M = 4 g = 4/1000 kg = 0.004 kg, θ₂ = 21.0°C, θ₁ = 0°C , c = 0.44kJ/kg°C,
Q = mc(θ₂ - θ₁)
Q = 0.004*0.440*(21 - 0)
Q = 0.03696 kJ
0.03696 kJ<span> of heat is absorbed.</span>
When nonmetal atoms with differing electronegativities react, they form molecules with polar covalent bonds. Each element has an electronegativity value, which is a measure of the ability of an atom to attract and share electron pairs of another atom. Are you looking for the electronegativity value? I think this is correct
