Answer: Option (d) is the correct answer.
Explanation:
According to Bronsted-Lowry an acid is defined as the specie which is able to donate hydrogen ions when dissolved in water.
For example, 
On the other hand, bases are the species which are able to donate hydroxide ions when dissolved in water.
For example, 
Thus, we can conclude that a definition of an acid is that it donates H ions when dissolved in water.
The Heisenberg Uncertainty Principle states that it is impossible to determine simultaneously both the position and the velocity of a particle. The detection of an electron, for example, would be made by way of its interaction with photons of light.
NaCI has a greater % of sodium because the Chloride ion is closer in size to Na ion than Bromide ion is to Na ion. Therefore the NaCl lattice is more neatly and closely packed, leading to higher melting point.
Some potential energy was converted into thermal energy due to friction. The acceleration due to gravity became smaller as the box slid down the ramp.
