What is the name of the high energy compound that cells use directly to fuel other chemical reactions?
irga5000 [103]

Answer:-

ATP Adenosine Triphosphate

Explanation:-

ATP is the name of the high energy compound that cells use directly to fuel other chemical reactions. It is found in all cells. In the mitochondria, every "turn" of the citric acid cycle produces one equivalent of ATP.

ATP + H 2O → ADP + Pi+ energy

ADP is adenosine monophosphate.

If I have 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 Liters, what is the temperature in Kelvin(K)
kvv77 [185]

Answer:

205 K (to 3 significant figures)

Explanation:

Assuming that 4 moles of the gas behaves like an ideal gas and obey the kinetic molecular theory.

Let's apply the ideal gas law, pV= nRT.

Here p denotes the pressure of the gas, V is for volume, n is the number of moles of the gas, R is the universal gas constant and T is the temperature.

Substitute the given information into the equation:

5.6 atm ×12 L= 4 mol ×R ×T

Since pressure is in atm and volume is in L, we can use R= 0.08206 L atm K⁻¹ mol⁻¹.

5.6 atm ×12 L= 4 mol ×0.08206 L atm K⁻¹ mol⁻¹ ×T

T= 67.2 ÷0.32824

T= 204.73 (5 s.f.)

T= 205 K (3 s.f.)
