Explain how magnesium is produced at the negative electrode in experiment 1.
The liquified (/molten) MgCl₂ dissociates into Mg²⁺ and Cl⁻ ions;
The Cl⁻ ions are drawn to the positive electrode (which has a deficit of electrons) where they deposit electrons since they are negatively charged;
This yields Cl atoms (these will form Cl₂ gas by covalent bonding and bubbles will be seen as this gas rises out of the liquid and it will enter the air);
These electrons will flow from the positive electrode to the negative electrode;
The Mg²⁺ ions, conversely, will be drawn to the negative electrode or cathode (which has a surplus of electrons partly from those the Cl⁻ ions lose) where they pick up electrons since they have a positive charge;
This yields pure magnesium.
The magnesium has been produced with the application of electric current for the production of ions that accumulate at the electrodes.
The setup has been for the electrochemical process. The sample in the molten state has been applied with the electric current. The current results in the dissociation of the sample into ionic constituents.
The opposite charge attracts negative charge. Thus, the negative ion moves towards the positive electrode, and negative ion move towards the positive electrode. The accumulation of ions has been obtained from the electrodes.
The magnesium chloride under the influence of electric field has been converted into the positive Mg ions and negative Cl ions. The positive Mg ion will move towards the negative electrode, and thus Mg has been produced.

ROUND FINAL ANSWER TO 2 DECIMAL PLACES AND DO NOT INCLUDE A UNIT 675 mL of a gas at a pressure of 1.5atm is compressed to 345 mL. What is the new pressure of the gas?
This problem is providing the initial volume and pressure of a gas as 675 mL and 1.5 atm and then mentions the final volume as 345 mL and asks for the new pressure of the gas.
Thus, we start off this problem by recalling the concept of Boyle's law as an inversely proportional relationship between pressure and volume:
[tex]P_1V_1=P_2V_2[/tex]
In which we solve for the final pressure, [tex]P_2[/tex] as shown below:
[tex]P_2=\frac{P_1V_1}{V_2} \\\\\\P_2=\frac{675mL*1.5atm}{345mL} \\\\\\P_2=2.93atm[/tex]
Considering we had to cancel out the milliliters to obtain atm as units of pressure.

T or F: Lone pairs around the oxygen atom of a water molecule play no role in determining its molecular geometry?
Answer:
Explanation:
They play a very important part. The geometry is not a straight line. It is an angle over 90 which means that the molecule has the same general shape as a boomerang. The two hydrogens and the 2 lone electron pairs try to get away as far as possible from each other. The actual shape results in a tetrahedron shape. But the two hydrogens and 1 oxygen actually look like the aforementioned boomerang.

Given that E°red = -0.40 V for Cd2+/Cd at 25°C, find E° and E for the concentration cell expressed using shorthand notation below.
Cd(s) ∣ Cd2+(1.0 × 10-5 M) ∣∣ Cd2+(0.100 M) ∣ Cd(s)
E° = 0.00 V and E = +0.12 V
E° = 0.00 V and E = +0.24 V
E° = -0.40 V and E = -0.16 V
E° = -0.40 V and E = -0.28 V
From the information in the question, the E° and E for the cell is 0.00 V and 0.12 V.
Using the Nernst equation;
Ecell = E°cell - 0.0592/n log Q
We know that E°cell = 0.00 V since the anode and cathode are both made up of cadmium.
Substituting the given values into the Nernst equation;
Ecell = 0.00 V - 0.0592/2 log (1.0 × 10-5 M/0.100 M)
Ecell = 0.00 V - 0.0296 log(1 × 10^-4)
Ecell = 0.12 V

When a substance changes from a solid to a liquid, is a new substance made?
Answer:
no
Explanation:
it means melting or fusion so yhe answer is no
A substance changes from a solid to a liquid no its is not the formation of new substance. It is the change of state of the matter.
What are the states of matter?The states of matter can be defined as one of the several configurations in which matter can exist.
There are basically three states of matter.
Solid - It is defined as hard, distinct in volume and shape. Atoms and molecules are joined together to form solids.Liquid - It is defined as defined volume with the ability to flow and change shape. Atoms and molecules are only weakly bound together in liquids.Gases - It is defined as no clear shape or volume.Thus, a substance changes from a solid to a liquid no its is not the formation of new substance. It is the change of state of the matter.

If i initially have a gas with a pressure of 84 kpa and a temperature of 350 c and i heat it an additional 230 degrees, what will the new pressure be? assume the volume of the container is constant.
Answer:
67.824
Explanation: You want to use the combined gas law equation (P1*V1)/(n1*T1)=(P2*V2)/(n2*T2). So first cross out what remains constant, so volume(V) and I assume moles (since it was not mentioned as a change). Then you can solve algebraically for the answer!
Hope this helped!
The new pressure will be 139.2 kpa .
What is the combined Gas Law?According to combined gas law,
[tex]\rm\dfrac{PV}{nT} = R[/tex]
In the Combined Gas Law,if we change either one of the variables the others will also change.
When the moles of the gas is constant , the above equation can be written as ,
[tex]\rm \dfrac{P'V'}{T'}= \dfrac{PV}{T}[/tex]
Given is P = 84kpa , T= 350⁰ C and T' = 350+230=580⁰ C , V=V' , P'=?
So we will substitute the values in the above formula keeping volume constant.
[tex]\rm \dfrac{P'}{T'}= \dfrac{P}{T}[/tex]
[tex]\rm\dfrac{P'}{580}= \dfrac{84}{350}[/tex]
[tex]\rm P' = \dfrac{84\times 580}{350}[/tex]
[tex]\rm P'= 139.2 \;kpa[/tex]
Therefore the new pressure will be 139.2 kpa .

A sample of gas is at 78.0 oC. You want to change the volume of the gas from 1.60 L to 0.425 L under constant pressure. What must you do to the temperature of the gas
Answer:
the rule is V1/T1= V2/T2
so we convert the T1 from °c to kelvin
78+273.15= 351.15 k
1.60/351.15 = 0.425/T2
4.55 ×10-³ = 0.425/T2
then T2 = 93.40 kelvin
hence, we should decrease the temperature

Molarity of Mg(CN)₂ = 0.075 M
Mole of Mg(CN)₂ =?Mole = Molarity x Volume
Mole of Mg(CN)₂ = 0.075 × 0.275
Mole of Mg(CN)₂ = 0.020625 mole
Finally, we shall determine the mass of Mg(CN)₂Mole of Mg(CN)₂ = 0.020625 mole
Molar mass of Mg(CN)₂ = 24 + 2(12 + 14) = 76 g/mol
Mass of Mg(CN)₂ =?Mass = mole × molar mass
Mass of Mg(CN)₂ = 0.020625 × 76

From the question given above, the following data were obtained:
Initial volume (V₁) = 4 L
Initial temperature (T₁) = 300 K
Initial pressure (P₁) = 1 atm
Final temperature (T₂) = 600 K
Final volume (V₂) = 2 L
