STatiana [176]3 years ago

8 0

Answer:

8.00 moles.

Explanation:

The ratio of Fe to FeO is 2:2 = 1:1, so 8 moles are produced.

In a certain industrial process involving a heterogeneous catalyst, the volume of the catalyst (in the shape of a sphere) is 10.

mamaluj [8]

Answer:

D

Explanation:

We know that the

reaction catalyzing power of a catalyst ∝ surface area exposed by it

Given

volume V1= 10 cm^3

⇒ $\frac{4}{3} \pi r^3= 10$

hence r= 1.545 cm

also, surface area S1= $4\pi r^2$

now when the sphere is broken down into 8 smaller spheres

S2= 8×4πr'^2

now, equating V1 and V2 ( as the volume must remain same )

$\frac{4}{3}\pi r^3=8\times\frac{4}{3} \pi r'^3$

and solving we get

r'= r/2

therefore, S2= $8\times4\pi\frac{r}{2}^2$

S2= $2\times4\pi r^2$

S2= 2S1

hence the correct answer is

. The second run has twice the surface area.
