Answer: 16700 Joules
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed = ?
m = mass of sand = 2 kg
c = heat capacity =
Initial temperature = =
Final temperature= =
Change in temperature ,
Putting in the values, we get:
16700 J of energy must be added to a 2-kilogram pile of it to increase its temperature from 40°C to 50°C
Answer:
Here are the equations for those reactions:
copper oxide + sulfuric acid → copper sulfate + water
CuO + H2SO4 → CuSO4 + H2O
copper carbonate + sulfuric acid → copper sulfate + water + carbon dioxide
CuCO3 + H2SO4 → CuSO4 + H2O + CO2
Copper oxide and copper carbonate are insoluble, so usually you add an excess (more than enough to react with all the acid) then filter the mixture. The excess solid stays in the filter paper as a residue. The copper sulfate solution drips through as a filtrate. This can be warmed to evaporate the water, leaving copper sulfate crystals behind.

Answer: chemistry is love ❤️ #bae
Explanation: ok just kidding. The dictionary says chemistry is the scientific discipline with elements and compounds of atoms, molecules, and ions
