Answer:
E. All of the above are true.
Explanation:
<em>Which of the following statements is TRUE?</em>
<em>A. State functions do not depend on the path taken to arrive at a particular state.</em> TRUE. State functions like enthalpy (ΔH) and internal energy (ΔE) do not depend on the trajectory, but on the initial and final state.
<em>B. Energy is neither created nor destroyed, excluding nuclear reactions.</em> TRUE. Only in nuclear reactions can energy (E) can be transformed in matter (m) and vice-versa according to Einstein equation: E = m . c² (c is the speed of light).
<em>C. ΔHrx can be determined using constant pressure calorimetry.</em> TRUE. The enthalpy of reaction is the heat involved at constant pressure.
<em>D. ΔErx can be determined using constant volume calorimetry.</em> TRUE. The internal energy of reaction is the heat involved at constant volume.
Answer:
Nickel(II) chloride is produced by dissolving nickel or its oxide in hydrochloric acid. It is usually encountered as the green hexahydrate, the formula of which is usually written NiCl2⋅6H2O. When dissolved in water, this salt forms the metal aquo complex [Ni(H2O)6]2+.
The Dalton’s theory is really interesting see you got 6 molecules of water
A. The elements melting point temperatures.
