Answer:
does not exist
perfectly obeys all gas laws
Explanation:
Ideal gases is a simplification of real gases that is made to study them more easily. Then a hypothetical or theoretical, that is to say, imaginary gas is considered ideal gases. Despite not representing a gas that really exists, the ideal gas is a tool to facilitate a large number of mathematical calculations
The ideal gas behavior is at low pressures and high temperatures.
The ideal gas equation is based condensing Boyle's law, Gay-Lussac's, Charles's and Avogadro's law:
P * V = n * R * T
where:
In this way an ideal gas perfectly obeys all gas laws.
b. Citrate lyase
c. Acetyl-CoA carboxylase
d. Malate dehydrogenase
The chemicals responsible for the red flame have been strontium, the green flame has been produced by barium, and sodium has been responsible for the yellow flame.
Aerial fireworks are produced by chemical change. The fireworks have been composed of gun powder and chemicals which provide color to the reaction. The gun powder has been composed of Potassium nitrate, copper, and sulfur. The combustion reaction takes place with gunpowder and heat energy. The reaction results in the explosion of the fireworks.
The fireworks have been produced in varying colors due to the chemicals present in them. The chemical change for the transition from one substance to another and results in the colorful lights.
The chemicals responsible for the red flame have been strontium, the green flame has been produced by barium, and sodium has been responsible for the yellow flame.
For more information about aerial fireworks, refer to the link:
Strontium or Lithium compounds produce red color, Barium compounds produce green color, and Sodium compounds produce yellow color in aerial fireworks.
The elements responsible for producing red, green, and yellow colors in aerial fireworks are:

Using the combined gas law, we find that the new pressure of the gas sample, after it's compressed and heated, is approximately 353.8 kPa.
The subject of this question is gas laws, specifically the combined gas law which states that the ratio of the product of pressure and volume and the absolute temperature of a gas is constant. We apply this law to calculate the new pressure of the gas sample. Starting from the conditions of STP (Standard Temperature and Pressure, defined as 273.15 K and 1 atm i.e., 101.325 kPa), the volume of gas is decreased from 700.0 mL to 200.0 mL and the temperature is increased from 273.15 K to 30.0 degrees Celsius (or 303.15 K in absolute terms).
We set up the equation P1*V1/T1 = P2*V2/T2, where P1 = 101.325 kPa, V1 = 700.0 mL, T1 = 273.15 K, V2 = 200.0 mL, and T2 = 303.15 K. Plugging in these numbers and solving for P2 (the new pressure), we get P2 = P1*V1*T2 / (T1*V2) = 101.325 kPa * 700.0 mL * 303.15 K / (273.15 K * 200.0 mL) = approximately 353.8 kPa.

(2) melting and evaporating
(3) condensation and sublimation
(4) condensation and deposition
Melting and evaporating are the physical changes that are endothermic. Therefore, the correct option is option 2.
Physical modifications are those that modify a chemical substance's shape yet do not affect its chemical content. Physical changes may normally be utilised to separate compounds to chemical elements and simpler compounds, but they cannot be utilised for separate mixtures to their individual components. When something changes physically but not chemically, it is said to have undergone a physical transformation. This contrasts to the idea of a chemical change, when a material's composition changes or a substance or substances mix or separate to generate new compounds. Melting and evaporating are the physical changes that are endothermic.
Therefore, the correct option is option 2.
