Answer:
= 0.551J/(g°C)
Explanation:
Specific heat is the amount of heat to required to raise the temperature of 1 gram substance to 1° C
The formula
C = q / m × ΔT ______ (1)
where ,
C = specific heat
q = heat
m = mass
ΔT = change in temperature
mass of the stainless steel is m = 1.55g
heat of the stainless steel is q = 141 J
the change in temperature is ΔT = 178°C
substitute all the value in the equation (1)

0.0000297 kg would be the answer to ur question :)
Answer:
The answer to your question is 22.5 moles of H₂SO₄
Explanation:
Data
moles of H₂SO₄ = ?
moles of Al = 15
Balanced chemical reaction
2Al + 3H₂SO₄ ⇒ Al₂(SO₄)₃ + 3H₂
To solve this problem use proportions and cross multiplication. Use the coefficients of the balanced chemical reaction.
2 moles of Al ------------------- 3 moles of H₂SO₄
15 moles of Al ------------------ x
x = (15 x 3) / 2
x = 45/2
x = 22.5 moles of H₂SO₄
-Conclusion
22.5 moles of H₂SO₄ react completely with 15 moles of Al.
15.0 moles of silver chloride are produced.
