7. How much ice is left over if 46 kJ of energy is added to 175 g of ice?

velikii [3]

Answer:

$m_{leftover}=37g$

Explanation:

Hello!

In this case, since the melting process involves the heat added to the system, the heat of fusion and the mass of water:

$Q=m\Delta H_{fus}$

Thus, as it has been reported that the heat of fusion of ice is 333.6 J/g, we can compute the melted mass of ice as shown below:

$m=\frac{Q}{\Delta H_{fus}} =\frac{46000J}{333.6J/g}\\\\m=138g$

Thus, the ice leftover results:

$m_{leftover}=175g-138g\\\\m_{leftover}=37g$

Regards!

How should pure water be classified with respect to its electrical conductivity properties?

vovikov84 [41]

Pure water would be classified as non-conductor since it does not allow the flow of current into the solution. It does not contains any ions or free electrons so it cannot allow the flow of current into the system. It can allow current only when any impurities is present like salts.
