I would love to help but im not able to find where the questions are can you help with that?
<span>When ammonium nitrate, NH4NO3(s) is added to water at 25 °C, it dissolves spontaneously and the temperature of the solution decreases. This indicates that the factor causing the substance to dissolve is a change in : delta H > 0,i.e.,enthalpy changes and delta S > 0,i.e.,entopy changes</span>
Answer
Atom is the smallest particle of an element.
Hope this helps you!!
Answer:
The equilibrium constant Kp for this reaction is 0.0030
Explanation:
Step 1: Data given
Partial pressure at the equilibrium:
pHCl = 76.9 atm
pO2 = 66.3 atm
pCl2 = 40.7 atm
pH2O = 65.1 atm
Step 2: The balanced equation
4 HCl(g) + O2(g) → 2 Cl2(g) + 2 H2O(g)
Step 3: Calculate the equilibrium constant Kp
Kp = ((pH2O²)*(pCl2²)) /(pO2)*(pHCl^4))
Kp = (65.1²*40.7²) / (66.3*(76.9^4))
Kp = 0.0030
The equilibrium constant Kp for this reaction is 0.0030
Chromium is a metal in nature. So when one chromium is
bonded to another chromium, there is a weak intermolecular forces which helds
them together which we call as “metallic bonding”.
Metallic bonding is the intermolecular force of attraction which
exist between valence electrons and the metal atoms. It is considered as the
sharing of various detached electrons between many positive ions, whereby the
electrons serve as a "glue" which gives the substance a definite
structure.
