reagent is Fe

Therefore, number of moles of Fe(OH)2 produced is 5.35 moles.

30 pts! Sodium and water react according to the following equation. If 31.5g of sodium are added to excess water, how many liter

mihalych1998 [28]

First, calculate the number of moles of sodium present with the given mass,

31.5 g of sodium x (1 mol sodium/ 23 g sodium) = 1.37 mol sodium

It is given in the equation that for every 2mols of sodium, one mol of H2 is produced.

mols of H2 = (1.37 mols sodium)(1 mol H2/ 2 mols sodium)
mols of H2 = 0.685 mols H2

Then, at STP, 1 mol of gas = 22.4 L.

volume of H2 = (0.685 mols H2)(22.4 L / 1 mol)
volume of H2 = 15.34 L

Answer: 15.34 L

What is the mass (g) of a 17.4 mL piece of material, if the density is 3.4 g/mL?

natima [27]

Answer:

59.16 g

Explanation:

Mass = Density × Volume

= 3.4 g/mL × 17.4 mL

= 59.16 g or

59.2 g (rounded to three significant figures) or

59 g (rounded to two significant figures)

Hope that helps.
