The larger the piece the longer it will take to break down. This is because it has more mass that needs to be broken down.
Answer:
No, in science their meanings are not the same as their everyday meanings.
Explanation:
In Science, Precision and Accuracy are defined as,
Accuracy:
Accuracy is the value which is closest to the known or standard value.
Precision:
While, Precision is the value of closeness of two measured values to each other.
Example:
Let suppose in Chemistry Lab you weight an object as 50 g. While the actual weight of that object is 30 g. It means your reading is not accurate.
On second measurement you find that the object weight is 31 g. This time your reading is not precise.
(6.0×10^4) = 60,000
(3.1×10^-1) = 0.31
60,000 × 0.31 = 18,600
11.30 i believe is the answer
Answer: The equilibrium constant for 
is 1.35
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
For the given chemical reaction:
The expression for is written as:
![K_c=\frac{[PX_5]^1}{[PX_3]^1[X_2]^1}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BPX_5%5D%5E1%7D%7B%5BPX_3%5D%5E1%5BX_2%5D%5E1%7D)
![0.74=\frac{[PX_5]^1}{[PX_3]^1[X_2]^1}](https://tex.z-dn.net/?f=0.74%3D%5Cfrac%7B%5BPX_5%5D%5E1%7D%7B%5BPX_3%5D%5E1%5BX_2%5D%5E1%7D)
For the reverse chemical reaction:
The expression for 
is written as:
![K_c'=\frac{[PX_3]^1[X_2]^1}{[PX_5]^1}](https://tex.z-dn.net/?f=K_c%27%3D%5Cfrac%7B%5BPX_3%5D%5E1%5BX_2%5D%5E1%7D%7B%5BPX_5%5D%5E1%7D)
The equilibrium constant for is 1.35
