Explanation:
9.7-8.65=1.05
But significant figure rules mean use only the smallest number of significant figures. 9.7 has 2 and 8.65 has 3, so your answer can only have 2 sig figs.
So round 1.05 to 2 figures and you get 1.1
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.

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).

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 character of the actual elements (aluminum, silicon, oxygen) present in alumina and silica cause the stationary phase to be very polar?.
Answer:
aluminum and silicon and the electronegative character of the oxygen.
Explanation:
.
The electronegative character of alumina and silica and the electropositive character of oxygen causes the stationary phase to be very polar.
What are electronegative?Electronegativity is defined as the tendency for an atom of a given chemical element to attract shared electrons or electron density when forming a chemical bond.
Non metals are usually an electronegative elements.
Electro positivity is defined as the tendency for an element to lose the electron to form a positive ions.
It is also known as metallic character. Metals are usually an electropositive elements.
Thus, the electronegative character of alumina and silica and the electropositive character of oxygen causes the stationary phase to be very polar.

Why is a crystal of Strontium chloride described as an extended structure?
Answer:
Explanation:
Chloride is described as an extended structure because its atoms are arranged following an endless repeating pattern and are of distinct ratio
Crystals and polymers mostly form extended structures as seen in the formation of sodium chloride whereby the ions in the compound are arranged following a repeating pattern. ( i.e. has a giant ionic structure ).
Chloride is a considered an extended structure because in sodium chloride it forms an unending repeated pattern of ions which makes it a perfect example of an extended structure.
Hence we can conclude that Chloride can be described as an extended structure because its atoms are arranged following a repeating pattern and are of distinct ratio.
Crystal of Strontium chloride is described as an extended structure because it is arranged in a repeating pattern.
Crystals form extended structures means a group of atoms or molecules in a distinct ratio that are present in a repeating pattern. Crystals are made up of atoms of one element that grouped together or can be made up of molecules grouped together.
Due to repeating pattern and constant ratio of strontium chloride then it is considered as repeating structure so we can conclude that Crystal of Strontium chloride is considered as an extended structure due to its arrangement in a repeating pattern.

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.

hey! needing some help with this
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.

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.

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.
