Is there a way of knowing the charges of transitional elements other than to memorize them?

Chemistry
1 answer:
romanna [79]2 years ago
3 0

Explanation:

To determine the charge on a given transition metal atom, you have to consider what element it is, the charges on the other atoms in the molecule, and the net charge on the molecule itself. The charges are always whole numbers, and the sum of all the atomic charges equals the charge on the molecule

dimulka [17.4K]

Answer:

The answer is: 7.7\times10^{10}

Explanation:

Scientific notation is of the kind: a.bc\times10^{x}

The given calculation:

7.0\times10^{3}\times1.1\times10^{7}=(7\times1.1)\times10^{(3+7)}

=7.7\times10^{10}

Therefore, the answer in scientific notation is: 7.7\times10^{10}

Gallium is produced by the electrolysis of a solution made by dissolving gallium oxide in concentrated NaOH(aq). Calculate the a
Snowcat [4.5K]

Answer:

Mass of Ga = 0.73694 gram

Explanation:

Given:

Current = 0.850 A

Time = 60 minutes

Find:

Amount of gas deposit.

Computation:

Total charge = Current × Time in second

Total charge = 0.850 × 60 × 60

Total charge = 3,060 C

Mole of electron = Total charge / Faraday constant         [Faraday constant = 96,485.3329]

Mole of electron = 3,060 / 96,485.3329

Mole of electron = 0.0317146

Moles of Ga = 1/3 [Mole of electron]

Moles of Ga = 1/3 [0.0317146]

Moles of Ga = 0.01057

Mass of Ga = molar mass × Moles of Ga

Mass of Ga = 69.72 × 0.01057

Mass of Ga = 0.73694 gram

Which is the best example of immiscible liquids?
Artist 52 [7]

The best example of immiscible liquids is

a polar liquid and a nonpolar liquid that do not dissolve into one another.

Explanation:

Immiscible averages that the fluids don't dissolve in each other – oil and water are an example. It is probable to swing up the juices and get them to mix but they soon separate. Departing immiscible liquids is done solely using a separating funnel.
