The careers in chemistry should be closely related to working with chemical substances and the methods involved in experiments. Thus, the answers are finds practical applications information chemist and<span> market research R&D.</span>
A force exerted by the machine is called a Mechanical force.
Answer:
Temperature will revert to room temperature after the substance reacts fully. Heat energy flows between the chemical bonds of the added substance and water to the surroundings (elsewhere in the water, the beaker, a student's hand that touches the beaker).
Explanation:
Answer:
The melting points of the second series of transition elements are electrons are entering to the type of orbital.
Explanation:
Transition elements have "d" band that can overlap with the "s' band to give a composite band. The composite band have six molecular orbitals per metal atom.
Half of the molecular orbitals are the anti bonding.So, maximum bonding occurs when the molecular orbitals contains six electrons i.e. the metal has six valence electrons per each metal atom.
When the maximum bonding occurs then it shows maximum melting point.
So, molybdenum shows melting point at and after that the electrons goes into the antibonding and reaches minimum for cadmium when the anti boning orbital is completely filled. So, the melting point of the cadmium is tex]321^{o}C[/tex].
