Name any two plants that are known as shrubs?

Explanation

We are given that
`Delta U = 742.7 kj mol^(-1)`
T = 298 K
We are to calculate `Delta H` at 298 K.
From the reaction, `NH_(2) CN(s) + (3)/(2) O_(2) (g) to N_(2) (g) + CO_(2) (g) + H_(2) O(L)`
`Delta U = 2 - (3)/(2) = (1)/(2)`
We know that
`Delta H = Delta U+ Delta n_(g) RT`
` = - 742.7 + (1)/(2) xx 8.314 xx 10^(-3) 298 = - 742 + 1.239 = - 741.5 kj mol^(-1)`.
