The heat required by the cube of iron has been 602.64 J.
The specific heat has been given as the amount of heat required to raise the temperature of 1 gram of substance by 1 degree Celsius.
The heat required has been expressed as:
<h3 /><h3>Computation for the heat required by Iron sample</h3>
The mass of the sample has been given as 55.8 g
The specific heat of tin has been,
The change in temperature, () has been:
Substituting the values for the heat required:

Answer:
it is false Sodium acetate NEVER precipitates
T he Richter scale is used to rate the magnitude of an earthquake -- the amount of energy it released. This is calculated using information gathered by a seismograph. The Richter scale is logarithmic, meaning that whole-number jumps indicate a tenfold increase. In this case, the increase is in wave amplitude.
CO2: 12.0107 + 15.9994(2) = 44
NH3: 14.0067 + 1 (3) = 17
1.55 (17/44) = .599g
Explanation -
<em>First: Ice will not evaporate in boiling water, it will melt. The input of energy is required to overcome the attractive forces between water molecules at the boiling point). This is in excess of the heat energy needed to raise water tothe temperature of the boiling point.</em>
