The type of mixture that is formed when one substance dissolves into another and fills the spaces between other kinds of molecules is a colloidal mixture. It is a type of mixture where a solute is dispersed evenly in a solvent. The particles' sizes range from 1 to 1000 nm.
There is no hydrogen in ammonium sulfide it is just 1 ammonium and 1 sulfer
Answer:
Explanation:
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and
for the reaction comes out to be negative.
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and
for the reaction comes out to be positive.
As the heat is absorbed the reactants , the reaction is endothermic and
for the given endothermic reaction will be +127 KJ
Answer:
Ca
Explanation:
Ionization energy decreases from top to bottom and increases from left to right on the periodic table
These are known as adaptions which causes evolution
