Basically, the arrangement of electrons in electronic configuration follows three principles:
1. Aufbau Principle
You start from the highest energy level to the lowest. The arrangement is: <span>1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s<5f<6d<7p.
2. Hund's Rule
Each box in the configuration can hold up to 2 electrons. This rule tells you to fill all boxes of one particular subshell with 1 electron first, before double occupying them.
3. Pauli's Exclusion Principle
This rule tells you that the two electrons in a box shall always have opposite spins, represented by one half-arrow up and one half-arrow down.</span>
It becomes:
6CO2 + 6H2O -> C6H12O6 + 6O2
<span>Our Earth is structured around the densities of the materials which make it up.One property of density is that it determines the way materials in a mixture are sorted. This property of matter results in the layering and structure of Earth's atmosphere, water, crust, and interior.</span>
Each substance has its own unique structure and properties that are based on these structures.
One of those most important properties is the "specific heat" value.
Specific heat is defined as the amount of heat required to raise the temperature of a unit mass of a substance by 1 degree Celsius.
Each substance has its own specific heat. The higher the specific heat of a substance, the longer it will take to heat up or cool down.
Hope this helps :)
Q=MCdeltaT
*make sure you change celcius into Kelvin*
Q=20(4.18)(20)
Q=1,672
It requires 1,672 Joules
