Hello!
datos:
Molarity = 
ps: The ionization constant of the nitric acid is strong (100% ionized in water) or completely dissociates in water, so the pH will be:
![pH = - log\:[H_3O^+]](https://tex.z-dn.net/?f=%20pH%20%3D%20-%20log%5C%3A%5BH_3O%5E%2B%5D%20)
![pH = - log\:[2*10^{-4}]](https://tex.z-dn.net/?f=%20pH%20%3D%20-%20log%5C%3A%5B2%2A10%5E%7B-4%7D%5D%20)
Note:. The pH <7, then we have an acidic solution.
I Hope this helps, greetings ... DexteR!
Answer:
<h2>Actin and myosin.</h2>
Explanation:
The cells that allow your bones to move, the movement of thick (myosin) and thin (actin) filaments during contraction
.
During a contraction thick and thin filaments do not shorten but increase their overlap of each other.
Thin filaments slide past thick filaments extending more deeply into the A band.
The I bands and H bands decrease in lenght as Z discs are come closer together
.
Sarcomere represents area between two Z disc, so the sarcomere gets smaller during a contraction
.
Answer:
n=N/Na
n = \frac{8.23 \times {10}^{22} }{6.02 \times {10}^{23} } = 0.1367 \: mol

Answer:
A typical human eye will respond to wavelengths from 390 to 710 nm (in vacuum or air). In terms of frequency this corresponds to a band in the vicinity of 420–790 THz.
