Difference Between baking soda and baking powder

Baking soda is sodium bicarbonate, which requires acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid. It only needs a liquid to become activated. Substituting one for the other is possible with careful adjustments. Baking soda is strong. In fact, it is about 3-4x stronger than baking powder. More baking soda in a recipe doesn't necessarily mean more lift.

Explanation:

Explanation:

baking soda contains one ingredient, sodium bicarbonate. however, baking powder contains sodium bicarbonate , monocalcium phosphate and either sodium acid prophetess or sodium aluminum sulfate

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
