Answer: ATP is the energy currency molecule which is required for cellular processes.
Explanation:
When the cell require metabolic energy to perform a particular a task. From the ATP or adenosine triphosphate molecule one of three phosphate molecule gets displaced and liberates the resulting molecule becomes adenosine diphosphate or ADP. The phosphate molecule is used by the cell to perform different cellular and metabolic functions as a source of metabolic energy. The phosphate is released by the hydrolysis of the phosphoanhydride bond with the other phosphate group.
Hello there what is the question?
Answer:
1,620 J.
Explanation:
- The amount of heat added to a substance (Q) can be calculated from the relation:
<em>Q = m.c.ΔT.</em>
where, Q is the amount of heat released from ethanol cooling,
m is the mass of ethanol (m = 60.0 g),
c is the specific heat of ethanol in the liquid phase, since the T is cooled below the boiling point and above the melting point (c = 1.0 J/g °C),
ΔT is the temperature difference (final T - initial T) (ΔT = 43.0 °C – 70.0 °C = - 27.0 °C).
<em>∴ Q = m.c.ΔT</em> = (60.0 g)(1.0 J/g °C)(- 27.0 °C) = - 1620 J.
<em>The system releases 1620 J.</em>
Answer:
Yeild of CO2 is approximately 54g
Explanation:
Using reaction stoichiomety and coeeficients, and knowing O2 is limiting reactant, 54 g of CO2 is produced.
