General gas lawAccording to the general gas law, the ratio of the product of the pressure and volume to its temperature is constant.
The general gas law is summarily expressed as the following equation:
[tex]p_1v_1/t_1[/tex] = [tex]p_2v_2/t_2[/tex]. where:
[tex]p_1[/tex] = initial pressure of a gas
[tex]v_1[/tex] = initial volume of the gas
[tex]t_1[/tex] = initial temperature of the gas
[tex]p_2[/tex] = final pressure of the gas
[tex]v_2[/tex] = final volume of the gas
[tex]t_2[/tex] = final temperature of the gas
In this case:
[tex]p_1[/tex] = standard pressure = 1 atm
[tex]v_1[/tex] = 73 mL or 0.073 L
[tex]t_1[/tex] = standard temperature = 273 K
[tex]p_2[/tex] = ?
[tex]v_2[/tex] = 4.53 L
[tex]t_2[/tex] = 80 + 273 = 353 K
[tex]p_2[/tex] = [tex]p_1v_1t_2/t_1v_2[/tex]
= 1x0.073x353/273x4.53
= 25.769/1236.69

If metals and non-metals make bonds and non-metals and non-metals make bonds, can metals and metals do the same? How?
Yes, metals and metals make bonds with one another forming a new substance.
Can metal and metal bond with one another?Metallic bonds occur between metal atoms whereas ionic bonds combine metals with non-metals. The metallic bonding joins metal atoms with each other. A sheet of aluminum foil and a copper wire are fused with the help of metallic bonding.
Metallic bonding is mostly non-polar because in alloys there is less difference among the electronegativities of the atoms that contribute to the bonding interaction of the two metals. Thus, metallic bonding is an extremely delocalized form of covalent bonding. Metals can make a bond with each other on macroscopic level as well as on a molecular level. The pieces of metal are held together with the help of metallic bonding.
So we can conclude that metals and metals do the same as metals and non-metals.

calculate the ph of a solution prepared by mixing 0.0750 mol of chloroacetic acid plus 0.0180 mol of sodium chloroacetate in 1.00 l of water.
When 0.0750 mol of chloroacetic acid and 0.0180 mol of sodium paients are combined with 1.00 l of water, the resulting solution has a pH of 2.373.
Chloroacetic is why?Stronger than acetic acid CH3-COOH is chloroacetic acid Cl-CH2-COOH. Cl is a group that removes electrons. By dispersing negatively charged by an inductive effect and stabilising the acetate anion, it makes acetic acid more acidic.
Chloroacetic acid is more, why?In chloroacetic acid, the Cl- ion has a -I effect that lowers the electron of the carboxylic group's O-H bond, whereas in acetic acid, the CH3 group has a +I impact that raises the O-H bond's electron density. Consequently, acetic acid is less acidic than chloroacetic acid.

Answer:
1. Acid - Red
2. Base - Yellow
3. Salt - Yellow if the reaction produces a base
Explanation:
In an acidic medium, methyl orange turns red, while in a basic medium, it turns yellow.
Sodium chloride solution produces sodium hydroxide, NaOH which is a strong base. Using methyl orange as an indicator gives a yellow colour solution for NaOH.
There are acidic, neutral, and basic salts. Sodium chloride (NaCl) produces a base therefore it would turn yellow as well but likely less distinct than the base.
Answer:
Hello methyl orange is a pH indicator that is commonly used.
If you drip methyl orange to an acidic liquid it will give you the color red.
If it turns yellow after you drip it then the liquid should be a base.
And it gives a yellowish color for neutral liquids

The new period of the earth would depend on its speed. It's impossible for a planet of earth's mass to orbit at the distance of Jupiter otherwise the earth and Jupiter would collide. according to the third law of Kepler the orbital period depends on the semimajor axis length but not on the mass of the planet. the mass of the earth is less than the mass of Jupiter.
The orbital period is proportional to r^(3/2) and does not depend on the satellite's mass. Any object at Jupiter's position will have the same orbital period regardless of mass. The correct answer is 11.9 yr. Option C.
As the Earth rotates on its axis creating day and night, it travels around the Sun in an elliptical orbit taking about 365 1/4 days to complete. The Earth's rotation axis is tilted with respect to the orbital plane. This creates seasons. The elliptical nature of the Earth's orbit is due to the first forces pushing the Earth away from the Sun's disk.
The momentum of this throw being greater the Earth's orbit would have been more elliptical or it might have been completely ejected from the solar system forever. The Earth's orbit defines a two-dimensional plane called the Ecliptic. It takes about 365 days for the earth to revolve around the sun. After years of analysis, Kepler found that Mars' orbit was likely elliptical, with the Sun at one of his focal points of the ellipse. This led Kepler to discover that all planets orbit the Sun in elliptical orbits and that the Sun is at one of his two focal points.

The density of WATER is 1gmL. Is the unlabeled clear liquid WATER? Why or why not
Answer:
Density is mass divided by volume (ρ=m/v), and water was used as the basis for establishing the metric unit of mass, which means a cubic centimetre (1cm3) of water weighs one gram (1g). So, 1g/1cm3 = 1 g/cm3, giving the water its easy-to-remember density.

What would a student need to know in order to figure out a formula for compound containing a group 16 nonmetal?.
"Will group 16 elements gain electrons to bond with group 2 in an XY format in periodic table would a student need to know in order to figure out a formula for compound containing a group 16 nonmetal.
From one side of the periodic table to the other, properties of elements within a period vary in a predictable manner. A horizontal row represents a period in the periodic table. The number of electron shells is the same for every atom in a row. Moving through a period causes elements to acquire electrons and protons and become less metallic. -Elements in the same period have the same number of electron shells.
As the atomic number rises, comparable features reoccur on a regular basis, which is reflected in this arrangement. From one side of the periodic table to the other, properties of elements within a blank shift in a predictable manner. those with comparable qualities are displayed in a column.
