Answer:
The answer is 1.63 × 1024 atoms Fe
Explanation:
I'm assuming you need to know the percentage yield of the reaction
To calculate the percentage yield = (actual yield x 100%) / predicted yield
actual yield is 56,9 g
predicted yield is 36,6g ( is the amount that's expected if nothing had got lost)
(56,9 x100)/36,6=
= 155%
I believe the scientific method
Answer:
pH= 1.70
Explanation:
I 4.988 0 0
C -x +x +x
E 4.988 -x x x
8.0 x 10^-5 = X^2/ 4.988 - x
(since the X value is so small, round 4.988-x to 4.988 because X is close to zero)
8.0 x 10^-5 = x^2/4.988
x4.988 x4.988
4.0 x 10^-4 = x^2
x = .0199
pH=-log[.0199] = 1.70
