Answer:

c=3\times 10^{17}\ nm/s

Explanation:

The speed of light is 3\times 10^8\ m/s. It is required to convert it into nm/s.

The relation between nm and m is as follows :

1\ nm=10^{-9}\ m\\\\1\ m=10^9\ nm

So,

c=3\times 10^8\ m/s \\\\c=3\times 10^8\times 10^9\ nm/s\\\\c=3\times 10^{17}\ nm/s

So, the speed of light is 3\times 10^{17}\ nm/s.

dolphi86 [110]
I believe it is useful as it shows how electrons are distributed in the shells (energy levels) of an iron atom. An atom is the smallest particle of an element that can take part in a chemical reaction. It contains the nucleus and the shells (energy levels). the nucleus contains protons and neutrons while the shells contain electrons.

How many moles are in 4.3 x 1022 molecules of H 3 PO 4 ?
Anon25 [30]

Answer:

0.071 mole

Explanation:

As discovered from Avogadro's hypothesis, 1 mole of any substance contains 6.02x10^23 molecules.

This simply means that 1 mole of H3PO4 also contains 6.02x10^23 molecules.

If 1 mole H3PO4 contains 6.02x10^23 molecules,

Then, xmol of H3PO4 will contain 4.3x10^22 molecules i.e

Xmol of H3PO4 = 4.3x10^22/6.02x10^23 = 0.071 mole

From the calculations made above, 4.3x10^22 molecules of H3PO4 have 0.071 mole of H3PO4

Propane can be turned into hydrogen by the two-step reforming process. In the first step, propane and water react to form carbon
Vsevolod [243]

Answer:

The net chemical equation is: 6 H2O(g) + C3H8(g) → 10 H2(g) + 3 CO2(g)

Explanation:

First equation:

The reactants propane and water  react to form the products CO and H2

C3H8(g) + 3H2O(g) → 3CO(g) + 7H2(g)

Second equation:

The products CO and H2 will react

CO(g) + H2O(g) → H2(g) + CO2(g)

We should multiply the equation by 3 (to equal the products of the first equation)

3CO(g) + 3H2O(g) → 3H2(g) + 3CO2(g)

Add the second to the first equation:

C3H8(g) + 3 H2O(g) + 3 CO(g) + 3 H2O(g) → 3 H2(g) + 3CO2(g) + 3 CO(g) + 7 H2(g)

The net chemical equation is: 6 H2O(g) + C3H8(g) → 10 H2(g) + 3 CO2(g)

finlep [7]

Answer:

11690J

Explanation:

Use formula Q = mL

where:

Q = Energy (J)

m = Mass (g)

L = Latent heat of fusion for water (J/g) = 344J/g

Therefore:

Q = 35.0 x 344

Q = 11690J
