Answer:
26.5°C
Explanation:
Heat added is the product of mass, specific heat capacity, and change in temperature.
q = mC(T − T₀)
25.7 cal = (18.4 g) (0.215 cal/g/°C) (T − 20.0°C)
T = 26.5°C
The Ksp of AgOH will be "1.98×10^-8"
According to the question,
The chemical reaction is:
AgOH + HCl → AgCL(s) + H2O
As we know the relation,
C₁V₁ = C2V2
(AgOH) (HCI)
By substituting the values, we get
C₁ x 250 mL = 0.0136 × 2.60 mL
C1 = 0.0136×2.60/250 = 0.000141
Now,
AgOH = Ag + OH
AgOH = Ag + OH (s) (s)
hence, The Ksp will be: (s)^2 = (0.000141)² =
1.98 x 10^-8
The Ksp of AgOH will be 1.98×10^-8

Answer:
Cis and trans isomers
Explanation:
Existence of double bond in carbon rich compound confirms the presence of geometrical isomer in the compound. The compound showing geometrical isomer exists as cis and trans isomers.
Substituents or functional group around double bond decides that the compound will be cis or trans.
If functional group or bigger substituents are present on the same side of the double bond, the compound will be cis.
If functional group or bigger substituents are present on the opposite of the double bond, the compound will be trans.
