Magnetizing steel is a physical change, not a chemical change.
When a crop of wheat grows, new organic matter is created by the process of photosynthesis, which converts light energy into energy stored in chemical bonds within plant tissue. ... New compounds and structures are synthesized, cells divide, and the plant grows in size over time

Answer:
A rule of thumb is that 1.5 lbs. of baking soda per 10,000 gallons of water will raise alkalinity by about 10 ppm. If your pool's pH is tested below 7.2, add 3-4 pounds of baking soda. If you're new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount.
Answer:
The egg white will represent the outer layer which is the we are located on!
Explanation:
Answer: ![1.67\times 10^{-3}](https://tex.z-dn.net/?f=1.67%5Ctimes%2010%5E%7B-3%7D)
Explanation:
![ClCH_2COOH\rightarrow ClCH_2COO^-+H^+](https://tex.z-dn.net/?f=ClCH_2COOH%5Crightarrow%20ClCH_2COO%5E-%2BH%5E%2B)
cM 0 0
So dissociation constant will be:
![K_a=\frac{(c\alpha)^{2}}{c-c\alpha}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%28c%5Calpha%29%5E%7B2%7D%7D%7Bc-c%5Calpha%7D)
Given: c = 0.15 M
pH = 1.86
= ?
Putting in the values we get:
Also ![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
![1.86=-log[H^+]](https://tex.z-dn.net/?f=1.86%3D-log%5BH%5E%2B%5D)
![[H^+]=0.01](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.01)
![[H^+]=c\times \alpha](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3Dc%5Ctimes%20%5Calpha)
![0.01=0.15\times \alpha](https://tex.z-dn.net/?f=0.01%3D0.15%5Ctimes%20%5Calpha)
![\alpha=0.06](https://tex.z-dn.net/?f=%5Calpha%3D0.06)
As ![[H^+]=[ClCH_2COO^-]=0.01](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D%5BClCH_2COO%5E-%5D%3D0.01)
![K_a=\frac{(0.01)^2}{(0.15-0.15\times 0.06)}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%280.01%29%5E2%7D%7B%280.15-0.15%5Ctimes%200.06%29%7D)
![K_a=1.67\times 10^{-3]](https://tex.z-dn.net/?f=K_a%3D1.67%5Ctimes%2010%5E%7B-3%5D)
Thus the vale of
for the acid is ![1.67\times 10^{-3}](https://tex.z-dn.net/?f=1.67%5Ctimes%2010%5E%7B-3%7D)
