Answer
The second part of the theory says all atoms of a given element are identical in mass and properties. The third part says compounds are combinations of two or more different types of atoms. The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.

Answer:
s an example, the ground state configuration of the sodium atom is 1s22s22p63s1, as deduced from the Aufbau principle (see below). The first excited state is obtained by promoting a 3s electron to the 3p orbital, to obtain the 1s22s22p63p1 configuration, abbreviated as the 3p level.
Explanation:
Answer: The reaction of 1 mol of C to form carbon monoxide in the reaction 2 C(s) + O2(g) ( 2 CO(g) releases 113 kJ of heat. How much heat will be released by the combustion of 100 g of C according the the above information? According to the balanced chemical equation;
Explanation:
It has 7.22 moles.... mole =mass/molar mass
molar mass of H2O=18
130/18=mole
