Answer:
When carbon dioxide reacts with water carbonic acid is formed, from which hydrogen ions dissociate increasing the acidity of the systemCarbon dioxide emissions to the atmosphere can therefore increase the acidity of land, sea and air
Explanation:
Answer:
2.26 × 10²⁴ atoms of Fe
Explanation:
To calculate the amount of atoms of a substance using the amount of moles, we must multiply by Avagadro's number.
(3.75mol) × (6.02 × 10²³) = 2.26 × 10²⁴ atoms of Fe
The answer should be B - Nitrogen Dioxide.
Answer:
you sure it is the right sign your using
Answer:
This question appears incomplete
Explanation:
However, it should be noted that addition of soluble salts generally lowers the freezing point of water hence after the addition, water will no longer freeze at 0°C but lower.
Soluble salts tend to form more ions in water, it is these ions that are responsible for interfering with the hydrogen bonds hence lowering the freezing. Thus, (since each bag are of the same weight) <u>the bag that contains the salt that ionizes more in water will lower the freezing point by the greatest amount</u>.
NOTE: Different weight of the salts could lead to more ions been formed in the water by some salts as against the other.
