The chemical change can occur can be find if you mix the two solids in one direction
Electronegativity is the property of the element to attract electrons to its nucleus. The trend of electronegativity in the periodic table is decreasing from right to left and decreasing from top to bottom. hence from the given elements, the element with the highest electronegativity should be A.beryllium
Explanation:
Reactants can be referred to as starting materials for a chemical reaction. They undergo a change to form products. Reactants are usuallyconsumed in the reaction process.
Reactants are written at the left side before the arrow sign in a reaction.
Products are the ending materials of a reaction. They are what is left after the reactants has been consumed.
Prpducts are written on the right side after the arrow sign in a reaction
Basically, a reaction is given as;
Reactants --> Products
A + B --> C + D
A and B are reactants and C and D are products
In the reaction;
“carbon plus oxygen makes carbon dioxide”
C + O2 --> CO2
The reactants are; C and O2.
The product is CO2
Specific heat is measuring how much heat is needed to raise one gram of a substance by one degree Celsius. Therefore, the substance with the lowest specific heat requires the least amount of energy to raise its temperature. This means if all of the substances got the same amount of heat, the substance with the lowest specific heat's temperature would raise the most. Or, if each substance was exposed to constant heat, the substance with the lowest specific heat would heat up the fastest. Since copper has the lowest specific heat, the answer is copper.
