Elan Coil [88]
<h3><u>Answer;</u></h3>

NH3/NH4+

<h3><u>Explanation;</u></h3>

From the equation;

NH3(aq)+HNO3(aq)→NH4+(aq)+NO3−(aq)  

NH3 is the base; while NH4+ is the conjugate acid  

HNO3 is the acid; while NO3- is the conjugate base  

  • The conjugate base of a Brønsted-Lowry acid is species that is formed after an acid donates a proton while the conjugate acid of a Brønsted-Lowry base is the species formed after a base accepts a proton.

xxMikexx [17]

Answer:

0.67mol/Kg

Explanation:

The following were obtained from the question:

Mole of solute = 0.50mol

Mass of solvent = 750g = 750/1000 = 0.75Kg

Molality =?

Molality = mole of solute /mass of solvent

Molality = 0.5/0.75

Molality = 0.67mol/Kg

Changes of state are a result of a change in the______of the matter.
jasenka [17]

Answer: -

Kinetic energy.

Explanation: -

Solids have the least kinetic energy and the highest intermolecular force of attraction among the three states of matter.

When heat energy is supplied to the solid, the kinetic energy of the solid particles increases. At some point, the kinetic energy becomes comparable to the intermolecular force of attraction. At that point solids change into liquids.

When further heat energy is given, at certain point the kinetic energy becomes far greater than the intermolecular forces of attraction. At that point it becomes gas.
