Answer:
![Ka=\frac{[H^+][NO_2^-]}{[HNO_2]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%2B%5D%5BNO_2%5E-%5D%7D%7B%5BHNO_2%5D%7D)
Explanation:
The reaction
The reaction of nitrous acid with water is a dissociation reaction of an acid:
The Ka equation
Answer:
Anemometers measure wind speed and wind vanes measure wind direction. A typical wind vane has a pointer in front and fins in back. When the wind is blowing, the wind vane points into the wind.Barometers, manometers and anemometers are all scientific instruments. Scientists use barometers and manometers to measure atmospheric pressure, while anemometers measure wind speed.
Explanation:
Answer:
0.1 and 0.2.
Explanation:
The person's blood is 0.1 decreases and become more acidic if it has a pH of 7.3 compared to its preferred 7.4 while on the other hand, the person's blood is 0.2 increases and become more alkaline it has a pH of 7.6rather than its preferred 7.4. There is 0.1 decrease and 0.2 increase in the pH of the person's blood. If the pH decreases so it means it moves towards more acidic whereas, if the pH increases there is moves towards alkaline.
It is 292.5 m because you do 4.5 hours times 65. (please give me brainliest)
