Answer:
reduced
Explanation:
To win the metallic product from the oxide, it demands that the metal be reduced.
During reduction a metal will:
- gain electrons.
- there would be removal of oxygen from the specie
- there would be decrease in oxidation number of the atom
- decrease in the number of electronegative atom surrounding the element.
The specie that is reduced will become the oxidant and reducing agent in the chemical reaction.
The recessive trait disappears in an offspring that is genetically crossed. TRUE.

Answer:
Yes; mayonnaise is a liquid.
Explanation:
This is because, when you smear it on a slice of bread, it moves freely. Like ketchup, when you put it on your plate. Is ketchup a liquid? Yes, it is. So yes, mayonnaise is most definitely a liquid.

Answer : The negative value indicate about the reaction is exothermic and heat is released.
Explanation :
Enthalpy of a reaction (ΔH): It is defined as the energy change that takes place during the chemical processes. It is represented as, ΔH.
If the heat is absorbed during the chemical process then the enthalpy of reaction is positive.
If the heat is released during the chemical process then the enthalpy of reaction is negative.
That means,
When the value of enthalpy of reaction is negative then the heat is released and the reaction will be exothermic reaction.
When the value of enthalpy of reaction is positive then the heat is absorbed and the reaction will be endothermic reaction.
