Please help How much heat in kilojoules is required to warm 10.0 g of ice, initially at -20.0 ∘C, to steam at 125 ∘C. The heat capacity of ice is 2.09 J/(g⋅∘C) and that of steam is 1.84 J/(g⋅∘C).

particle   p is an electron and particle q is a neutron

a) the particles of the chair are strongly held together.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
