V1/T1 = V2 / T2
V1 = 3/4(1700) = 1275
T1 = 10 + 273.15 = 283.15
V2 = 1700
T2 = V2T1
T2 = (1700) (283.15) / 1275
T2 = 377.53 K
The number of Hydrogen atoms = 6 atoms
<h3>Further explanation</h3>
Given
Reaction
N₂ + 3H₂ ⇒ 2NH₃
Required
The number of Hydrogen atoms
Solution
The reaction coefficient of a chemical equation shows the mole ratio of the reacting compound.
On a compound the reaction coefficient indicates the number of molecules
Whereas the subscript after the atom shows the number of atoms in that compound
Product from the reaction : 2NH₃
Number of H-atoms :
= 2 x 3
= 6 atoms
What is the resistance to motion
Answer:
Due to an electron-pair acceptor and donor.
Explanations:
<em><u>Lewis acid</u></em> can be defined as an electron-pair acceptor. An example is Hydrogen ion(H+). This is because it is a proton and it distributes positive charge which means that it accepts electrons(negative charge).
<em><u>Lewis base</u></em> can be defined as an electron-pair donor. This is because it donates electrons to be accepted by the proton. An example is ammonia(NH3).
The reducing agent is donating electrons and therefore becoming oxidised itself. In this scenario elemental zinc (Zn) is in a reduced state and is oxidised to become Zn2+, in doing so it donates electrons to Fe2+, thereby reducing it to elemental iron (Fe).
The elemental Zinc in solid state is therefore the reducing agent as it reduces Fe2+ to Fe(s).
