How much thermal energy (q) is required to heat 15.2g of a metal (specific heat=0.397j/c) from 21.0c to 40.3c? show steps .

Q = ?

Cp = 0.397 J/ºC

Δt =  40.3 - 21.0 => 19.3 ºC

m = 15.2 g

Q = m x Cp x Δt

Q = 15.2 x 0.397 x 19.3

Q ≈ 116.46 J

hope this helps! 

Ifound this on google “these two compounds have a different ionic structure. caesium ion is larger in size when compared to the sodium ion. the charge gets more area to spread out evenly. so caesium chloride has a lower melting point than sodium chloride.” i hope this you for what your looking for
