Answer: They both have stages where they are born and die which is in the main sequence and supernova and in a human they are born in a womb and die of old age.
Explanation:
Answer:
The correct answer is 596.5 kJ.
Explanation:
The mass of ethanol or C2H5OH mentioned in the question is 20 gm.
The molar mass of ethanol is 46 g/mol.
The moles of the compound can be determined by using the formula,
n = weight of the compound/molar mass
= 20/46 = 0.435 moles
It is mentioned in the question that standard heat of combustion of ethanol is 1372 kJ/mole, that is, one mole of ethanol is producing 1372 kilojoules of energy at the time of combustion.
Therefore, the energy liberated by completely burning the 20 grams of ethanol is 0.435*1372 = 596.5 kJ.
Your answer to this question would be True.
Hope I helped:P
The correct answer for the question that is being presented above is this one: "C. solubility level." The <span>term defines the amount that a solute can dissolve into a solution is called the solubility level. The higher the solubility level, the faster it dissolves.</span>
