Hmmmm not sure I’ll tell u when I know
Answer:
4.09 × 10⁻² g
Solution:
As we know that,
1 mol of Fe₂O₃ is equal to = 159.69 g
So,
2.56 × 10⁻⁴ mol will be equal to = X g
Solving for X,
X = (159.69 g × 2.56 × 10⁻⁴ mol) ÷ 1 mol
X = 0.04088 g
Or,
X = 0.049 g
Or,
X = 4.09 × 10⁻² g
Answer:
Every mole contains 6.022 x 10^23 atoms regardless of what type of moelcules it is (Gold, Silver). So the anwer is 1.54 times 6.022 x 10^2
Answer: A
Explanation:in learned this last year:)
The phenomenon known as "salting-out" occurs at very high ionic strengths, when protein solubility declines as ionic strength rises. As a result, salting out may be used to segregate proteins according to how soluble they are in salt solutions.
Because large levels of sodium chloride disturb the bonds and structure of the active site, the rate of enzyme activity will gradually decrease as the concentration of sodium chloride rises. As a result, some of the active sites get denaturized and the starch loses its ability to attach to them. As more enzymes get denatured and eventually cease to function, enzyme activity will steadily wane.
