what does a large positive standard cell potential imply about the spontenty of the redox reaction occuring in teh cell
Answer : E cell standard is the potential difference between the two electrodes under standard conditions. Overall tendency for the redox reaction to occur spontaneously. A large positive E cell means the reaction is more spontaneous, and a negative E cell indicates a non spontaneous reaction.

What is required for two atoms to share electrons equally in a chemical bend?
Answer: Nonpolar Covalent Bond
Explanation: A Nonpolar Covalent Bond is created when atoms share their electrons equally. This usually occurs when two atoms have similar or the same electron affinity. The closer the values of their electron affinity, the stronger the attraction. This occurs in gas molecules; also known as diatomic elements.

Answer: Six months or three years
Explanation: Frozen meats, poultry, and fish can last in the freezer for up to six months and when they are vacuum sealed, frozen meats can stay fresh and free from freezer burn for up to 3 years.
Which statement describes the motion of the ice particles in the ice/water bath between minutes 5 and 20?
Choose the correct answer.
Particle motion stays the same because temperature does not change.
Particle motion stays the same because the ice is not completely melted yet.
Particle motion increases because thermal energy is being transferred to the ice.
Particle motion decreases because thermal energy is being transferred away from the ice.
Explanation:
The ice cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the ice particles gather heat energy from the warmer air. Therefore the ice particles have enough energy to break apart (melt)into smaller particle arrangements.
Vanadium crystallizes in a body-centered cubic lattice, and the length of the edge of a unit cell is 305 pm. What is the density of V
Answer:
5.96 g/cm^3
Explanation:
Corner atom = 1/8
Atoms in center = 1
Atoms in face of the cube= 1/2
Molar mass of V = 50.94 g/mol (from period table)
1 mole = 6.02x10^23
In BCC unit cell:
(8 x 1/8)+ 1=2 per 1 unit cell
Mass: 2(50.94g)/6.02x10^23 = 1.69x10^-22 g/unit cell
305pm=(305x10^-12m÷10^-2m) x (1mL÷1cm^3)
= 2.837 x 10^-23 mL
1pm=10^-12m
1cm=10^-2m
1mL=1cm^3
density=mass/volume
density of V = 1.69x10^-22g÷2.837x10^-23mL
=5.957g/mL
=5.96g/cm^3

crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.
Sugar and salt are examples of products where crystallization does not only serve as separation/purification technique, but where it is also responsible for getting crystals with the right size (and shape) for further application of the products.
- BRAINLIEST answerer
Answer:
Crystallization is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

Analysis of a molecule of DNA showed that cytosine accounted for 42 per cent of the
content of the nitrogenous bases. Calculate the percentage of bases in the molecule
which would be thymine. Show your working.
8%
Explanation:
In a DNA molecule the no. of Adenine bases equal to that of Thymine bases
The no. of Cytosine bases equal to that of Guamine bases.
If we take no. of Thymine bases as x and no. of Cytosine bases as y,
Adenine + Thymine + Cytosine + Guamine = 100
x + x + y+y = 100
2( x+y) = 100
x+y = 50
y=42
therefore x= 50-42 = 8%

The half-life of Palladium-100 is 4 days. After 16 days a sample of Palladium-100 has been reduced to a mass of 6 mg. What was the initial mass (in mg) of the sample
Answer:
96mg
Explanation:
Since the half-life of Palladium-100 is 4 days and the sample has been reduced after 16 days, that means the sample has undergone four half-lives. To find the intial mass, just work backwards:
6 x 2= 1212 x 2= 2424 x 2= 48 48 x 2= 96As you see, I've worked backwards from the four half-lives. So the initial mass after 16 days is 96 mg.

Given the Latin meaning of the cogito, we can confirm that it is roughly translated and summarized by the phrase "I think, therefore I am".
Cogito, ergo sum or "The Cogito" is an extremely popular, well-known philosophical phrase credited to Rene Descartes. This Latin phrase is roughly translated as "I think, therefore I am", which appeared originally in "The Principles of Philosophy", and was later translated to a variety of languages in an attempt to reach a wider public, most notably into Latin.

How could the student obtain zinc chloride solution from the reaction mixture when all the hydrochloric acid has reacted?
Answer:
zinc oxide is only sparingly soluble in water so best option is to add zinc oxide to diluted hydrocrolic acid
When all the hydrochloric acid (HCl) has reacted, the student can obtain zinc chloride (ZnCl) solution from the reaction mixture by adding ZnO to diluted HCl.
What is a mixture?
A mixture simply refers to a combination of two (2) or more substances or chemical compounds that are present in varied proportion, and they can be visibly seen with na-ked eyes.
In this scenario, the student can obtain zinc chloride (ZnCl) solution from the reaction mixture when all the hydrochloric acid (HCl) has reacted by adding zinc oxide (ZnO) to diluted hydrochloric acid (HCl) because it's sparingly soluble in water.

A sample of gas has a volume of 3.50 L and a pressure of
125 mm Hg. What will the new pressure be when the volume
is decreased to 2.75 L? The temperature stays the same.
Answer:
159.09 mmHgExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
[tex]P_2 = \frac{125\times3.50 }{2.75} = \frac{437.5}{2.75} \\ = 159.090909...[/tex]
We have the final answer as
159.09 mmHgHope this helps you

find 5 points for each section
Answer:
Differences
• Space is everything in the universe beyond the top of Earth's atmosphere - The moon, Stars, Milky way, etc.
• In space, no one can hear you scream. This is because there is no air in space, i.e, it's vacuum.
• Earth is a planet on solar system. It is the only planet where life exists!!
• Earth is also called "blue sky" cause it has 75% water.
Similarities
•They need oxygen for survival: Man, animals in earth and space need oxygen for survival.
•Water is also need to stay alive.
•Food is very paramount to both man, animal s and organisms.
•Shelter, we all ned a place to lay our head in other to be safe.
•Air everywhere in the atmosphere.
•Water, air, food and shelter are available on earth but their availability differs in space.
•Astronaut need to bring everything one need in space with him or her from Earth. They often recycle the things they bring.

What are aliens?The living things that are believed to be exists in out of earth is called aliens. Some studies shows that there is a possibility to find exotic species living in space.
The study which deals with aliens is called exo-biology. The atmosphere thus, the presence gases, temperature, pressure, etc. will be different for space from that in the earth.
Hence, aliens may need not the presence of oxygen for living as well as the atmospheric conditions that maintains living in earth will not be there in space.
However, any living irrespective of earth or space need water and some kind of food to survive. Thus the presence of water in some planets opens the way to study the presence of livings there.
