Answer:
Double replacement or double decomposition
Explanation:
In the reaction below, a double replacement or double decomposition has occurred.
2Na₃PO₄ + 3CaCl₂ → 6NaCl + Ca₃(PO₄)₂
This reaction occurs mainly between two ionic substances.
The reaction involves an actual exchange of partners to form new compounds. For example;
AB + CD → AD + CB
One of the following conditions below serves as the driving force for double replacement reactions:
- Formation of an insoluble compound or precipitate.
- Formation of water or any other non-ionizing compound
- Liberation of a gaseous product.
Answer: hypodermis
Explanation:
The very bottom layer of the skin is the hypodermis. It contains the fat cells, or adipose tissue, that insulate the body and help it conserve heat.
God bless you!!
Soluble means it can be dissolved
Insoluble means it can't be dissolved
