Manganese is an element.
Manganese is the 25th element on the periodic table. As it is an element, it means it cannot be separated or broken down into anything simpler, even by chemical methods such a electrolysis.
In additional, compound is where 2 or more elements are chemically bonded together, which usually involves heat, while mixture is where 2 or more elements or Compounds mixed together in any proportions.

Gazelles are hunted and eaten by the park's wild dogs. Lions are a predator of both wild dogs and gazelles. Which of the following food webs best represents the relationships described above? lion lion wild dog - wild dog gazelle gazelle grass grass lion lion wild dog wild dog gazelle gazelle grass grass
Matter is anything that occupies space and has mass.
Answer:
22.6According to the law of conservation of mass, the total mass of reactants should be equal to the total mass of products. Here, total mass of reactants= 11.3+11.3=22.6
•
• • Mass of Hcl produced=22.6 g

![\boxed {\boxed {\sf 4.8 \ M \ KCl}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%204.8%20%5C%20M%20%5C%20KCl%7D%7D)
Explanation:
The molarity of a solution is found by dividing the moles of solute by the liters. of solvent.
![molarity=\frac{moles}{liters}](https://tex.z-dn.net/?f=molarity%3D%5Cfrac%7Bmoles%7D%7Bliters%7D)
We know the solution has 3.6 moles of potassium chlorine. We know there are 750 milliliters of solvent, but we need to convert this to liters.
- 1 liter is equal to 1000 milliliters. Set up a proportion.
- Multiply by 750 mL and the units of mL will cancel.
Now we know the moles and liters, so we can calculate molarity.
- moles= 3.6 mol KCl
- liters= 0.75 L
Substitute these values into the formula.
![molarity= \frac{3.6 \ mol \ KCl}{0.75 \ L}](https://tex.z-dn.net/?f=molarity%3D%20%5Cfrac%7B3.6%20%5C%20mol%20%5C%20KCl%7D%7B0.75%20%5C%20L%7D)
Divide.
![molarity= 4.8 \ mol \ KCl/ L](https://tex.z-dn.net/?f=molarity%3D%204.8%20%5C%20mol%20%5C%20KCl%2F%20L)
- 1 mole per liter is equal to 1 molar.
- Our answer of 4.8 moles of potassium chloride per liter is equal to 4.8 M KCl
![molarity= 4.8 \ M \ KCl](https://tex.z-dn.net/?f=molarity%3D%204.8%20%5C%20M%20%5C%20KCl)
The molarity of the solution is <u>4.8 M KCl.</u>
