Answer:
3. Gas, solid
Explanation:
Deposition is the process of gas changing directly to a solid. It skips the liquid state.
Answer:
0.89821 atm
Explanation:
Psi and atm are units of pressure.
Psi stands for pound force per square inch.
While atm stands for atmosphere.
In order to convert the psi to atm we would divide the given value 14.696.
Given value = 13.2 psi
In atm:
13.2 / 14.696 = 0.89821 atm

The two s Orbital electrons and one d orbital electron, are the electrons that are lost by an atom of Iron when it forms the Fe3 + ion.
<u>Given:</u>
H2(g) + Cl2 (g) → 2HCl (g)
<u>To determine:</u>
The enthalpy of the reaction and whether it is endo or exothermic
<u>Explanation:</u>
Enthalpy of a reaction is given by the difference between the enthalpy of formation of reactants and products
ΔH = ∑nHf (products) - ∑nHf (reactants)
= [2Hf(HCl)] - [Hf(H2) + Hf(Cl2)] = 2 (-92.3) kJ = - 184.6 kJ
Since the reaction enthalpy is negative, the reaction is exothermic
<u>Ans:</u> The enthalpy of reaction is -184. kJ and the reaction is exothermic
