The amount of moles in 3.34 x10³⁴ formula unit of Cu(OH)₂ is 5.55 × 10¹⁰ moles
<u><em>calculation</em></u>
The amount of moles is calculated using the Avogadro's law constant
That is 1 moles = 6.02 × 10²³ formula units
? moles = 3.34 × 10³⁴ formula units
<em>by cross multiplication</em>
= {1 mole ×3.34 ×10³⁴ formula units ] / 6.02 × 10²³ formula units} = 5.55 ×10¹⁰ moles
Uses Of Periscope
It is used in submarines to determine the distance of a torpedo and helps in deciding the right time for the attack.
It is used in a nuclear reactor to observe the chemical reactions that are taking place.
In military periscopes are used to observe from their hiding position. Hi
Liquid has a definite volume but no specific shape<span />
Answer: Fluorine has the highest ionization enthalpy.
Explanation: This is because the ionization energy decreases from top to bottom and increases from left to right. Also, ionization enthalpy is the amount of energy required by an isolated gaseous atom to lose an electron in its ground state.
Since fluorine needs just one atom to attain noble gas configuration so it will not want to lose any electron and hence a high amount of energy will be required to remove an electron from it.
Heat energy is the amount of heat there is in a substance. This may be cold heat or warm heat. Temperature is how hot or cold a substance is. So because there is a higher volume of heat in the iceberg, we say it has more heat energy.
