Answer:
Explanation:
The name of the compound, C₅H₁₂, is pentane. It is a member of the alkane family hence it is saturated (no double or triple bond within it's carbon chain) and SP³ hybridized. It's three structural isomers are shown (drawn) in the attachment below. The three structural isomers are n-pentane, 2-methylbutane and 2,2-dimethylpropane.
Answer:
7.7×10^-6
Explanation:
CoCO3(s)<--------> Co^2+(aq) + CO3^2-(aq) Ksp= 1.0 ×10 ^-10
Co^2+(aq) + 6NH3(aq) <-----------> [Co(NH3)6]^2+. Kf = 7.7×10^4
Overall:
CoCO3(s) + 6NH3(aq) <--------> [Co(NH3)6]^2+(aq) + CO3^2-(aq) Knet= Ksp× Kf
Knet= Ksp× Kf = 1.0 ×10 ^-10 ×7.7×10^4= 7.7×10^-6
The insoluble CoCO3 dissolves in the presence of ammonia because bof the formation of hexamine cobalt II complex ion.
Milk of magnesia helps to neutralize stomach acid because it is a strong base.
Acid: Acids have a sour taste and turn certain dyes red.
It gives off hydrogen ions in water and forms salts by combining with certain metals.
Acids are substances that has pH greater less than 7.
Base: Base turn certain dyes blue.
It takes off hydrogen ions in water and forms salts by combining with certain metals.
It has pH greater than 7.
When acid and base combine, salt is formed.
