By the process of respiration and photosynthesis; carbon dioxide is obtained and also carbon dioxide in huge amount is produced from the industries which enters in the atmosphere. Carbon dioxide is one of the greenhouse gas.
Greenhouse gases are those gases which are able to trap the radiation in the atmosphere and which keeps Earth warmer. Thus, high levels of carbon dioxide gas keep the temperature of Earth warmer.
Answer:
The Bismuth atom
Explanation:
it contains 83 atoms, 5 of which are valence electrons. These 5 electrons are accommodated in the 6s and 6p orbital.
Explanation:
The given data is as follows.
T = 298 K, = -5645 kJ/mol
= -5798 kJ/mol
Relation between and are as follows.
=
-5798 kJ/mol = -5645 kJ/mol -
-153 kJ/mol = -
= 0.513 kJ/mol K
Now, temperature is = (37 + 273) K = 310 K
Since, =
=
= (-5645 kJ/mol - 159.03 kJ/mol)
= -5804.03 kJ/mol
As, change in Gibb's free energy = maximum non-expansion work
= -5804.03 kJ/mol - (-5798 kJ/mol)
= -6.03 kJ/mol
Therefore, we can conclude that the additional non-expansion work is -6.03 kJ/mol.
The mass of iron (III) oxide (Fe2O3) : 85.12 g
<h3>Further explanation</h3>
Given
3.20x10²³ formula units
Required
The mass
Solution
1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mol of Fe₂O₃ :
mass of Fe₂O₃ (MW=160 g/mol)
