Answer:

Electronic configuration of Ga³⁺:

Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰ 3d¹⁰ 4p⁰

Explanation:

Gallium is present in group 13.

It has 3 valance electrons.

Electronic configuration:

Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p¹

There are two possibilities of gallium to form cation.

By removing one 4p electron to form Ga +1 cation.

By removing two 4s electrons and one 4p to form Ga +3 cation.

Gallium is preset in group thirteen that's why common oxidation state is +3.

Electronic configuration of Ga⁺:

Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁰

Electronic configuration of Ga³⁺:

Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰ 3d¹⁰ 4p⁰

_____?or current flow, can be thought of as a faucet being turned on and water flowing.

HACTEHA [7]

Answer: Circuit Flow

Explanation:

Water flowing though pipes is an analogy often used to help us understand Electrical Circuit flow. The pipe is like the wire in the electric circuit. The pump is like the battery. The generated pressure of the pump pushes water through the pipe, just as the voltage pushes electrons through the circuit. I will attach an image so you can visualize what I wrote. :)

How many moles of TNT would be detonated if you used 539.88 grams of TNT? The structure of TNT is C7H5N3O6. Round your answer to

Kruka [31]

Answer:

Moles of TNT = 2.38 moles

Explanation:

First , calculate the molar mass of the compound TNT

The formula is : C7H5N3O6

How to calculate molar mass?

Molar mass : It is the mass of substance in grams which is present in 1 mole of the compound.It is calculated by:

Molar mass = Number of atoms x the atomic mass of the element

Atomic mass of the elements are given below :

C = 12.0107

H = 1.0079

N = 14.0067

O = 15.9994

Molar mass of C7H5N3O6 =

= (7 x C) + (5 x H) + (3 x N) + (6 x O)

= 7(12.0107) +5(1.0079) + 3(14.0067) + 6(15.9994)

Molar mass = 227 .13 gram/mole

Mole are calculated using the formula:

$Moles =\frac{given\ mass}{Molar\ mass}$

Given mass = 539.88 grams

Molar mass = 227.13 g/mole

$Moles =\frac{539.88}{227.13}$

= 2.3769

Moles = 2.38 moles

Which of these statements describes this mathematical equation?

salantis [7]

Answer:

The final pressure of a gas is inversely proportional to the volume change and directly proportional to temperature

Explanation:

Given

$\frac{P_1V_1}{T_1} = k$

Required

Interpret

$\frac{P_1V_1}{T_1} = k$

Multiply both sides by T1

$T_1 * \frac{P_1V_1}{T_1} = k * T_1$

$P_1V_1 = kT_1$

Divide both sides by V1

$\frac{P_1V_1}{V_1} = \frac{kT_1}{V_1}$

$P_1 = \frac{kT_1}{V_1}$

This can be rewritten as:

$P_1 = k\frac{T_1}{V_1}$

In the above expression; k is a constant of proportionality.

So, the equation can be written as variation as follows:

$P_1\ \alpha\ \ \frac{T_1}{V_1}$

To interpret:

<em>P varies directly to T (the numerator) and inversely to V (the denominator).</em>

A solid with a mass of Mgrams is melted by heating it. After a half-hour, the solid is

Lerok [7]

Answer:

equal to M

Explanation:

The mass of the fully melted mass and the initial solid will be the same. So, the mass of the melt is equal to M.

Mass is the amount of matter contained within a substance. Since only the phase changed and the amount of matter is still the same, the mass of the molten phase and the solid phase will remain the same.

We are correct to say that in the heating process no mass was destroyed or added in melting the solid.

A simple phase change that preserved the mass only occurred.

A container of gas has a volume of 3.5 L and a pressure of 0.8 atm. Assuming the temperature remains constant, what volume of ga

vovikov84 [41]

<h3>Answer:</h3>

5.6 L

<h3>Explanation:</h3>

We are given;

Initial volume, V1 = 3.5 L
Initial pressure, P1 = 0.8 atm
Final pressure, P2 = 0.5 atm

We are required to calculate the final volume;

According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature.

That is; P α 1/V
Mathematically, P=k/V
At two different pressure and volume;

P1V1 = P2V2

In this case;

Rearranging the formula;

V2 = P1V1 ÷ P2

= (0.8 atm × 3.5 L) ÷ 0.5 atm

= 5.6 L

Therefore, the resulting volume is 5.6 L
