I need more information to be able to answer this question
Computers can't really detect such a low intensity.......?, I hope I'm right.
Answer:
i hope it helps
Explanation:
This reaction involve an acid (HCl) reacting with a base (NaOH), producing a salt (NaCl) and water. Therefore it's a neutralization reaction.
Answer:
Thermite Reaction
Explanation:
The reaction between iron(III) oxide and aluminum produces aluminum oxide and iron. The chemical equation of the reaction is: This reaction is known as a thermite reaction and is highly exothermic. The large amount of heat released is enough to melt oxygen and aluminum.
The percent by mass : 6.3%
<h3>Further explanation</h3>
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight/volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
mass of potassium nitrate = 8.4 g⇒solute
- mass of solution = mass of solute+mass of solvent(water)
mass of potassium nitrate + mass of water = 8.4 g + 125 g =133.4 g
Percent by mass of the solute :
