It is an Alkene because it has a double bond, so it’ll have “ene” at the end. The simplest Alkene has 2 carbons.
2 carbons = “eth”
Look at that! Two carbons! It must be “ethene”
The molar mass of a 0.314-gram sample of gas having a volume of 1.6 l at 287 k and 0.92 atm. is 5.23 gram.
<h3>What is an Ideal Gas ?</h3>
An Ideal Gas is a law for ideal gas which states that the product of Pressure and Volume is equal to the product of the moles of sample, universal gas constant and temperature.
PV = nRT
The given data in the question is
Pressure = 0.92 atm
Volume = 1.6 l
Temperature = 287 K
0.92 * 1.6 = n * 287 * 0.082
n = 0.06 moles
0.06 = 0.314 / molecular weight
molecular weight = 0.314/0.06
Molecular weight = 5.23 gm
Molar mass = 5.23 gm.
The temperature and pressure conditions at which the gas behaves like an ideal gas is 273 K and 1 atm.

Answer:
The answer to your question is 2.92 x 10⁻⁶ g
Explanation:
Data
mass of K = ?
atoms of K = 4.50 x 10¹⁶
Process
To answer this question just remember that the atomic mass of any element is equivalent to Avogadro's number.
1.- Look for the atomic number of Potassium
Atomic number = 39.10 g
2.- Use proportions and cross multiplication
39.10 g of K --------------- 6.023 x 10²³ atoms
x ----------------4.50 x 10¹⁶ atoms
x = (4.50 x 10¹⁶ x 39.10) / 6.023 x 10²³
-Simplify
x = 1.7595 x 10¹⁸ / 6.023 x 10²³
-Result
x = 2.92 x 10⁻⁶ g
Chemical Potential Energy is released when chemical bonds between atoms are broken (like covalent and ionic) and is released mainly as thermal
Elastic Potential is released when the molecules in the material are allowed to go back to there original form, and is released mainly as kinetic
Answer:
The correct answer is - D. It gets rid of pathogens that invade the body.
Explanation:
Like all other organ systems, the immune system is an organ system that involves several special organs that helps in fighting any foreign object or infection that invades our body. This organ system produces specific cells or chemicals to fight or kill the microbes, and unnatural change takes place in the body.
The organs involved in the immune system are lymphocytes or white blood cells, the complement system, antibodies, the lymphatic system the thymus, bone marrow, and the spleen.
All these combinedly helps in fighting, killing the microbes or infections that occur in the body, and correct the physiological changes that occur in the body to get rid of pathogens that invade the body.
