This is because of the increasing number of protons in the nucleus, resulting in a stronger attraction of the electrons with the nucleus.
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.
Iron phosphate when in acidic solution would dissociate into ions namely the iron ions and the phosphate ions. Furthermore, the phosphate ion would react to the hydronium ions forming HPO4^2-. To determine the net ionic equation we do as follows:
FePO4 <---------> Fe3+ + (PO4)3-
(PO4)3- + H3O+ <--------------> HPO4^2- + H2O
Adding the two equations would yield to:
FePO4(s) + H3O+(aq) ⇌ Fe^3+(aq) + HPO4^2−(aq) + H2O(l)
