The highest pressure ever produced in a laboratory setting was about 2.0 x 10 6 atm. If we have a
1.0 x 10 -5 liter sample of a gas at that pressure, then release the pressure until it is equal to 0.275 atm,
what would the new volume of that gas be?

Answers

Answer:

Volume = 72.7272

Explanation:

if only pressure and volume change, then we can do some simple math to find the answer.

2 x 10 ^ 6 times 1 x 10 ^-5 = 20

pressure and volume must equal 20

20 = 0.275 x volume

20 / 0.275 = new volume

I don't remember significant digits but your volume is 72.72727272 just repeated

If we have a 1.0 x 10 -5 liter sample of a gas at that pressure, then release the pressure until it is equal to 0.275 atm, the new volume will be 72.7272

What is Volume?

Volume is the space occupied by a three-dimensional object.

By the Boyle's law

[tex]\rm P_1V_2= P_1V_2[/tex]

P1 (initial pressure) = [tex]2.0 \times10^6 atm[/tex]

V1 (initial volume) = [tex]1.0 \times10^-5 L[/tex]

P2 (final pressure) = 0.275 atm

V2 (final volume) = ? (in L)

Putting the values in the equation

[tex]\rm 2.0 \times10^6 atm \times 1.0 \times10^-5 L = 0.275 atm \times V_2\\\\V_2 = \dfrac{20}{0.275} = 72.72 L[/tex]

Thus, the volume is 72.72 L.

What would the [OH-] of a solution that has a pOH of 2.7 be?

Answers

Answer:

The [OH⁻] of a solution that has a pOH of 2.7 will be 2*10⁻³

Explanation:

The pOH (or potential OH) is a measure of the basicity or alkalinity of a solution.

pOH indicates the concentration of hydroxyl ions [OH-] present in a solution. In this way, pOH is defined as the negative logarithm of the activity of hydroxide ions, that is, the concentration of OH- ions:

pOH= -log [OH⁻]

In this case, pOH has a value of 2.7. Replacing:

2.7= -log [OH⁻]

and solving:

[OH⁻]=10⁻² ⁷

you get:

[OH⁻]≅ 2*10⁻³

The [OH⁻] of a solution that has a pOH of 2.7 will be 2*10⁻³

write in your own words

Answers

Answer:

Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic

What is an element ?

A chemical element is a species of atoms, including the pure substance made entirely of that species, that have a specific number of protons in their nuclei. Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules.

They can be identified by their particular atomic number. The periodic table groups the elements according to their atomic number and draws attention to those with related qualities.

The most vital ingredient for life is carbon. Life as we know it would not exist without this element. You'll see that carbon is the main component of the chemicals required for life.

Thus, The element having electronic configuration 1s₂, 2s₂, 2p₆, 3s₂, 3p₆, 4s₂, 3d₁₀, 4p₆, 5s₁ is rubidium .

How many grams of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)?

Answers

Answer:

[tex]55.1657[/tex] grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)

Explanation:

The molecular weight of acetylene is  26.04 g/mol

Molecular weight of carbon is equal to 12.011 g/mol

Two carbon atom produces one acetylene molecule.

Thus, 2 * 12.011 g/mol of carbon is used to produce  26.04 g/mol of acetylene,

If you tested two samples of a particular pure substance, what would you find?

Answers

Answer:

The properties of a pure substance can be used to determine whether a sample is a pure substance or mixture because the characteristic properties of matter can be used to identify a sample. The result is a mixture called a composite.

Explanation:

Pure substances contains their own molecules only and not any  impurity. Thus, when we tested it  only shows the properties of its own.

What are pure substances?

Pure substances are substances containing its pure composition without any impurities. For example water, fruits, acids etc. are pure substances and they does not have a combination other substances.

Mixtures are the combination of two or more pure substances, and the can be heterogenous or homogenous. Whereas, pure substances homogenous only thus forming only one phase.

When we tested mixtures qualitatively, they shows the properties of each  individual components in it. Whereas, pure substances give inly its own characteristics.

Check all that apply.

A. Elements in a group have the same number of protons.
B. Elements in a group have the same number of electron shells.
C. Elements in a group have similar properties.
D. Elements in a group have the same number of neutrons.

Answers

Answer: it’s only c

Explanation:

The correct statement regarding groups on the periodic table is statement C which is elements in a group have similar properties.

A. Elements in a group may have different numbers of protons, as the group represents elements with similar valence electron configurations, but the number of protons in the nucleus can vary.

B. Elements in a group do not have the same number of electron shells. Elements within the same group have similar outer electron configurations, which determine their chemical properties. The number of electron shells increases as you go down the group.

C. Elements in a group have similar properties. Elements within the same group share similar chemical behavior due to their similar outer electron configurations. This similarity leads to recurring patterns in their physical and chemical properties.

D. Elements in a group may have different numbers of neutrons. The number of neutrons can vary within a group as different isotopes of an element can exist, which have the same number of protons but different numbers of neutrons.

Therefore, the correct option is option c
