Answer : The current will flow more easily and quickly through the copper wire, on application of voltage because copper is a metal which is good conductor of heat and electricity.
In case of germanium it is a semi-conductor means it will behave as a conductor under certain circumstances.
So if we take same length and same thickness of both the wires, current is more likely to flow through the copper wire than the germanium wire.
Answer:
electrons can bond atoms together
Explanation:
when two atoms share electrons,they are locked together by that sharing.These are called covalent bonds...but when an atom gives one of its electrons to another atom ,they are held together by electric forces.HOPE THAT HELPED☺
Answer:
Explanation:
The given pH = 8.55
Unknown:
[H₃O⁺] = ?
[OH⁻] = ?
In order to find these unknowns we must first establish some relationship.
pH = -log[H₃O⁺]
8.55 = -log[H₃O⁺]
[H₃O⁺] = inverse log₁₀(-8.55) = 2.82 x 10⁻⁹moldm⁻³
To find the [OH⁻],
pH + pOH = 14
pOH = 14 - pH = 14 - 8.55
pOH = 5.45
pOH = -log[OH⁻]
[OH⁻] = inverse log₁₀ (-5.45) = 3.55 x 10⁻⁶moldm⁻³
The solution is basic because it has more concentration of OH⁻ ions compared to H⁺ ions.
Answer:
The pH of the solution is 3.0
Explanation:
Considering:
Or,
Given :
For :
Molarity = 0.0030 M
Volume = 100 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 100×10⁻³ L
Thus, moles of :
Moles of = 0.0003 moles
Volume added = 200 mL
Total volume = 200 + 100 mL = 300 mL = 0.3 L
Thus,
SInce, it is strong acid. Thus, [H⁺] = 0.001 M
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺] = - log 0.001 = 3.0
<u>The pH of the solution is 3.0</u>
