Based on your question where there is a concentration of 1 M, the weak acid HN02 is 2% ionized nad the PH of the solution is 1.2. The possibilities that could happen to KNO2(s) if it will dissolved into the solution is that w<span>hen more nitrite is added to the solution, the reaction will shift towards the reactants because of La Châtelier's principle. In doing this, the solution will decrease in hydronium concentration and therefore the pH will increase by some amount.</span>
The Haber Process combines nitrogen from the air with hydrogen to form ammonia. The reaction is reversible and the production of ammonia is exothermic.
N2(g)+H2(g)⇌2NH3(g)
A. What life may have been like before the evoltuon of photosynthesis
Answer:
- <em>If a piece of iron were placed close to this device, the iron nail would move toward the piece of iron.</em>
Explanation:
The description of the built device corresponds to a temporal electromagnet: as long as the battery is connected and supplying the potential difference (voltage) the iron nail will have magnet properties.
Since magnets attract and are attracted to iron, the iron nail and the piece of iron would feel attracted to each other.
The question is confusing because it asks what would happen to a piece of iron if it were placed close to this device, but it should be what happens to the iron nail if a piece of iron were placed close to this device.
Then, assuming the iron nail is free to move it would move toward the piece of iron due to the electromagnetic force.
