Answer:
All of alpha-ketoglutarate formed in the citric acid cycle would contain the radioactive 
while none of succinate would contain , and all of carbon dioxide released would contain .
Explanation:
When oxaloacetate in the citric acid cycle is labeled with in carboxyl carbon atom which is farthest from keto group, alpha ketoglutarate formed from this oxaloactetate has the full radioactive label. In the next step, the carboxylic group (that contains the ) is eliminated in the form of the release of the carbon dioxide and succinate is formed. Succinate thus will not have radioactivity. 
released had all the radioactivity.
The molarity of the solution made by dissolving 0.05 mole of HCl in 2 L of H₂O is 0.025 M
<h3>What is molarity? </h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the molarity </h3>
- Mole of HCl = 0.05 mole
- Volume = 2 L
- Molarity =?
Molarity = mole / Volume
Molarity = 0.05 / 2
Molarity = 0.025 M
Thus, the molarity of the solution is 0.025 M

Answer:
Postulate: Gas particles are extremely small and are far apart.
The activities can be used to demonstrate the postulate is :
<u>Observing colored gas spreading into an inverted jar placed on top of a jar containing the gas</u>
<u />
Explanation:
colored gas spreading into an inverted jar placed on top of a jar containing the gas:
This occur because of two reasons:
1. <em><u>The Gaseous particles are largely spaced . There is large distance between the gases molecule</u></em>
<em><u>2. The gases are in continuous motion . Hence they posses very high kinetic energy . This is the reason they mixes quickly if placed in a jar.</u></em>
<em><u>This occur by the process of diffusion. </u></em>
Diffusion of Gases: The intermixing of particles from the region of high concentration to low concentration.
The coloured gas goes into the space between the gaseous molecule present in the jar.(Gases are far apart)
As soon as the coloured gas is mixed in the jar , It spread quickly by diffusion because , The gaseous particles are extremely small and are far apart.
I'm guessing its Sublimation point of water
Hope this helps
The Hydrogen ion concentration of a pH 3.8 solution would be higher than that of a solution with a pH of 6.2. This is because since the pH scale measures the concentration of Hydrogen ions. We know that a pH range of less than 7 is considered acidic and greater than 7 is basic. If a solution is more acidic it would possess more hydrogen ions than if it weren't. In this case a pH value of 3.8 is more acidic than pH 6.2.
