Hello!
The substance that is acting as the Br<span>ønsted-Lowry Acid is H</span>₂O
This is the chemical reaction:
H₂O + NH₃ → NH₄⁺ + OH⁻
In the Brønsted-Lowry Acid Concept, an Acid is a substance which donates a proton, and a Base is a substance which accepts protons. To know which compounds are acids and which are bases in this theory, we need to look at the proton movements. H₂O (The Acid) is donating a proton to NH₃ (The base), to produce NH₄⁺ (An acid) and OH⁻ (A base). Water is not commonly seen as an acid, but in this reaction, it is a Brønsted-Lowry Acid.
Have a nice day!
Explanation:
By placing the jar under hot water, metal lid molecules expanded from heat which caused it loosen up. However, there can be a possibility where the jar lid was stuck because of the stickiness of the pickle juice which later got washed off or melted after placing the jar under hot water.
Answer:
option D = particle size
Explanation:
The particles size of sand is greater then the pore size of filter paper and can not passed through the filter paper and easily filter out. While salt present in sea water are easily pass through the pore of filter paper.
The solution of sand and water is suspension.
Properties of suspension:
The particle size in suspension is greater than 1000 nm.
These particles can seen through naked eye.
It is heterogeneous.
The particles in suspension can be separated through the filtration.
