Answer:
Some serious diseases like anthrax is also caused in animals by the microbes. Microbes also cause diseases of plants like blights in potatoes, sugarcanes, oranges etc. They also reduce the yield. Microbes grow on food products and render them unfit for consumption.
Explanation:
I believe you are referring zero as the exponent. <span>Any number (except 0) with exponent 0 is defined to mean 1.
</span>
For one thing, there is a rule:
<span> a^m/ a^m = a^m-m = a^0
</span>But (when a is not equal to <span>0),
</span>
a^m/ a^m = 1
Therefore, we must define a^0 as 1.
Most metamorphic processes take place a few kilometers below Earth's surface. Metamorphic processes result due to intense heat and high pressure below the Earth's surface. Also, metamorphism can occur on two scales, contact and regional.
Those are types of water on a pH scale 7.0 and above are alkili water and anything under that is acidic
Answer:
The equilibrium concentration of HCl is 0.01707 M.
Explanation:
Equilibrium constant of the reaction = 
Moles of ammonium chloride = 0.573 mol
Concentration of ammonium chloride = 
Initial: 0.573 0 0
At eq'm: (0.573-x) x x
We are given:
![[NH_4Cl]_{eq}=(0.573-x)](https://tex.z-dn.net/?f=%5BNH_4Cl%5D_%7Beq%7D%3D%280.573-x%29)
![[HCl]_{eq}=x](https://tex.z-dn.net/?f=%5BHCl%5D_%7Beq%7D%3Dx)
![[NH_3]_{eq}=x](https://tex.z-dn.net/?f=%5BNH_3%5D_%7Beq%7D%3Dx)
Calculating for 'x'. we get:
The expression of 
for above reaction follows:
![K_c=\frac{[HCl][NH_3]}{[NH_4Cl]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BHCl%5D%5BNH_3%5D%7D%7B%5BNH_4Cl%5D%7D)
Putting values in above equation, we get:
On solving this quadratic equation we get:
x = 0.01707 M
The equilibrium concentration of HCl is 0.01707 M.
