Answer: Option 1, 4 and 5 describe acids accurately.

Explanation:

Option 1: Acids have a sour taste because of the concentration of $H^+$ ion.

Option 2: They are corrosive in nature, that is they are not at all gentle with the skin and fabric as some acids intend to burn skin such as $H_2SO_4$ is a strong acid which can burn skin as well as fabric.

Option 3: Acids need electrons to release $H^+$ ions and non-metals do not donate electrons hence, there is no reaction between a non-metal and an acid.

Option 4: All acids do contain hydrogen. They dissociate in the presence of water to produce $H^+$ ions.

$HCl\overset{H_2O}{\rightarrow} H^++Cl^-$

Option 5: Acids do conduct electricity that is they carry electrical charges. This was explained by Arrhenius. He said that the acids dissociate into $H^+$ ions, when it is dissolved in water. These ions hence acts as charge carriers in water.

What is the heat needed to raise the temperature of 24.7 kg silver from 14.0 degrees Celsius to 30.0 degrees Celsius? Specific h

ELEN [110]

Answer:

$Q=93.3kJ$

Explanation:

Hello,

In this case, by knowing that the heat due to a change of temperature is given by:

$Q=mCp\Delta T$

Whereas Q accounts for the heat, m for the mass, Cp the heat capacity and ΔT for the change in temperature. In such a way the required heat results:

$Q=24.7kg*236\frac{J}{kg^oC}*(30.0-14.0)^oC*\frac{1kJ}{1000J} \\Q=93.3kJ$

Best regards.
