Answer : The angular acceleration is
Solution : Given,
The given angular velocity equation is,
At t = 0,
At t = t,
Angular acceleration : It is defined as the rate of change of angular velocity with respect to time.
Formula used for angular acceleration :
where,
= angular acceleration
= angular velocity at time 't'
= angular velocity at time '0'
t = time
Now put all the given values in this formula, we get the angular acceleration.
Therefore, the angular acceleration is
Answer:
6.0 x 10^-1 g Fe
Explanation:
I might be in the wrong but hear me out:
Convert 0.85 g to mols of Fe2O3.
0.85 g x 1 mol/159.69=0.0053 mols Fe2O3.
Get moles of Fe (iron metal).
0.0053 mols Fe2O3 x 2 mol Fe/ 1 mol Fe2O3
= 1.0 x 10^-2 mols Fe
Convert moles to grams of Fe.
1.0 x 10^-2 mols of Fe x 55.85 grams Fe/ 1 mol Fe
= 6.0 x 10^-1
There should be only one sig fig. Hoped this helped.

Answer:
<h3>the equilibrium constant of the decomposition of hydrogen bromide is 0.084</h3>
Explanation:
Amount of HBr dissociated
2HBr(g) ⇆ H2(g) + Br2(g)
Initial Changes 2.15 0 0 (mol)
- 0.789 + 0.395 + 0.395 (mol)
At equilibrium 1.361 0.395 0.395 (mole)
Concentration 1.361 / 1 0.395 / 1 0.395 / 1
at equilibrium (mole/L)
<h3>Therefore, the equilibrium constant of the decomposition of hydrogen bromide is 0.084</h3>
I'm not one hundred percent sure but wouldn't group selection be most harmful to the ecosystem because they cut down a group of trees all at once instead of one by one.
