Answer:
When the following redox equation is balanced with smallest whole number coefficients, the coefficient for the iodide ion will be __6__.
Explanation:
From the redox equation, we can see that NO₃⁻ is reduced to NO (from oxidation state +5 to +2), whereas I⁻ is oxidized to I₂ (from oxidation state -1 to 0). The half reactions are balanced with H⁺ (acidic solution), as follows:
Reduction : 2 x (NO₃⁻(aq) + 3 e- + 4 H⁺ → NO(g) + 2 H₂O)
Oxidation : 3 x (2 I⁻(aq) → I₂(s) + 2 e-)
----------------------------------------------------------------------
Total equation: 6 I⁻(aq) + 2 NO₃⁻(aq)+ 8 H⁺ → 3 I₂(s) + 2 NO(g) + 4 H₂O
That is the redox equation with the smallest whole number coefficients.
Accordin to this, the coefficient for the iodide ion (I⁻) is: 6.
What Happens During Fermentation?
Answer:
Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol.
Sometimes bacteria perform fermentation, converting carbohydrates into lactic acid...

Describe the nitrogen cycle
The nitrogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms. The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.

What do you think the ideal pH of a swimming pool should be? Explain.
Answer:
Explanation:
The pH scale goes from 0 to 14, where pH 7 is neutral. If the pH is above 7, the water is basic; if it is below 7 the water is acid. The optimum pH for pool water is 7.4, since this is the same as the pH in human eyes and mucous membranes. A pH of 7.4 also gives good chlorine disinfection.

What led to the increase in steel consumption seen on the graph?
The cause that led to the increase in steel consumption seen in the graph is the increase in population.
In the graph, you can see the relationship between the millions of people and steel consumption and the centuries. The graph shows that population growth between 1700 and 1900 was minimal because it did not exceed 100 million people.
From 1900 onwards the population began to grow from 100 million to 600 million.
On the other hand, steel began to be exploited in the mid-1800s and until 1900 it had not exceeded 100 million tons. After 1900 it increased rapidly to 250 million tons and by the year 2000, it had already exceeded 700 tons.
According to the above, it can be inferred that the growth of steel consumption was influenced by the growth of the population.

1. Describe What happens to a hydrogen
atom in an acid when the acid is dissolved
in water?
Answer:
The H+ atoms will become neutralized by the OH- ions in the water. This is due to the fact that when acids are dissovled in water, they give H+ ions (Hydrogen ions). When the H+ ions from the acid join with the OH- ions in the base (water), they'll become neutralized and form H₂O (Water molecule).
an inert gas that has a bigger atomic radius than element E(in number 2)
Explanation:
This is due to the reason that in case of inert gases, the outer shell is complete and it has hence maximum electronic repulsion. Moreover in case of inert gases, the atomic size is expressed in terms of Vanderwaal’s radius because, noble gases do not form covalent bonds while other form covalent bonds and hence their atomic radii is expressed in covalent radius. Generally atomic size decreases while moving from left to right in the periodic table. But in the case of noble gases, they have comparatively higher atomic size than corresponding halogens because of the reason that vanderwaal’s radii (present in noble gases) is much larger than ionic and covalent radii (present in other elements). Thus as, Vanderwaal’s radius is greater than covalent radius, the atomic size of noble gases is larger than other elements of same period.

a ionic bond is the strongest of the three major bonds. due to its strong lattice structure. a metallic bond is the weakest of the three due to the sea of electrons. what determines the strength of metallic bonds?
The strength of metallic bonds is dependent on the protons, delocalized electrons and ions.
The strength of a metallic bond is dependent on:
The number of protons: The higher the number of protons the more stronger the bond.Delocalized electrons: The higher the number of delocalized electrons the more the stronger the bond.Ion: The smaller the size of the ion, the stronger the bond.The strength of metallic bonds is dependent on the protons, delocalized electrons and ions.

In three to five sentences, predict the bonding activity of magnesium (mg) and chlorine (Cl). Why do you think they would bond that way?
Answer:
Magnesium and Chlorine have a great difference in there electronegativies. Due to this, they will form an ionic bond. Magnesium has 2 valence electrons and chlorine has 7. Therefore, two magnesium atoms will give one electron to one chorine atom, making the chlorine atom stable.
The bonding activity of magnesium (mg) and chlorine (Cl) will lead to ionic bonding.
It should be noted that Magnesium and Chlorine have a great difference in their electronegative and this will lead to the formation of an ionic bond.
Magnesium has 2 valence electrons while chlorine has 7 valence electrons. In such a case, the two magnesium atoms will give one electron to one chlorine atom. This is vital for making the chlorine atom stable.
In conclusion, an ionic bond will be formed between them.

Answer: Holmium-165 = Er-165 + electron
Explanation:
Beta decay is the decay of a neutron into a proton and electron. This will increase the number of protons in the Holmium nucleus by one, making it Er, Erbium, with the same atomic mass.
Holmium-165 = Er-165 + electron
The mass is essentially the same, as the proton is assigned the same mass as the neutron it came from.
