Answer: The pressure exerted by the gas, in atm is 1.092
Explanation:
According to the ideal gas equation:'
P = Pressure of the gas = ?
V= Volume of the gas
T= Temperature of the gas = (0°C = 273 K)
n= moles of gas =
R= Value of gas constant = 0.0821 Latm/K mol
as
where d is density
Thus pressure exerted by the gas, in atm is 1.092

a man holding a baseball is potential energy, but when the ball is thrown, it is kinetic
Answer: a) 0.06 M
b) 3.13 grams.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Moles of
The balanced reaction for dissociation will be:
Thus for 4 moles of , there is 1 mole of
Thus moles of
Molarity of
Thus the molarity of the solution = 0.06 M
b) Mass of =
Thus mass of Wenzhou use is 3.13 grams.
Answer:
F
O
N
Mg
Explanation
The key explanation here is that we need to know the trends in electronegativity value increase or decrease across the periods and down the group.
Across the periods, electronegativity is expected to increase. Hence, with the exception of the noble gases, the most electronegative elements are found further right on the periodic table. While electronegativity is expected to increase across the period, it decreases down the group.
Hence, if two elements are in the same group, further down we have the one with the less electronegative value. If two elements are in the same period, further right we have the more electronegative element.
