actor Atoms Molecules
Definition Most fundamental and smallest part that can exist of an element. Two or more atoms chemically bonded together.
Example Oxygen – O
Phosphorus – P
Sulphur – S
Hydrogen – H Oxygen – O2
Phosphorus – P4
Sulphur – S8
Water – H2O
Structure The smallest particle with properties of an element. Combination of two or more atoms.
Stability An atom may not always be stable in nature due to the presence of electrons in the outer shells. Molecules are formed to attain stability.
Constituent Elements Protons, Electrons & Neutrons Two or more atoms of the same or different elements
Reactivity Except for the noble elements, atoms of all elements showcase a certain level of reactivity. Compared to a molecule, the level of reactivity is less than some valence points are filled by electrons of combined elements.
Answer:
The temperature of the mixture is 60°C
Explanation:
We can write the energy of water as follows:
E = m×C×T
<em>Where E is energy in Joules, m is mass of water, C is specific heat of water = 4.184J/g°C and T is temperature</em>
<em />
Replacing fot both samples:
E = 20g×4.184J/g°C×30°C
E = 2510.4J
E = 40g×4.184J/g°C×75°C
E = 12552J
The total energy of the mixture is 12552J + 2510.4J = 15062.4J
Mass = 60g:
15062.4J = 60g×4.184J/g°C×T
60°C = T
<h3>The temperature of the mixture is 60°C</h3>
