Answer:

E = 3.81×10 ⁻²¹ J

Explanation:

Given data:

Frequency of photon = 5.75 ×10¹² Hz

Plancks constant = 6.626 ×10⁻³⁴ Js

Energy of photon = ?

Solution:

E = h×f

E = 6.626 ×10⁻³⁴ Js ×  5.75 ×10¹² s⁻¹

E = 38.1×10 ⁻²² J

E = 3.81×10 ⁻²¹ J

What is the mass of 7.675 x 1023 atoms C? Answer in units of g.
nalin [4]

Answer: 15.3 grams C

Explanation:  1 mole is 6.02x10^23 atoms.  We can find the moles of C in 7.675 x 10^23 atoms of C by dividing:

(7.675 x 10^23 atoms C)/(6.02x10^23 atoms C/mole) = 1.275 moles C

The molar mass of carbon is 12g/mole.  So the mass of 7.675 x 10^23 atoms is (1.275 moles C)*(12 g/mole C) = 15.3 grams.

The following reaction is found to be at equilibrium at 25 celcius: 2SO3--->O2 + 2SO2 + 198kJ/mol. If the value for Kc at 25
kondaur [170]

Answer:

D.) Products are weakly favored

Explanation:

For the reaction:

2SO₃ ⇄ O₂ + 2SO₂ + 198kJ/mol

The kc is defined as:

kc = [O₂] [SO₂]² / [SO₃]²

As the kc is 8,1:

8,1 [SO₃]² =  [O₂] [SO₂]²

The products are favored 8,1 times. This is a weakly favored because the usual kc are in the order of 1x10⁴. Thus, right answer is:

D.) Products are weakly favored

I hope it helps!
