Answer : The number of moles of HCl neutralize is, 0.00824 moles.
Explanation :
The given balanced chemical reaction is:
First we have to calculate the moles of
Molar mass of = 144 g/mol
Now we have to calculate the moles of HCl.
From the balanced chemical reaction we conclude that,
As, 1 mole of react with 4 moles of HCl
So, 0.00206 mole of react with
moles of HCl
Thus, the number of moles of HCl neutralize is, 0.00824 moles.
Answer:
Kinetic; attraction; attraction.
Explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where, K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.
In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.
Hence, as the temperature of a substance increases, the average kinetic energy of the particles also increases, and movement overcomes forces of attraction more easily. As temperature decreases particles move more slowly and the attraction-forces between particles dominate.
In conclusion, when a substance or an object is heated, a phase change starts to occur only when the average kinetic energy of its particles is great enough to overcome the force of attraction between its particles.
