Consider the electrolysis of molten barium chloride (bacl2). (a) write the half-reactions. include the states of each species..
IrinaK [193]

<span>Molten barium chloride is separetes:</span><span>
BaCl</span>₂(l) → Ba(l) + Cl₂(g), <span>
but first ionic bonds in this salt are separeted because of heat: 
BaCl</span>₂(l) → Ba²⁺(l) + 2Cl⁻(l).

Reaction of reduction at cathode(-): Ba²⁺(l) + 2e⁻ → Ba(l).

Reaction of oxidation at anode(+): 2Cl⁻(l) → Cl₂(g) + 2e⁻.

The anode is positive and the cathode is negative.

Select the appropriate statements and arrange them in a logical order to explain the bonding in BeF2. i. Each of the singly occu
galina1969 [7]

Answer:

e.iv, iii, i, ii

Explanation:

Be has electron configuration of 1s^2 2s^2. During bond formation, one 2s electron is promoted to a 2p orbital. Hence two hybrid sp beryllium orbitals are formed. These two hybrid orbitals are used in sigma bond formation to fluorine atoms.

Recall that fluorine has filled 2p orbitals containing lone pairs of electrons. These filled orbitals can interact with the unhybridized 2p-orbitals on beryllium to form pi bonds. This is the reason for the sequence of events chosen in the answer.

Given the following information:
Katyanochek1 [597]
Step by Step Explanation

From the question,
the dimensions of the tank are;

L = 30 cm, way =0.075m and H = 15 cm

The density of water is given as
D = 1g {cm}^{ - 3}

The unit of density given in the question means that the mass of the water is in grams and the volume should also be in
{cm}^{3}

To find the volume of the water, we first convert the units of dimensions given in inches and metres to centimetres

1 inch = 2.54 cm

This implies that ,

H=15 inches=15×2.54cm=38.1cm

Also,

100cm=1m

This implies that,
w= \frac{0.075}{100 } = 7.5 \times {10}^{ - 4} cm

Now, the volume of water in the tank can hold, can be found from the relation;

V=L\times W\times H

This implies that,

v = 30cm \times (7.5 \times {10}^{ - 4} )cm \times 38.1cm

v = 0.857 {cm}^{3} \: to \: 3 \: d.p

Finally, we can calculate the mass of the water from the relation given;

D=\frac{M}{V}

This in implies that

1g {cm}^{ - 3} = \frac{m}{0.857 {cm}^{3} }
m = 1g {cm}^{ - 3} \times 0.857 {cm}^{3}
m = 0.857g


Hence the fish tank can hold 0.857g water.
