The specific heat of a material is 0.137 J/g°C.
<u>Explanation:</u>
The specific heat formula relates the heat energy required to perform a certain reaction with the mass of the reactants, specific heat and the change in temperature during the reaction.
Q = mcΔT
Here m is the mass, Q is the heat energy required, ΔT is the change in temperature and c is the specific heat.
So, if we have to determine the specific heat of the object, then we have to determine the ratio of heat required to mass of the object with change in time, as shown below.
As mass of the object m is given as 35 g and the energy is said to be absorbed so Q = 96 J.
The temperature values given should be changed from kelvin to celsius first. So, initial temperature 293 K will become 293-273.15 = 19.85°C.
Similarly, the final temperature will be 313 - 273.15 = 39.85°C.
Then, ΔT = 39.85-19.85 = 20 °C
Then,
So, the specific heat of a material is 0.137 J/g°C.
It is actually something standardized more so than theoretical, however in terms of atoms in general the electrons are based on the amount of electronic shells that an atom has and the amount of electrons that atom can accommodate. In the case of sodium, it has three shells with 2 electrons on the first shell which is the maximum, 8 on the second shell which is also the max and 1 on their final shell
So simply put an ATOM of Sodium (Na) has 23 electrons because it has 23 protons which is a fact

The independent variable in the experiment is the soap and the dependent variable in the experiment is the number of water drops on the surface of the penny. The control is the penny without soap.
So in your question that ask to calculate the Ph result of the resulting solution if 26 ml of 0.260 M HCI(aq) is added to the following substance. The the result are the following:
A. The result is pH= 14-pOH
B. There are 10ml of 0.26m HCL excees in this reaction so the answer is log(H)+
