Answer:
Explanation: The key difference between Complete ionic and net ionic equation is that complete ionic equation gives all the ionic species participated in the chemical reaction whereas net ionic reaction gives the chemical species participated in the formation of the final product.
Answer A scientific law is a statement that describes what always happens under certain conditions in nature. An example of a scientific law is the law of gravity, which was discovered by Sir Isaac Newton. The law of gravity states that objects always fall towards Earth because of the pull of gravity.
Explanation:
<h2>Answer:</h2>
B) check to see if any energy was released during the reaction
<h3>Explanation:</h3>
Energy changes accompanying nuclear reactions are much larger. This energy comes from the destruction of mass. In a nuclear reaction, mass is not strictly conserved. Some of the mass is converted into energy, according to the equation E = mc2 and the order of energy evolved during a nuclear reaction is much higher than that of a chemical reaction. So, one of the significant way to determine weather the reaction is chemical or nuclear is to check how much energy was released during the reaction.
The unbalanced chemical reaction is
<span>Na (s) + H2O (g) yields NaOH (aq) + H2 (g)
By inspection,
There is 1 mole of Na in both sides
There is 2 moles of H in the left and 3 moles in the right side.
</span>There is 1 mole of O in both sides
<span>
We balance the reaction by:
</span>2Na (s) + 2H2O (g) yields 2NaOH (aq) + H2 (g)
The answer is 2
Answer:5.4 g / 13.6 g *100
Explanation:Its is the correct answer
