Answer:
3.57 g.
Explanation:
- The ratio of cream of tartar (KHC₄H₄O₆) to baking soda (NaHCO₃) in the baking powder is 1:1.
- We need to calculate the number of moles of (8.0 g) of cream of tartar (KHC₄H₄O₆) using the relation:<em> n = mass / molar mass,</em>
mass of cream of tartar (KHC₄H₄O₆) = 8.0 g.
molar mass of cream of tartar (KHC₄H₄O₆) = 188.1772 g/mol.
∴ n of cream of tartar (KHC₄H₄O₆) = mass /molar mass = (8.0 g) / (188.1772 g/mol) = 0.0425 mol.
- Since the mole ratio of the two components is 1:1, the no. of moles of baking soda (NaHCO₃) should be added is 0.0425 mol.
- The quantity of baking soda (NaHCO₃) can be calculated using the relation:
mass = n x molar mass = (0.0425 mol)(84.007 g/mol) = 3.57 g.

Answer:
The correct approach is Option B (Peer Review).
Explanation:
- Rather made reference to someone as a scientific peer-review, it encourages the specialist who has not been essential to the study team to analyze the study objectively and pointed out everyone's mistakes. It serves as major self-regulation for scholars and aims to make the publishing process somewhat credible. Hence, the solution to this issue is Peer Examination.
- Funding organizations rarely have the capabilities to recognize out mistakes, whereas definitive analysis is a method of study that helps to make a definitive statement. The gathering of data is simply a process of scientific study.
Other approaches do not apply to the example mentioned. Although the one mentioned is right.
