Answer:
The order in which the orbitals is filled is 1s-2s-2p-3s-3p-4s-3d-4p-5s-4d-5p-6s-4f-5d-6p-7s-5f-6d-7p
Explanation:
S orbitals each hold two electrons, p orbitals hold 6, d orbitals hold 10, and f orbitals hold 14. 1s has the least energy and 7 p has the greatest energy, so the order in which they are filled is listed above.
Answer is: <span>B) inner core.
</span>The Sun interior is divided into three regions: the inner core<span>, the </span>radiative zone<span> and the </span><span>convection zone.
</span><span>The inner core is the central region of the Sun and all solar energy is produced in the core by nuclear fusion.
</span>Radiative zone is a<span>round the inner core and in this area</span><span> energy is transported by </span>radiation.
The convection zone is the outer-most layer of the interior and in this area energy is transported by convection.
Answer:
It would decrease
Explanation:
In an ecosystem, organisms feed on one another for survival due to the fact that energy needed for metabolic activities in individual organisms can only be obtained via food. This question depicts that certain bird population feeds on barley plant in an ecosystem.
However, If a disease attacks the plants in such a way that it destroys the barley plants in the field, this would cause the barley-eating bird population to DECREASE because their food source has been affected.
Answer:
The pressures will remain at the same value.
Explanation:
A catalyst is a substance that alter the rate of a chemical reaction. It either speeds up the or slows down the rate of a chemical reaction.
While a catalyst affects the rate, it is noteworthy that it has no effect on the equilibrium position of the chemical reaction. A catalyst works by creating an alternative pathway for the reaction to proceed. Most times, it decreases the activation energy needed to kickstart the chemical reaction.
Hence, we know that it has no effect on the equilibrium position. Factors affecting equilibrium position includes, temperature and concentration of reactants and products( pressure in terms of gases).
The reactants and the products here are gaseous, and as such pressure affects the equilibrium position. Now, we have established that the equilibrium position is unaffected. And as such the pressure affecting it does not change.
Thus, we have established that the pressure of the products and reactants are unaffected and as such they remain at their value unaffected.
