Answer:
Below
Explanation:
The balanced equation for h202 = h20 + 02 is:
2H2O2 = 2H20 + O2
The coefficients would be 2
The balanced equation for Na + I2 = NaI is:
2Na + I2 = 2NAI
The coefficients would be 2
Hope this helps! :)
Answer:
5000 and 
indicate that there is more B than A at equilibrium
Explanation:
For the given reaction: ![K=\frac{[B]}{[A]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BB%5D%7D%7B%5BA%5D%7D)
where [B] and [A] represents equilibrium concentration B and A respectively. K represents equilibrium constant
More B than A at equilibrium means, [B] > [A]
So, ![K=\frac{[B]}{[A]}>1](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BB%5D%7D%7B%5BA%5D%7D%3E1)
As, both 5000 and are greater than 1 therefore these two K values indicate that there is more B than A at equilibrium

The thermal energy (Q) needed : = 1882.8 J
<h3>Further explanation</h3>
Given
15g water from 25 °C to 50 °C
Required
The thermal energy (Q)
Solution
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
Input the value :
Q = 15 g x 4.184 J/g°C x (50 °C- 20 °C)
Q = 1882.8 J
