The specific heat of the unknown metal is 0.859 J/g⁰C.
<h3>Specific heat of the unknown metal</h3>
Heat lost by the unknown metal = Heat gained by water
m₁c₁Δθ₁ = m₂c₂Δθ₂
where;
- c₁ is specific heat of the unknown metal
- c₂ is specific heat of water
(15)(c₁)(99 - 26) = (75)(4.18)(26 - 23)
1095c₁ = 940.5
c₁ = 940.5/1095
c₁ = 0.859 J/g⁰C

Answer:
NOCl structure has geometry of trigonal planar and N has sp2 hybridisation. N is the central atom because it is less electronegative than O atom and Cl cannot be the central atom because it only forms a single bond. So, the central atom of NOCl is N and its hybridisation
Answer:
Intensity
Explanation:
The correct answer is -Intensity
Reason -
Intensity has no affect on whether or not the photoelectric effect occurs.
As frequency , wavelength are inversely proportional.
Inter molecula force
1- hydrogen bond
2- ion bond
3- dipole dipole
4- dipole bond or van der wael
but not all dipole dipole has the same strength
