Answer:
4.31 × 10²
Explanation:
Equation of the reaction;
⇌ 
The ICE Table is shown as follows:
⇌
Initial 3.10 2.50 0
Change - x -x + 2x
Equilibrium (3.10 - x) 0.0800 2x
From ;
We can see that 2.50 - x = 0.0800
So; we can solve for x;
x = 2.50 - 0.0800
x = 2.42
which = (3.10 -x) will be :
= 3.10 - 2.42
= 0.68
= 2x
= 2 (2.42)
= 4.84
![K_c = \frac{[HI]^2}{[H_2][I_2]}](https://tex.z-dn.net/?f=K_c%20%3D%20%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BH_2%5D%5BI_2%5D%7D)
430.62
≅ 431
= 4.31 × 10²
I’m not sure if there was important information in the question before this one, but the answer based on the info I have is B.
The density of water is 1kg/L. Since the density of the block is less, it will float.
It is the first one because haven't you ever noticed when you hold a mirror a certain way the light can reflect a light up another surface? so, therefore, the answer that makes the most sense would be the first. :)
Answer:
(C) Decomposition reaction
Explanation:
A decomposition reaction is a chemical reaction in which a single compound breaks down into two or more compounds or elements.
<u>in this example </u>
- 2KClO₃(s) ->2KCl (s) + 3O₂ (g)
Potassium chlorate (KClO₃) decomposed to two smaller compounds KCl and O₂ gas.
So, the right choice is (C) Decomposition reaction
Its a Generator
It generates an electrical current using a battery.
A motor generates a mechanical current that you have to physically generate yourself.
Hope this helps! :)
