Pure substance- a material that has constant composition. It has distinct chemical properties.
Element- a substance that cannot be broken down into any other substances.
Compound- substance made up of two or more different elements.
Photoelectron spectroscopy
Inefficiency of the material or engine causes the output work of a machine to be less
than the input work. It is governed by the second law of thermodynamics wherein
no product of work can produce 100 percent efficiency. Only the Carnot engine
can produce a 100 percent effieciency.
Answer:
The number of atoms on both sides of the expression is not balanced
Explanation:
Stated equation:
KClO₃ → KCl + O₂
The equation above does not obey the law of conservation of mass because the atoms on both sides of the expression are not the same.
The law of conservation of mass states that "in a chemical reaction, atoms are neither created nor destroyed, but are transformed by combining with one another";
Number of atoms
Elements Left hand side Right hand side
K 1 1
Cl 1 1
O 3 2
We see that the number of oxygen on both sides of the expression differs.
