Answer:
Specific heat of metal of the metal is 0.8394J/g°C
Explanation:
The heat the water gain is the same losing for the metal. The equation is:
m(Metal)*ΔT(Metal)*S(Metal) = m(Water)*ΔT(Water)*S(Water)
<em>Where m is mass: 66.0g water and 28.5g Metal</em>
<em>ΔT is change in temperature: (95.25°C-27.84°C) = 67.41°C for the metal and (27.84°C - 22.00°C) = 5.84°C for the water</em>
<em>And S is specific heat of water (4.184J/g°C) and the metal</em>
<em />
Replacing:
28.5g*67.41°C*S(Metal) = 66.0g*5.84°C*4.184J/g°C
S(Metal) = 0.8394J/g°C
<h3>Specific heat of metal of the metal is 0.8394J/g°C</h3>

SOLUTION :
Law of conservation of Mass States that "Mass is neither created, nor destroyed".
→ Like Mass of Reactants = Mass of products.
REACTANTS :
- Mass of Sodium Carbonate(given) = 5.3g
- Mass of ethanoic acid(given)= 6g
The total mass of reactants:
= 5.3 + 6
= 11.3g
<h3>•Products are :</h3>
- Mass of Carbon Dioxide = 2.2g
- Mass of Sodium ethanoate = 8.2g
The total mass of products is :
= 2.2 + 0.9 + 8.2
= 3.1 + 8.2
= 11.3g
Hence the, Mass of Reactants = Mass of products
∴ The given reaction is in agreement with the law of conservation.
