In the reaction Sn(s) + 2H+(aq) → Sn2+ (aq) + H2(g)
from this reaction, we get that Sn loses from 0 to 2 electrons so it's oxidized So it is the reducing agent.
and H gains from 0 to 1 electrons so, it's reduced so ∴ it is the oxidizing agent
Answer:
When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. As the current travels through the wires and the filament, the filament heats up to the point where it begins to emit photons, which are small packets of visible light.

Answer:
Paris climate agreement of 2015
Explanation:
In the year 2015, global leaders seeking to join forces to combat the ever increasing emissions of green house gases which is having a bad influence on our prevailing world climate met in Paris in 2015, although the treaty became effective in the year 2016.
There are 195 signatories to the treaty. The Paris Agreement's long-term temperature goal is to keep the increase in global average temperature to well below 2 °C above pre-industrial levels; and to pursue efforts to limit the increase to 1.5 °C, recognizing that this would substantially reduce the risks and impacts of climate change.
I think the correct answer is decrease in temperature
I feel like that’s the right one
Answer : The pH of the resulting solution is 4.6
Explanation : Given,
Activity coefficient for acetic acid = 1.000
Activity coefficient for acetate ion = 0.775
Ionic strength = 0.10 M
To calculate the pH of resulting solution we are using Henderson Hesselbach equation :
![pH=pK_a+\log \frac{[Salt]}{[Acid]}](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%20%5Cfrac%7B%5BSalt%5D%7D%7B%5BAcid%5D%7D)
Now put all the given values in this expression, we get:
Thus, the pH of the resulting solution is 4.6
