Answer:
Explanation:
Procrastination is a plague to which we are all susceptible. Essentially, procrastination is the avoidance of work or necessary tasks by focusing on more satisfying activities. It’s easy to chalk procrastination up to a lack of self-motivation, lazy habits or incompetence. But in reality, procrastination is chemical; there’s a science to why we prefer relaxing activities to the required.
Procrastination boils down to a battle between the limbic system and the prefrontal cortex. The limbic system is a set of brain structures containing the pleasure center, while the prefrontal cortex controls planning and decision making. The prefrontal cortex is less developed and thus weaker, so often times the limbic system wins out, leading to procrastination.

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.

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 the reaction represented by the equation 2Al2O3 → 4A1 + 302, calculate the
theoretical amount in grams of oxygen, O2 produced if 11.84 grams Al2O3
decomposes?
Answer:
3.78 gm O2
Explanation:
In the reaction represented by the equation 2Al2O3 → 4A1 + 302, calculate the theoretical amount in grams of oxygen, O2 produced if 11.84 grams Al2O3 decomposes?
for every 2 moles of Al2O3, 3 mole of 02 are produced
molecular weight of Al2O3 =(2X27) + (3X32) =54+96= 150
11.84 gm Al2O3 = 11.84/150 moles =0.0789 moles
This will produce 3/2 X 0.0789 moles of O2 = 0.118 moles O2
mol wt of O2 is 32
0.118 moles weighs 0.118X32 = 3.78 gm O2

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).

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.

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.

Assuming non-ideal behavior, a 2.0 mol sample of CO₂ in a 7.30 L container at 200.0 K has a pressure of 4.50 atm. If a = 3.59 L²・atm/mol² and b = 0.0427 L/mol for CO₂, according to the van der Waals equation what is the difference in pressure (in atm) between ideal and nonideal conditions for CO₂?
The difference between the pressure in ideal and nonideal conditions for the CO₂ gas is 0.22 atm.
The given parameters;
number of moles of the gas, n = 2 molvolume of the gas, V = 7.3 Ltemperature of the gas, T = 200 Kpressure of the ideal gas, P₁ = 4.5 atmconstant, a = 3.59 L²atm/mol²constant, b = 0.0427 L/molThe van der Waals equation is calculated as follows;
[tex](P + \frac{an^2}{V^2} )(V-nb) = nRT\\\\P = \frac{nRT}{V-nb} - \frac{an^2}{V^2} \\\\P = \frac{2\times 0.082057 \times 200}{7.3 \ -\ 2\times 0.0427} - \frac{3.59\times 2^2}{7.3^2} \\\\P = 4.281 \ atm[/tex]
The difference between the pressure in ideal and nonideal conditions for the CO₂ gas is calculated as;
[tex]\Delta P = P_{ideal} - P_{nonideal}\\\\\Delta P = 4.5 \ atm \ - \ 4.281 \ atm\\\\\Delta P = 0.22 \ atm[/tex]
Thus, the difference between the pressure in ideal and nonideal conditions for the CO₂ gas is 0.22 atm.
