Explanation:
Answer:
The statement is TRUE.
Explanation:
In endothermic reactions, heat is absorbed (imagine that heat would be a reactive in the reaction). The enthalpy (H) of the products is greater than that of the reagents and the deltaH is positive. An example of this reaction is the decomposition of H20:
2H20 -> 2H2 + 02
The answer is electrolyte.
That is electrolyte is the type of minerals that is associated with maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential.
Sodium, potassium and chlorides are the macrominerals that are known as the electrolytes, that are very important for the function says maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential .
Electrons are not a part of the mass number,
Tin has 50 Electrons
50 Protons, and 69 Neutrons are in a Tin Atom
