Help!! How many moles of CaCO3 are needed to get 2.35 moles of CaO? What would be my reasoning and evidence?

Fudgin [204]

Equation

CaCO3 ===> CaO + O2

Solution

If you start with this equation, then the balance numbers (molar ratios) are

1 for the CaCO3
1 for the CaO
1 for the O2

If you want 2.35 moles of CaO then you are going to have to start out with 2.35 moles of CaCO3

2-Ethoxy-2,3-dimethylbutane reacts with concentrated aqueous HI to form two initial organic products (A and B). Further reaction

Leno4ka [110]

Answer:

A = 2-iodo-2,3-dimethylbutane

B = Ethanol

C = Iodoethane (also called ethyl-iodide)

Explanation:

2-Ethoxy-2,3-dimethylbutane reacts with conc. HI to cleave the oxy-functional group.

On one end, ethanol is formed and on the other hand, 2-iodo-2,3-dimethylbutane is formed.

But ethanol reacts further with conc HI to give iodoethane.

Therefore,

A = 2-iodo-2,3-dimethylbutane

B = Ethanol

C = Iodoethane (also called ethyl-iodide)

This is all shown in the attached image.

Hope this Helps!!!
