An electrochemical cell operates because the electrodes in the two half-cells differ in their electrical potential. A metal electrode composed of ______ reducing agent will have a greater electrical potential to push electrons toward the electrode composed of a ______ reducing agent.
A metal electrode composed of strong reducing agent will have a greater
electrical potential to push electrons toward the electrode composed of a
weak reducing agent.
Strong reducing agents are compounds which donates or loses electrons
with a corresponding increase in the oxidation state. Weak reducing agents
can also be referred to as oxidizing agents and they accept the electrons
from the strong reducing agents which results in a reduction in the oxidation
state.
The strong reducing agent has a greater electric potential which aids the
electrons being pushed towards the electrodes with a weak reducing agent.

how does water's structure explain its properties?
We know that water is tasteless, odorless, and transparent. In small quantities, it is also colorless. However, when a large amount of water is observed, as in a lake or the ocean, it is actually light blue in color. The blue hue of water is an intrinsic property and is caused by selective absorption and scattering of white light. These and other properties of water depend on its chemical structure.The transparency of water is important for organisms that live in water. Because water is transparent, sunlight can pass through it. Sunlight is needed by water plants and other water organisms for photosynthesis.Chemical Structure of WaterEach molecule of water consists of one atom of oxygen and two atoms of hydrogen, so it has the chemical formula H2O. The arrangement of atoms in a water molecule explains many of water’s chemical properties. In each water molecule, the nucleus of the oxygen atom (with 8 positively charged protons) attracts electrons much more strongly than do the hydrogen nuclei (with only one positively charged proton). This results in a negative electrical charge near the oxygen atom (due to the "pull" of the negatively charged electrons toward the oxygen nucleus) and a positive electrical charge near the hydrogen atoms. A difference in electrical charge between different parts of a molecule is called polarity. A polar molecule is a molecule in which part of the molecule is positively charged and part of the molecule is negatively charged.
•Hydrogen Bonding-
Opposite electrical charges attract one another. Therefore, the positive part of one water molecule is attracted to the negative parts of other water molecules. Because of this attraction, bonds form between hydrogen and oxygen atoms of adjacent water molecules. This type of bond always involves a hydrogen atom, so it is called a hydrogen bond. Hydrogen bonds are bonds between molecules, and they are not as strong as bonds within molecules. Nonetheless, they help hold water molecules together.
•Sticky, Wet Water-
Water has some unusual properties due to its hydrogen bonds. One property is cohesion, the tendency for water molecules to stick together. The cohesive forces between water molecules are responsible for the phenomenon known as surface tension. The molecules at the surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface. For example, if you drop a tiny amount of water onto a very smooth surface, the water molecules will stick together and form a droplet, rather than spread out over the surface. The same thing happens when water slowly drips from a leaky faucet. The water doesn't fall from the faucet as individual water molecules but as droplets of water.
•Density of Ice and Water-
The melting point of water is 0°C. Below this temperature, water is a solid (ice). Unlike most chemical substances, water in a solid state has a lower density than water in a liquid state. This is because water expands when it freezes. Again, hydrogen bonding is the reason. Hydrogen bonds cause water molecules to line up less efficiently in ice than in liquid water. As a result, water molecules are spaced farther apart in ice, giving ice a lower density than liquid water. A substance with lower density floats on a substance with higher density. This explains why ice floats on liquid water, whereas many other solids sink to the bottom of liquid water.In a large body of water, such as a lake or the ocean, the water with the greatest density always sinks to the bottom. Water is most dense at about 4°C. As a result, the water at the bottom of a lake or the ocean usually has temperature of about 4°C. In climates with cold winters, this layer of 4°C water insulates the bottom of a lake from freezing temperatures. Lake organisms such as fish can survive the winter by staying in this cold, but unfrozen, water at the bottom of the lake.

Notice that the bond strength for lithium bonded with any of the anions is larger than the bond strength of potassium bonded with any of
the same anions. Propose a scientifically sound explanation for this.
Select one:
O a. Lithium comes before sodium or potassium alphabetically, so its bond will be stronger.
O b. Sodium and potassium are essential for human metabolism, so they should not bond as strongly with anions.
Oc. Lithium is the smallest cation, so bond length is shorter creating a tighter bond.
Od Lithium is the only cation with a +1 charge.
Check
The bond strength for lithium bonded with any of the anions is larger than the bond strength of potassium bonded with any of the same anions because lithium is the smallest cation, so bond length is shorter creating a tighter bond.
The strength of an ionic bond ultimately depends on the size of the ions. The smaller the ions the stronger the bond and the higher the lattice energy. Such compounds having a high lattice energy tend to deviate from the normal behavior of ionic crystals due to significant covalent contribution.
Lithium is the smallest cation in group 1. Hence, the bond strength for lithium bonded with any of the anions is larger than the bond strength of potassium bonded with any of the same anions because lithium is the smallest cation, so bond length is shorter creating a tighter bond.

What causes the electrons to move and form static electricty?
contact between two substances
friction
Moist air
Answer:
Static electricity is the result of an imbalance between negative and positive charges in an object. ... When two materials are in contact, electrons may move from one material to the other, which leaves an excess of positive charge on one material, and an equal negative charge on the other.
Answer: 1) Contact between two substances.
Explanation:
#1 When fuel is running through pipes, there is a lot of contact between the fuel and the pipe.
To avoid explosions, fuel trucks have a metal chain that hangs to the ground to discharge the static. When a jet plane is being fueled up, it is first connected to a metal spike that is sunk down into the ground.#2 Before, people thought that Static at first was caused by friction, meaning the rubbing (of an object, pause) had something to do with static.
People later on noticed that fuel trucks and jet planes were being filled with fuel.A large static charge built up from the fuel running through the pipes when fuel trucks and jet planes were being filled with fuel.End note: Your welcome. My apologies if I was late, I was trying to find the answer to this question, too, until I got all this information while taking notes from my Physical Science lesson.
Will tin reduce iron?
Answer: The iron equilibrium is the more positive, and so will go in the forward direction. The tin equilibrium is less positive (more negative), and will be driven backwards. So the tin(II) ions will reduce iron(III) ions to iron(II) ions. In the process, of course, the tin(II) ions will be oxidised to tin(IV) ions.

You have 505 mL of a 0.160 M HCl solution and you want to dilute it to exactly 0.100 M. How much water should you add
This problem is providing information about the volume and concentration of HCl as 505 mL and 0.160 M respectively, and it is asking for the water that have to be added to prepare a 0.100-M solution.
In such a way, we work over the assumption of constant moles in dilution processes, so that we are able to write:
[tex]M_1V_1=M_2V_2[/tex]
Which relates de volume and concentration at the beginning and end of the experiment. This means we can solve for the resulting volume of the solution as a first calculation:
[tex]V_2=\frac{M_1V_1}{M_2}\\\\V_2=\frac{0.160M*505mL}{0.100M}=808mL[/tex]
Hence, the following amount of water must be added:

Explanation:
We are asked to find the volume of 0.25 moles of oxygen gas.
At standard temperature and pressure or STP, one mole of any gas has a volume of 22.4 liters.
We want to convert 0.25 moles of oxygen gas or O₂ to liters. We will use dimensional analysis, so we must set up a conversion factor.
[tex]\frac {22.4 \ L \ O_2}{1 \ mol \ O_2}[/tex]
We are converting 0.25 moles of oxygen gas, so we multiply the conversion factor by this value.
[tex]0.25 \ mol \ O_2 *\frac {22.4 \ L \ O_2}{1 \ mol \ O_2}[/tex]
The units of moles of oxygen gas cancel.
[tex]0.25 *\frac {22.4 \ L \ O_2}{1 }}[/tex]
