<h2>Let us derive empirical formula </h2>
Explanation:
We are given with compound C₆N₄O₁₀: mass percentage of all is :
For C = 12 x 6 /288=0.25%
For N= 14 x 4 /288=0.19%
For 0= 16 x 10/288=0.5%
The elements present are :
Atomic mass moles Simplest ratio rounding off
C 12 0.25/12=0.020 0.02/0.02=1 2
N 14 0.9/14=0.06 0.06/0.02=3 6
O 16 0.5/16=0.03 0.03/0.02=1.5 3
The empirical formula derived is : C₂n₆O₃
Everything is made of molecules so I don’t think there would be life without molecules..
Answer: Answer:
"The arrangement of atoms or ions in a crystal " is described by the terms body-centered cubic and face-centered cubic.
Explanation:
Face centred cubic system explains the crystal structure where an atom is present at each cubic corner of the crystal and the centre of each cube face. Meaningfully, a closed packed plane where at each "face of the cube" atoms touch the alongside face diagonals.
Whereas in body centric cube system has the lattice point present at the 8 corners of cell and an additional one at the center of the cell. Thus, both explains how the atom or ions are placed or arranged in a crystal.
Explanation: Hope this helps :)
We can rearrange the ideal gas equation:
PV = nRT, where n is the number of moles equivalent to:
n = mass / Mr
PV = mRT/Mr
m/V = PMr/RT
density = PMr / RT; where Mr and R are constant.
<span> <span>It means that the amount of mass will stay the same after the change occurs.</span></span>
