How much energy is released when 65.8 g of water freezes

Delvig [45]

The amount of energy released is calculated by the product of heat of fusion and mass. The formula of amount energy released is given by: $q= L\times m$ (1)

Here,

q is amount of energy released L is heat of fusion ( $334 J/g$ ) m is mass of water Put all the given values in equation (1)

$q= 334 J/g \times 65.8 g$

$q= 21977.2 Joules$ ≅ $21977 Joules$

$q= 21977 Joules$

Thus, amount of energy released is $21977 Joules$

Using the following equation for the combustion of octane calculate the heat associated with the formation of 100.0 g of carbon

natali 33 [55]

Answer:

The right solution is "-602.69 KJ heat".

Explanation:

According to the question,

The 100.0 g of carbon dioxide:

= $\frac{100.0 \ g}{114.33\ g/mole}$

= $0.8747 \ moles$

We know that 16 moles of $CO_2$ formation associates with -11018 kJ of heat, then

0.8747 moles $CO_2$ formation associates with,

= $-\frac{0.8747}{16}\times 11018 \ KJ \ of \ heat$

= $-0.0547\times 11018$

= $-602.69 \ KJ \ heat$
