Hello there!
In this case, according to the given information, it is possible to recall the equation to calculate the heat, Q, in these calorimetry problems as shown below:
Thus, given the absorbed heat, mass and temperatures, we can easily calculate the specific heat of the metal as shown below:
Then, by plugging in we obtain:
Best regards!
The volume of the nail since it is an irregular figure you can't measure it like a regular object.
Answer:
The answer to your question is: c) ATP
Explanation:
a) Carbon dioxide this molecule is a product of cell respiration so is very important for the cells but it isn't a form of energy cash, then this option is wrong.
b)Glucose: this molecule is used in the cell respiration process, from it the cell obtain ATP, but it isn't the energy cash for the cell.
c) ATP: this molecule is used by the cell to obtain energy, when an enzyme cuts off the phosphate bonds of this molecule it gets energy so this is the right answer.
d) Oxygen: oxygen is very important in the cell respiration process but It isn't usedas a energy cash.
