The sun affects the movement of global winds by heating up the water at Equator
Answer:
Earthquakes are more intense the faster the planet's crust slams together, which explains why the shaking causes so much damage in some of the most populated areas around mountain chains. ... One reason for this connection is that when two plates come together quickly, the area over which an earthquake occurs is larger.Explanation:
The periodic table is arranged by the outermost electrons of the elements and this is the statement among the given statements that explains how the periodic table is arranged. The correct option among all the options that are given in the question is the second option or option "B".
Answer:
KO₂ is limiting reactant
Explanation:
Based on the balanced reaction:
2CO₂ + 4KO₂ → 2K₂CO₃ + 3O₂
<em>2 moles of CO₂ react with 4 moles of KO₂.</em>
<em />
Thus, for a complete reacction of 0.25 moles of CO₂ are required:
0.25 moles * (4moles KO₂ / 2moles CO₂) = 0.5 moles of KO₂
As there are just 0.1 moles:
<h3>KO₂ is limiting reactant</h3>
The phrasing of this exercise means that we have to exclude 3 out of the 4 choices.
We have that the 4 quantum numbers that an electron has are the defining numbers of that electron. The first coordinate, the principal quantum number ncan take any positive value since it defines the shell in which that electron is.
The second number is called the orbital angular momentum number and takes the values from 0 to n-1 (the integer ones) where n is the principal number. Hence, we can disqualify options 1 and 4; the 1st because the principal and the orbital number are the same which is not possible and the 4th because the orbital number is negative which is not possible.
The third is the magnetic quantum number and takes values from -l to l (all integer values in between). Hence, it cannot be equal to n again, so option 2 is disqualified too.
The only remaining option that is correct is 3)
P.S. We have a 4th number, the spin number; this number can assume only the values +1/2 and -1/2
