Answer:
Se llaman bioelementos primarios. Los átomos de carbono tienen la capacidad de unirse a otros átomos. Esto permite que tenga lugar la vida y es por eso que el carbono es el bioelemento más importante. Otros elementos químicos se encuentran en los seres vivos; sin embargo, aparecen en pequeñas cantidades.
Explanation:
Answer:
<em>One mole of anything is 6.022×1023 everythings, including atoms. Multiply the moles Fe by 6.022×1023 atoms/mol. 3.77mol Fe ×6.022×1023atoms Fe1mol Fe =2.27×1024 atoms Fe rounded to three significant figures.</em>
Answer is: the collision theory.
The collision theory states that a certain fraction of the collisions (successful collisions) cause significant chemical change.
The successful collisions must have enough energy (activation energy), on this diagram that energy is represented with arrow up.
Chemical bonds are broken (between blue and red-black molecules) and new bonds are formed (between blue-red and blue-black molecules), as it is represented on diagram.
Okay I did the math and I'm guessing around 18*C
Nitric oxide (NO) is the catalyst used for the oxidation of SO2 to SO3 in the lead chamber process for the manufacture of sulphuric acid.
<h3>
Nitric oxide</h3>
The volume of flask =10 liter
(a) 2SO2+O2⇌2SO3K=100
At an x a
end a/10 x/10 a/10
const KC=(x/10)(a/10)2(a/10)2=100
1001=10x⇒x=1/10
0.1 moles of O2 are present .
(b) 2SO2+O2⇌2SO3
At an x 2a
eq a/10 x/10 2a/10
contact
KC=(x/10)(a/10)2(102a)2⇒x/104=100
x=4/10=0.4 moles of O2.
