If you take a pinch of the baking powder and put it in water, it should fizzle. If it does not fizzle, it is no longer fresh.
To make chocolate, you take the cocoa pod and take the cocoa beans out of it, Then you roast them. Then you crush them, and VOILA!!! YA GET POWDER
Okay, let's take the basics: There is no such thing as "copper sulfate baking powder", as it would be poisonous. I can think of no way to relate elemental nickel to the fictitious "copper sulfate baking powder".
It doesn't take any time: instantaneous!
Take the dog to the vet ASAP, cocoa is toxic,
Baking powder is Sodium Bicarbonate a polar compound that is particularly amenable to water (a polar solvent). So Baking powder will dissolve faster than a non-polar powder like Talcum powder. Also baking power is very finely ground and will present a large surface area to the water which hastens dissolving. Salt in comparison although a strongly polar compound is course ground and will take longer to dissolve.
One is not better than the other. Baking soda will make the cookies crisper, and make them rise more. Baking powder will make them softer. Take your pick. I baked cookies with baking soda and it made the cookies look more like sticky bread than cookies. You absolutely can NOT use baking soda at all. Baking powder is for cookies, baking soda is for stuff you want to rise (like bread). The answer above is false.
No, they are entirely different chemical compounds.
to kill a sponge u take baking powder and vinegar and mix it in to the sponge then take knife and chop it up
Self-rising flour consists of flour, baking powder, and salt. So the flour here is ordinary flour to which you add bicarbonate of soda and salt. Baking powder is baking soda, an acid salt, and cornstarch (the effect is to create carbon dioxide when it is placed in a solution). To make self-rising flour, take one cup of flour and add one and a half (1 1/2) teaspoons of baking powder and 1/2 teaspoon of salt.
take a bottle and add some vinegar to it. Then add some baking powder and red flavour to the vinegar and shake it well.
Yes. They can. The clues of a chemical reaction are production of a gas, change in temperature, color change, production of a precipitate. If you take either baking soda or baking powder, and you add them to vinegar they both form bubbles in a chemical reaction.
