<u>Answer:</u> There are 8 hydrogen atoms on the product side in the reaction.
<u>Explanation:</u>
Every balanced chemical equation follows law of conservation of mass.
This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This law also states that total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.
For the given reaction, the balance chemical equation follows:
<u>On reactant side:</u>
Number of Phosphorus atoms = 1
Number of Chlorine atoms = 5
Number of Hydrogen atoms = 8
Number of Oxygen atoms = 4
<u>On Product side:</u>
Number of Phosphorus atoms = 1
Number of Chlorine atoms = 5
Number of Hydrogen atoms = 8
Number of Oxygen atoms = 4
Hence, there are 8 hydrogen atoms on the product side in the reaction.
Only one dissolves lonic compounds often dissociate into ions solution, whereas covalently bonded molecules retain their molecule identity in solution.
Answer:
C2H5OH(l) + O2(g) → CO2(g) + ?H2O(l)
The coefficient should be 3
Explanation:
C2H5OH(l) + O2(g) → CO2(g) + ?H2O(l)
The chemical equation is a reaction between ethanol and oxygen . The reaction yield is carbon dioxide and water. Balancing the chemical equation requires one to make the number of atoms on the reactant side be equal to the number of atoms on the product side.
C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)
The hydrogen atom on the left hand side of the equation is 6. Therefore, the number of atom of hydrogen should be 6 on the right hand side. The number of oxygen atom on the left hand side is 7. Therefore, the number of Oxygen atom on the right hand side should 7 . Oxygen atom in carbon dioxide(right hand side) is 4 atoms, therefore, it requires 3 atoms of oxygen to make the oxygen atoms 7.
Using 3 as the coefficient of water in the equation will make hydrogen 6 and oxygen 3 .Adding the 3 oxygen to the already 4 atoms of oxygen in carbon dioxide will make oxygen 7 atoms
Answer:
science needs both ideas the hypothesis and facts the quantitative results to move forward
Explanation:
the two primary features of a scientific hypothesis are falsifiability and testability which are reflected in an If…then statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation
Answer:
The temperature remains constant. after the change occurs and temp remains the same
Explanation:
Remains constant because the phase change is absorbing the energy, after the phase change occurs it is then increasing in temperature again.
