Was there supposed to be a picture?
False, other planets have things we have not discovered yet, but for one thing for sure there are storms and hurricanes on other planets as well.
Answer:
Explanation:
Equation of reaction:
2HCl → H₂ + Cl₂
From the equation of reaction,
From ideal gas equation,
PV = nRT
P = pressure of the ideal gas
V = volume of the gas
n = number of moles
R = ideal gas constant
T = temperature of the gas
At STP,
P = 1.0atm
T = 273.15K
R = 0.082J/mol.K
PV = nRT
1 .0 × 11.2 = n × 0.082 × 273.15
11.2 = 22.398n
n = 11.2 / 22.398
n = 0.50mole
From the equation of reaction,
2 moles of HCl = 1 mole of Cl₂
X moles HCl = 0.5mole
X = (2 × 0.5) / 1
X = 1 mole of HCL
Number of mole = mass / molar mass
Molar mass of HCl = 1 + 35.5 = 36.5g/mol
Mass = number of mole × molar mass
Mass = 1 × 36.5
Mass = 36.5g
36.5g of HCl is required to to produce 11.2L of Cl₂
Answer:
c.O
Explanation:
From the periodic table:
Ionization energy tends to increase from IE6 → IE7 drastically at 13329 to 71345. Hence, from this process, we can infer that the removal of electrons takes place from the inner shell which in turn has a higher affinity for the nucleus. This must be oxygen because oxygen contains 6 valence electrons. The removal of this valence electron after the sixth ionization results in the achievement of a stable nearest Noble gas configuration. Hence, the rapid change in the ionization is obvious from IE6 to IE7.
Thus, the element that relates to the IE trend is oxygen.
