Phytoplankton, a specific type of microscopic producer, supplies up to 50% of Earth's oxygen.
Answer: 123 g
Explanation: Q =It = nzF. For Ca^2+ z= 2, t = 5.5 x 3600 s and I = 30.0
And F= 96485 As/mol
Amount of moles is n = It /zF = 3.078 mol , multiply with atomic mass 40.08 g/mol
Answer:
Explanation:
For the reaction: 2X + 3Y = 3Z, the combination of 2.00 moles of X with 2.00
moles of Y produces 1.75 moles of Z
2 mol 2 mol 1.75 mol
2X + 3Y = 3Z
need 2 mol 3 mol to give 3 mol
3 mol Z/3 mol Y= 1 to 1
should get 2 mol Z
1.75/2 =87.5 % yield
Baking powder is primarily used as a leavening agent in baked goods and products. It is a combination of cornstarch, cream of tartar and baking soda. The main observation that suggests that it is a mixture of substances is that fact that it produces a gas which facilitates the rising of the baked goods.
