In a closed system, heat should be conserved which means that the heat produced in the calorimeter is equal to the heat released by the combustion reaction. We calculate as follows:
Heat of the combustion reaction = mC(T2-T1)
= 1 (1.50) (41-21)
= 30 kJ
Answer: divide by 946.353
= 1.58 x 10^-4 or 0.000159
Explanation:
<h3><u>Answer;</u></h3>
Cations are much smaller than their corresponding parent
<h3><u>Explanation;</u></h3>
- Parent atom has more electrons and thus the effective nuclear charge on each electron is less.
- When a cation is formed electron(s) is/are lost. Thus the effective nuclear charge or simply put, the attraction of the nucleus towards the electrons increases. Therefore, due to greater pull, the nucleus pulls the shells towards it, there by reducing the size, which makes cations smaller than their corresponding parent.
The body gets rid of acid in a chemical pathway that requires oxygen. The correct answer is B, oxygen.
The answer is C. They lower the activation energy of an elementary step of a reaction
This makes the reaction rate to increase since less energy is required to make a reaction occur.
