Metalloids share many similar properties including: They appear to be metal in appearance, but are brittle. They can generally form alloys with metals. Some metalloids such as silicon and germanium become electrical conductors under special conditions. Mark me brainliest please
Answer:
Its melting point is 17 °C.
Explanation:
- The melting point of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium.
<em>So, the melting point is 17 °C.</em>
And this is shown in the figure attached.
Answer: The molar concentration of oxygen gas in water is
.
Explanation:
Partial pressure of the
gas = 685 torr = 0.8905 bar
1 torr = 0.0013 bar
According Henry's law:

Value of Henry's constant of oxygen gas at 20 °C in water = 34860 bar


Let the number of moles of
gas in 1 liter water be n.
1 Liter water = 1000 g of water
Moles of water in 1 L 




Molar concentration of oxygen gas in 1 L of water:

The molar concentration of oxygen gas in water is
.
