The shape that is formed by the free surface, which is called a hyperboloid, or "Gabriel's Horn". The core of a vortex in air is sometimes visible because a plume of water vapor that is caused by condensation in the low pressure and low temperature of the core. An example of this is the sprout of a tornado. Vortices form in stirred fluids and could be observed in phenomena such as smoke rings, whirlpools in the wake of a boat, or the winds surrounding a tornado or dust devil.
The reaction between zinc and silver nitrate is

Moles of Zn = m /M = 599 /65 = 9.2 mol
Moles of AgNO3 = m /M = 1500 /169 = 8.87 mol
Silver nitrate is reacting completely to give silver
Thus, moles of Silver nitrate is equivalent to silver = 8.87
For mass of silver produced
m /M = 8.87 = m /107
m = 949.24 g
Hence, the given quantity of reactants are sufficient to produce 800 g of silver as the amount of silver produced is 949.24 g
Most chemical reactions involve the breaking and formation of chemical bonds. It takes energy to break a chemical bond but energy is released when chemical bonds are formed. If more energy is released than consumed, then the chemical reaction evolves heat and is said to be exothermic.
(Have a good day!)
Si un gaz exerce une pression de 2,00 atm lorsque 20 bouffées de particules sont présentes alors pour 4,50 atm il faut 45 bouffées car 20 bouffées = 2,00 atm donc 2*20=40 +0,5 =4,50
<h3>Answer:</h3>
Chlorine (Cl)
<h3>Explanation:</h3>
Ionization Energy is defined as, "the minimum energy required to knock out or remove the valence electron from valence shell of an atom".
Trends in Periodic table:
<em>Along Periods:</em>
Ionization Energy increases from left to right along the periods because moving from left to right in the same period the number of protons (atomic number) increases but the number of shells remain constant hence, resulting in strong nuclear interactions and electrons are more attracted to nucleus hence, requires more energy to knock them out.
<em>Along Groups:</em>
Ionization energy decreases from top to bottom along the groups because the number of shells increases and the distance between nucleus and valence electrons also increases along with increase in shielding effect provided by core electrons. Therefore, the valence electrons experience less nuclear attraction and are easily removed.
<h3>Conclusion:</h3>
As Barium is present down the group and to the left of periodic table, K present at the left of the periodic table, Arsenic present below Phosphorous will have less ionization energies as compared to P. Hence, only Chlorine present at the right extreme of periodic table and right to P will have greater Ionization energy.
