Answer : The number of moles of 
produced from the reaction is, 14 moles
Explanation :
The given balanced reaction is,
By the stoichiometry, 1 mole of cesium fluoride react with the 1 mole of xenon hexafluoride to give 1 mole of cesium xenon heptafluoride.
That means the mole ratio of 
As 14 moles of cesium fluoride react with the 14 moles of xenon hexafluoride to give 14 moles of cesium xenon heptafluoride.
Hence, the number of moles of produced from the reaction is, 14 moles
Answer:
Cl
Si
Mg
Na
Explanation:
Ionization energy is the energy required to remove an electron from the valence shell of an atom to form an ion. Since metal are natural givers, they help people. Non metals are receivers hence it would be very hard for them to release their electrons.
For our arrangement, the key is that the ionization energy is expected to increase across the period to a maximum that terminates at the halogens. This is the more reason why halogens have the highest ionization energy and the alkali metals have the lowest.
Hence, from the options in the question, we can see that chlorine would have the highest because it is an halogen in group 17. Also expected is the fact that the ionization energy of that Mg is greater than that if Na. This is because Mg comes after Na in the same period and is thus expected to have higher ionization energy than Na
Answer:
The concentration of the acid is 117.92 ± 0.03 mM.
Explanation:
In this problem, the concentration of NaOH and the volume used is given. The volume pipetted from the acid is also given. The concentration of the acid is given by:
CNaOH * VNaOH = Cacid * Vacid
158.32 * (18.76-0.14) = C acid * 25
C acid = 117.92 mM
The propagation of error for this problem, which is a multiplication is the concentration of the acid multiplied by the error divided by its respective value as shown in the equation below
error = 117.92 * 
The answer is 0.03 mM of uncertainty.
Answer:
La versión moderna de la tabla periódica de los elementos contiene los elementos ordenados según su número atómico creciente, y distribuidos en siete (7) filas horizontales llamadas períodos y dieciocho (18) columnas verticales llamadas grupos, de tal forma que los elementos en el mismo grupo tienen propiedades similares.
