Answer:
The water at 38 °C has faster-moving molecules than the sample at 295 K.
Explanation:
Converting the temperature, 295 K from Kelvin to Celsius:
295 - 273 = 22°C
⇒The boiling point of water is 100°C and its melting point 0°C
⇒When we compare water at those 2 different temperatures ( 22°C and 38°C) we can say that water is in liquid form at both these temperatures as both of them are quite below the boiling temperature and above the melting temperature.
⇒The difference in temperature between water at the 2 given temperatures = 38°C - 22°C = 16°C
Water at 38°C is at a higher temperature and so is warmer than water at a lower temperature of 22°C.
At the atomic scale, the kinetic energy of atoms and molecules is sometimes referred to as heat energy. Kinetic energy is also related to the concept of temperature. Temperature is defined as the measure of the average speed of atoms and molecules. The higher the temperature, the faster these particles of matter move.
The equation of the neutralization reaction is:
HOC(CO₂H)(CH₂CO₂H)₂ + Na₂CO₃ ----> HOC(CO₂Na)(CH₂CO₂Na)₂ + H₂O
<h3>What is the acid in lemon juice?</h3>
The main acid in lemon juice is citric acid.
Citric acid is a tricarboxylic acid and will react with baking soda to form a salt and water.
The equation of the neutralization reaction is shown below:
HOC(CO₂H)(CH₂CO₂H)₂ + Na₂CO₃ ----> HOC(CO₂Na)(CH₂CO₂Na)₂ + H₂O
In conclusion, the neutralization of citric acid in lemon juice produces a salt and water.

The advantage of using an orbital notation is that it shows the electron distribution in shells.
<span>Dot structures only show the valence electrons of an atom which are the electrons found at the outermost shell. The orbital notation gives a more detailed depiction of the electrons in each shell. This is most advantageous for atoms that have special cases. </span>
<span>Some examples of atoms that have special electronic configurations are copper and chromium. For example, copper is more stable when the 3d subshell is completely filled. This leaves the 4s subshell with only 1 electron. Chromium is also more stable when its s and d subshells are only half full. The orbital notation depicts these special cases, whereas the dot structure does not.</span>
