Hi, I am not a student but felt this question was at such a basic level it could go here
I understand the concept of radioactive decay and obtaining a ratio of parent to decay product. I feel I am missing something very basic though.
Lets say you are using Uranium-Lead to measure an age. Is all the lead in the sample assumed to be decay product ?
I suppose this is what I get for trying to learn this stuff off the internets

Baking SODA needs an acid to generate co2.
Baking POWDER is a mixture of Baking soda, cream of tartar and only needs water to activate. It does get weaker with age , so you need fairly fresh. Humidity will degrade it faster.
From baking chemistry lemon juice in water is a good cheat for demonstrations, it will activate either.
