Answer:
The chloride formed when iron reacts with hydrochloric acid is iron (II) chloride, also known as iron dichloride. The reaction between iron and hydrochloric acid is slower than the reaction with zinc, with much smaller hydrogen bubbles produced.
Answer:
283549.68 J
Explanation:
From the question given above, the following data were obtained:
Mass (M) = 2.7 Kg
Initial Temperature (T₁) = 5.4 °C
Final temperature (T₂) = 30.5 °C
Specific heat capacity (C) = 4184 J/KgºC
Heat (Q) =?
The amount of heat energy needed can be obtained as follow:
Q = MC(T₂ – T₁)
Q = 2.7 × 4184 × (30.5 – 5.4)
Q = 11296.8 × 25.1
Q = 283549.68 J
Thus, the heat energy needed is 283549.68 J
