Answer:
[H+] = 1.66 x 
Explanation:
To find the [H+] concentration of a solution, we can use the formula:
![[H+] = 10^{-pH}](https://tex.z-dn.net/?f=%5BH%2B%5D%20%3D%2010%5E%7B-pH%7D)
Let's plug in the pH.
![[H+] = 10^{-3.78}](https://tex.z-dn.net/?f=%5BH%2B%5D%20%3D%2010%5E%7B-3.78%7D)
Evaluate the exponent.
[H+] = 1.66 x 
Hope this helps!
Answer:
It is like an arch because it bends horizontal just like we do and the legs of the arch support the stone like our feet and legs support the weight of us.
Explanation:
Newton’s first law states that motion stays the same throughout unless changed such as a football being placed on the ground and not moving it stays at rest and the football being thrown stays in motion unless changed by direction.
