Write an equation that represents the second ionization energy of nickel.
Answers
The equation that represents the second ionization energy of nickel is [tex]\rm Ni+ (g) \rightarrow Ni^2^+ (g) + e-.[/tex]
What is the second ionization energy?The energy needed to free the outermost, or least bound, an electron from an element's 1+ ion is known as the second ionization energy.
The second ionization energy of an element is usually greater than the first because positive charge more strongly attracts electrons than negative charge.
The chemical equation is the representation of the chemical reaction. The left side of the substance and compound is the reactant and the right side of the substance is the product.
Nickel is a chemical element. Its chemical symbol is Ni. Its atomic number is 28. It's a silvery luster metal.
Therefore, the equation is [tex]\rm Ni+ (g) \rightarrow Ni^2^+ (g) + e-.[/tex]

How is atmospheric oxygen linked to the carbon cycle?.
Answers
Atmospheric oxygen is closely linked to the carbon cycle through the process of photosynthesis and respiration.
During photosynthesis, plants and other photosynthetic organisms use carbon dioxide (CO₂) from the atmosphere, along with sunlight and water, to produce glucose (C₆H₁₂O₆) and oxygen (O₂) as a byproduct. This process removes carbon dioxide from the atmosphere and releases oxygen, contributing to the oxygen content in the atmosphere.
On the other hand, during respiration, organisms, including plants, animals, and microorganisms, use oxygen from the atmosphere to break down glucose and release carbon dioxide as a waste product. This process releases carbon dioxide into the atmosphere and consumes oxygen.
Hence, the atmospheric oxygen is linked to the carbon cycle.

is the ability of a substance to reflect light a chemical property
Answers
Answer:
If it reflects all light, it looks white. Color can help identify a material and, while it is a physical property, it can be used together with chemical experiments when the experiments produce a known material with a specific color.
Explanation:
The ability to reflect light is the inherent and fundamental property of that substance.
What type of object reflects light?When waves of light (and other electromagnetic radiation) come into contact with a surface or other boundary that does not absorb the radiation's energy, the waves bounce off the surface and back into space. The light wave that is coming in is known as the incident wave, and the wave that is being reflected off of the surface is known as the reflected wave. As seen for the operation of a flashlight beam on a smooth, flat mirror, visible white light that is focused onto the surface of a mirror at an angle (incident) is reflected back into space by the mirror surface at another angle (reflected) that is equal to the incident angle.For visible light and all other wavelengths of the electromagnetic radiation spectrum, the angle of incidence is the same as the angle of reflection. This idea is frequently referred to as the Law of Reflection. It is significant to notice that because the light is not "bent" or refracted and is being reflected at all wavelengths equally, it is not broken up into its individual hues. Practically all surfaces will reflect light to some extent, particularly smooth surfaces, like a glass mirror or polished metal, work best for doing so.To learn more about reflective objects, refer to

Fresh water is always (A)_____________________ than salt water so it (B)____________________ the salt water.
Question 4 options:
(a) less dense (b) rises above
(a) more dense (b) sinks below
Answers
Answer:
3. (a) more dense (b) sinks to the bottom
4. (a) less dense (b) rises above
Explanation:
To understand this, first you need to know what density is. Density is the quantity of mass per unit. If something is dense it has many molecules per unit of volume. If something is not so dense it has few molecules per unit of volume.
Cold water is close to becoming ice. In ice (solid), the molecules are compacted very tightly, therefore there are more molecules per unit of volume. This means that ice is very dense. In cold water, the molecules are close but not as close as in ice. This means that cold water is dense.
Hot water is close to becoming a water vapour. In water vapour (gas) the molecules are spaced very far apart and move around freely. They have lots of energy so they vibrate and move around a lot. There are less molecules per unit of volume in water vapour. This means that water vapour is not dense. In hot water, the molecules are not so far apart as the molecules in water vapour. This means that hot water is not so dense. But it is still considerably denser.
Salt water has two different types of molecules. The salt molecules like to cluster around the water molecules very close together. This makes salt water more dense than just plain water (freshwater).

explain how both hydrogen and carbon have achieved stability by bonding with each other to form methane
Answers
A carbon iota can bond with four other iotas and is just like the four-hole wheel, whereas an oxygen iota, which can bond only to two, is just like the two-hole wheel.
Each element tries to achieve stability by forming a noble gas configuration (2 or 8 valence electrons)
Carbon has 4 valence electrons, achieving stability requires 4 more electrons
Hydrogen has 1 valence electron, achieving stability requires 1 more electron
Carbon and hydrogen bond covalently by sharing their electrons so that they become stable (carbon binds 4 hydrogens) to form CH₄ (methane)

Answers
This problem is asking for the for pH when a solution of potassium hydroxide is diluted to the double of its initial volume. Thus, the answer turns out to be 11.0.
pH calculationsIn chemistry, pH calculations are performed based on the following equation relating the pH and the concentration of hydrogen ions in the solution:
[tex]pH=-log([H^+])[/tex]
However, since this problem involves a strong base, KOH as potassium hydroxide, one must calculate the pOH instead, and then convert it to pH with the following equations:
[tex]pOH=-log([OH^-])\\\\pH=14-pOH[/tex]
In addition, due to the fact it is diluted from 10. mL to 20. mL (with the 10. mL of added distilled water), one needs to use the dilution equation in order to calculate the correct concentration of KOH:
[tex]M_1V_1=M_2V_2\\\\M_2=\frac{M_1V_1}{V_2} \\\\M_2=\frac{0.002M*10.mL}{20.mL}\\ \\M_2=0.001M[/tex]
Hence, the pOH turns out to be:
[tex]pOH=-log(0.001)=3.0[/tex]
And thereby the pH:
[tex]pH=14-3.0\\\\pH=11.0[/tex]
