It has a variable composition. B) Its color is different than pure gold. C) The gold atoms are not arranged in a repeating pattern. D) It can be melted and transformed into a different substance.
The data indicates a direct relationship with a positive slope.
<h3>What is direct relationship?</h3>
Direct relationship is a type of relation in which if one factor increases the other will also increases and vice versa. This data represents direct relationship because the increase occur in one value causes increase of another value so we can conclude that the data indicates a direct relationship with a positive slope.

Answer:
false
Explanation:
A combustion reaction is a burning process that occurs in the presence of an oxidant and a fuel. It is usually an energy releasing procedure in which the temperature of the environment is greater than that of the reactants.
Not all combustion reactions are redox reactions
In a redox reaction, one specie is oxidized and the other becomes reduced simultaneously.
Redox reactions are usually facilitated by the transfer of electron. One specie loses electrons to be gained by another specie.
Certain atoms in a combustion reaction will have to change their oxidation state.
During combustion, during combustion reaction, there is no transfer of electrons between reactants . None of the molecules changes oxidation state. For example;
CH₄ + 2O₂ → CO₂ + 2H₂O
The algebraic sum of all oxidation number of all atoms in a neutral compound is zero.
In the reaction above, all the atoms in going from reactants to products have a net oxidation number of zero.
carbon on both sides is 0
oxygen is 0
Hydrogen is 0
So there is no transfer electrons
