Ga2(CO3)3 is the formula.
<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.
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.
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

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

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

This implies that ,

Also,

This implies that,

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

This implies that,


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

This in implies that



Hence the fish tank can hold 0.857g water.
