Answer:A) V = 16.892 ml
Explanation:
M1 * V1 = M2 * V2
14.8 M * V1 =0.250 M * 1000 ml
V1 = 16.892 ml
Answer:
D. protons that is the answer
Answer:
aluminium chloride, ferric chloride,
so C is correct I guess
Answer:
About 3.5 kJ.
Explanation:
Recall the heat transfer equation:
Where <em>q</em> is the heat; <em>m</em> is the mass of the substance; <em>C</em> is its specific heat; and Δ<em>T</em> is the change in temperature.
The given specific heat of iron is 462 J/kg -°C.
Substitute and evaluate. Ensure correct units:
Therefore, the block of iron absorbed about 3.5 kJ of heat.
