Not in your kitchen, but at the power station - yes (unless it is nuclear or wind powered)

An "electric" stove only uses electric energy inside itself. Now, like the other answerer stated, if you follow the chain to see where the electrical energy in your home, thus to your stove, came from all the way to the power plant, it may be chemical if it is a coal, gas or nuclear plant. A wind or solar or hydro plant does not use chemical reactions to create the electrical current.

Well, it kind of depends. The electric stove itself is not using any chemical energy -- assuming that the source of the power is not chemical in nature.
The food itself may be undergoing reactions -- typical for food are the Maillard reaction (responsible for browning and flavors), Caramelization, and the denaturing of proteins (egg whites hardening is a good example of this).
Those types of reactions may involve a transition from a higher to a lower energy state, which would be a use of chemical energy. I'll leave it to you to sort out the specifics :-D.

If the power plant generates electricity by a chemical reaction (gas, coal oil) - then "yes".
If power plant in nuclear - then "no". Nuclear is not a chemical reaction, it's a nuclear reaction - fortunate really, because otherwise nuclear-power-plant would be a misnomer
