A melting point of a substance is a point at which the sample or substance start converting in liquid. For most substances, melting and freezing points are approximately equal. For example, the melting point and freezing point of mercury is 234.32 kelvins (−38.83 °C or −37.89 °F). Hope this helped!! :)
Answer: ![HNO_3(aq)+H_2O(l)\rightarrow NO_3^-(aq)+H_3O^+(aq)](https://tex.z-dn.net/?f=HNO_3%28aq%29%2BH_2O%28l%29%5Crightarrow%20NO_3%5E-%28aq%29%2BH_3O%5E%2B%28aq%29)
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
As
is a stronger acid than water , it will lose
ions and water will gain
ions.
The balanced chemical reaction will be :
![HNO_3(aq)+H_2O(l)\rightarrow NO_3^-(aq)+H_3O^+(aq)](https://tex.z-dn.net/?f=HNO_3%28aq%29%2BH_2O%28l%29%5Crightarrow%20NO_3%5E-%28aq%29%2BH_3O%5E%2B%28aq%29)
where (aq) = aqueous
(l) = liquid
Answer:
B)
. six electrons in the triple bond of diatomic nitrogen
Explanation:
The three line in this Lewis dot structure represents the six electrons in the triple bond of diatomic nitrogen.
Nitrogen is made up of 7 electrons with 5 valence ones.
A lewis structure is made up of the symbol of the element surrounded by dot to represent the valence electrons.
In this nitrogen molecule, both species share 6 electrons. This makes each nitrogen atom isoelectronic with neon.
Be careful on this one! Mass is always conserved, based on the law of conservation of mass. Since their was a change in state, we went from a solid to a gas, so, the weight would be lighter, not the mass.
Same amount of mass.
