Answer:Four types of vaccines are currently available: Live virus vaccines use the weakened (attenuated) form of the virus. The measles, mumps, and rubella (MMR) vaccine and the varicella (chickenpox) vaccine are examples
Because there is a higher volume of heat in the iceberg. Heat enery is the amount of heat there is in a substance. it may be cold heat or warm heat
If 0.380 mol of barium nitrate is allowed to react with an excess of phosphoric acid, 0.127 moles of barium phosphate could be formed.
<h3>How to calculate number of moles?</h3>
The number of moles of a compound can be calculated stoichiometrically as follows:
Based on this question, the following chemical equation is given:
Ba (NO3)2+ H3PO4 → Ba3(PO4)2+ HNO3
The balanced equation is as follows:
3Ba(NO3)2 + 2H3PO4 → Ba3(PO4)2 + 6HNO3
3 moles of barium nitrate produces 1 mole of barium phosphate
Therefore, 0.380 moles of barium nitrate will produce 0.380/3 = 0.127moles of barium phosphate.

Answer:
most endothermic reactions
Explanation:
In endothermic reactions, the entropy of the environment decreases.
The entropy is the measure of the disorder of a specific system.
An endothermic reaction is every chemical reaction in which energy is absorbed.
In a comparison of an endodermic reaction in which energy is released in light or heat form.
