Answer:
products and reaction
Explanation:
Products
1. FeSO4 and Cu
2. ZnSO4 and Fe
3. CaCl2 and H2
Reactions
1. Fe + CuSO4 → FeSO4 + Cu
2. FeSO4 + Zn → ZnSO4 + Fe
3. 2HCl + Ca → CaCl2 + H2
Each element is made up of only one kind of atom
The degree that a solvent dissolves a given solute is known as its solubility. Ethyl alcohol is highly soluble in water, for example. Vinegar is very insoluble in oil, and the two substances will quickly separate into two layers even after being shaken well. Hope this helps! Mark brainly please!
Answer:
![V_{concentrated}=0.042L=4.2mL](https://tex.z-dn.net/?f=V_%7Bconcentrated%7D%3D0.042L%3D4.2mL)
Explanation:
Hello,
In this case, since in a dilution process the moles of the solute must remain unchanged, we use the volumes and molarities as shown below:
![M_{diluted}V_{diluted}=M_{concentrated}V_{concentrated}](https://tex.z-dn.net/?f=M_%7Bdiluted%7DV_%7Bdiluted%7D%3DM_%7Bconcentrated%7DV_%7Bconcentrated%7D)
Clearly, the concentrated solution is 12M and the diluted solution is 0.5 M, thus, the volume of the concentrated solution we should take is:
![V_{concentrated}=\frac{M_{diluted}V_{diluted}}{M_{concentrated}} =\frac{0.5M*1.0L}{12M}\\ \\V_{concentrated}=0.042L=4.2mL](https://tex.z-dn.net/?f=V_%7Bconcentrated%7D%3D%5Cfrac%7BM_%7Bdiluted%7DV_%7Bdiluted%7D%7D%7BM_%7Bconcentrated%7D%7D%20%3D%5Cfrac%7B0.5M%2A1.0L%7D%7B12M%7D%5C%5C%20%5C%5CV_%7Bconcentrated%7D%3D0.042L%3D4.2mL)
Best regards.
multimeter is an electronic instrument used to measure the three basic electrical characteristics: voltage, current and resistance. It has multiple functions and acts like ohmmeter, voltmeter and ammeter and also used for household wiring, electric motors, testing batteries and power supplies.
