Explanation:
a=5
b=9
c=3
d=4
that's the correct brainliest answer
3+2=5
+ + +
1 +3 =4
= = =
4+5=9
I think it is decomposition
Answer:
The choice of the answer is fourth option that is -61 degrees.
Therefore the temperature drop is -61°Centigrade.
Explanation:
Given:
The temperature in a town started out at 55 degrees
Start temperature = 55°Centigrade. (Initial temperature)
End of the Day = -6°Centigrade. (Final temperature)
To Find:
How far did the temperature drop?
Solution:
We will have,

Substituting the above values in it we get

Therefore the temperature drop is -61°Centigrade.
The correct answer to this question is letter "B) 8.4 × 10-4 M."
2CO+O2<->2CO2
-x -x +x
It started as 2CO2 so +x, then it decomposed into 2CO and O2, so-x
2CO-oxidized, O2-Oxidized, 2CO2-reduced
the easiest way is to look at the equation, so if we have some reactant and no product
A<->2C+D
-x +2x +x
so if we had product concentration, and no reactant concentration
3A<-> C+D
+3x -x-x
