Under which conditions does a real gas behave most like an ideal gas? A. At low temperatures and high pressures B. At low temperatures and low pressures C. At high temperatures and high pressures D. At high temperatures and low pressures
Answer: D. At high temperatures and low pressures
Explanation:
At low temperature and high pressure, the kinetic energy of gas molecules is negligible and molecules will have negligible forces of attraction. So real gases will behave least like an ideal gas under such conditions.
At high temperature and low pressure, energy due to intermolecular forces becomes less important in comparison to the kinetic energy of particles. The size of molecules also become less significant than the empty space between the gas molecules. So real gases behave in a similar manner to ideal gases at high temperature and low pressure.
What is a reflex? I am in k12 so I need the k12 answer please hurry VERY URGENT will give brainlist to first to answer.
Answer:
A reflex is an involuntary, or automatic, action that your body does in response to something — without you even having to think about it. You don't decide to kick your leg, it just kicks. There are many types of reflexes and every healthy person has them. In fact, we're born with most of them

Step 6: Measuring the Volume of Air Near 40°C
Temperature of gas: 40
COMPLETE
Height of the column of gas: 6.7
cm
Volume of gas (V =)
Temperature of gas: 303K
help me find out how to get the volume !!! pleaseeee
The volume using the cylinder formula : V=πr²h
Further explanationCharles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]
This experiment is an illustration of Charles's law, to determine the relationship between temperature and gas volume
If a certain amount of gas is heated, the volume will increase
So in this experiment, the temperature was changed as an independent variable and tube volume as a fixed variable
Because the tube is cylindrical, to find the volume using the cylinder formula
[tex]\tt V=\pi.r^2.h[/tex]
Meanwhile, to find the radius, you can use a caliper to measure the diameter of the tube and the result will be divided by 2
Answer:
1. Temp of gas 40C, Height of the column of gas 6.7
2. Temp of gas 313K, Volume of gas 0.84

How many valence electrons does an atom of oxygen have and what noble 1 point
gas will it be most like after forming a chemical bond? *
1)8 electrons and neon
2)2 electrons and fluorine
3)6 electrons and neon
4)6 electrons and argon
3)6 electrons and neon
Further explanationIn an atom there are levels of energy in the shell and sub shell
This energy level is expressed in the form of electron configurations.
The electron configuration Oxygen (atomic number = 8) :
1s²2s²2p⁴
Oxygen will try to achieve stability (according to the octet rule) by binding 2 electrons so that the 2p orbits are filled with 6 electrons, so that the configuration is stable like the noble gases Neon
₁₀Ne = 1s² 2s² 2p⁶
How many valence electrons are found in gallium? 3 5 7 8

why is the symbol [Ar] used in the electron configuration of potassium, and what does it represent?
Answer:
To denote a stable inner configuration and it represents argon
Explanation:
The symbol [Ar] used in the electron configuration of potassium represents the inner electronic configuration of the element.
This argon atom is stable octet with completely filled shells. Most noble gases are used to write the electronic configuration of other atoms. The inner atomic orbitals of elements are similar to those of nearby noble gases.
Ar is Argon with a configuration of 1s² 2s² 2p⁶ 3s² 3p⁶So, this configuration is stable and it the inner configuration of potassium excluding the outermost orbitals.Solvent: Will give brainliest

what is the reaction type of 3ZnS+ 2AlP = 1Zn3P2 + 1Al2S3 ?
Answer: double displacement
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The balanced chemical equation is:
[tex]3ZnS+2AlP\rightarrow Zn_3P_2+Al_2S_3[/tex]
Thus as ions get exchanged , it is double displacement reaction.
