A 2.00 L pocket of air at sea level has a pressure of 99.9 atm. What is the
pressure if the pocket of air rises and expands to 8.0 L? *
0.04 atm
O
400 atm
25 atm
52 atm
Answer:
The answer is 25 atmExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
From the question we have
[tex]P_2 = \frac{2 \times 99.9}{8} = \frac{199.8}{8} \\ = 24.975[/tex]
We have the final answer as
25 atmHope this helps you

Most plastics are made from oil or natural gas. One step in making plastics from these resources is called cracking. Cracking is a process that breaks down bigger molecules into smaller ones. In one cracking reaction, ethane breaks down to become ethylene and hydrogen. During this process, thermal energy is absorbed from the surroundings and converted to chemical energy.

a cube has a length of 1.02 cm and a mass of .001012 kg what is its density
Answer:
d = 9.5× 10⁻⁴ Kg/cm³
Explanation:
Given data:
Length of cube = 1.02 cm
Mass of cube = 0.001012 Kg
Density of cube = ?
Solution:
The length , height and width of cube is always same. Thus the volume of cube is,
Volume = length × height× width
Volume = 1.02 cm × 1.02 cm × 1.02 cm
Volume = 1.06 cm³
Density of cube:
d = 0.001012 Kg /1.06 cm³
d = 9.5× 10⁻⁴ Kg/cm³

Chemical and physical element properties are determined by their valence electrons. How do you describe metals with only one valence
electron?
A .highly reactive
B. poor conductors of electricity
C. reactive with other metals
D. likely to gain more electrons
Answer:
B
Explanation:
Chemical and physical element properties are determined by their valence electrons metals with only one valence electron are poor conductors of electricity. Option B is correct.
What are valance electrons?Valence electrons are the electrons present at the valance shell or orbit of the atom and always take part in the chemical reaction or reaction with other metals and can conduct electricity.
If the atom contains only one valance electron in the outermost shell or valance shell then it cannot conduct the electricity properly due to the fewer number of electrons.
Therefore, Option B is correct. Chemical and physical element properties are determined by their valence electrons metals with only one valence electron are poor conductors of electricity.

The reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms. In order to follow the conservation of matter, the products of the chemical equation will have
Answer:
The same amount of atoms (3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms).
Explanation:
According to the law of conservation of mass, when a chemical reaction takes place there is no synthesis or degradation of matter, that is, matter can be neither created nor destroyed. It can only be transformed.
Therefore, in a chemical reaction the atoms are conserved. That means that the elements that in definite proportions are forming a compound, will reorganize to form new compounds, and the amount and type of atoms of the products will be the same as the reactants.
In summary, if the reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms, the products of the chemical equation will have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms as well.

Learn how factors, such as exposure to the atmosphere, the composition of rock and climate affect the rate of weathering. Weathering is the mechanical or chemical process by which rocks are broken down. The weathering that happens to rocks can be understood by relating it to the digestion of a chocolate chip cookie
One of the factors that affects the rate of weathering is exposure to the atmosphere. ... Another factor that affects the rate of weathering is the composition of rock. Rocks are composed of minerals, which are solid substances found within rocks that have their own distinct chemical composition.

If a compound begins with a metal, it most likely is a _______ compound
metallic
molecular
covalent
ionic
Answer:
A
Explanation:
If a compound begins with metal, it is most likely to be a metallic compound. Thus, option A is correct.
The metallic compound has been formed when the metal has been bonded with a metal or more than 1 metal by the ionic or covalent interaction.
The ionic interactions result in between the metal and non-metal or between two metals, and the covalent interactions have been found in the nonmetals.
The molecular compound has been the one that has been formed a molecule. All the compounds are molecular compounds.
Thus, if it starts with metal, it has been most likely to form a metallic compound. Thus, option A is correct.
