Answer:
0.5667 M ≅ 0.57 M.
Explanation:
- It is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles of the solution after the dilution.
<em>(MV) before dilution = (MV) after dilution.</em>
M before dilution = 1.5 M, V before dilution = 340 mL.
M after dilution = ??? M, V after dilution = 340 mL + 560 mL = 900 mL.
∴<em> M after dilution = (MV) before dilution/(V) after dilution</em> = (1.5 M)(340 mL)/(900 mL) = <em>0.5667 M ≅ 0.57 M.</em>
Answer:
A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity. The rotor is attached to the turbine shaft and rotates at a fixed speed.

Metal period- Reactivity Gets smaller as you move from left to right.
Group- Reactivity gets bigger as you move down a group.
Explanation:
(a):their malleability:
>iron making. iron worker heat the meat and hammer it to give them the desired shape.
> in the jewelry making process, like the gold or silver you wear are results due to the malleability of metal
(b):their ductility:
>for the making of high tension cable that connects different cities for transferring of electricity.
>for making wire gauze
(c):their ability to conduct electricity:
>for lighting up your house with light bulbs
>for using cooking stoves
>to make refrigerator work.
