Answer:
are produces are in a month.
Explanation:
Quantity of eggs produced by the chicken in a month = 284 dozens
1 dozen = 12 eggs
Number of eggs in a month:
are produces are in a month.
On the graph, which shows the potential energy curve of two N atoms, carefully sketch a curve that corresponds to the potential
energy of two O atoms versus the distance between their nuclei.
1 answer:
Answer:
Explanation:
We are to carefully sketch a curve that relates to the potential energy of two O atoms versus the distance between their nuclei.
From the diagram, O2 have higher potential energy than the N2 molecule. Because on the periodic table, the atomic size increases from left to right on across the period, thus O2 posses a larger atomic size than N2 atom.
Therefore, the bond length formation between the two O atoms will be larger compared to that of the two N atoms.

Answer:- 1.90 atm
Solution:- It is based on combined gas law equation, PV = nRT
In this equation, P is pressure, V is volume, n is moles of gas, R is universal gas constant and T is kelvin temperature.
If we divide both sides by V then:
We know that, molarity is moles per liter. So, in the above equation we could replace by molarity, M of the gas. The equation becomes:
P = MRT
T = 20 + 273 = 293 K
M =
Let's plug in the values in the equation:
P =
P = 1.90 atm
So, the pressure of the gas is 1.90 atm.
