Answer:
There is a lot of empty space between them
Explanation:
We know that gas molecules are loosely packed,
Therefore there is a lot of intermolecular space...(Which basically means that there is a lot of space between the molecules or particles in a gas)

The molarity of KOH is 0.1055 M
<u><em> calculation</em></u>
Step 1: write the equation for reaction between H₂C₂O₄.2H₂O and KOH
H₂C₂O₄.2H₂O + 2 KOH → K₂C₂O₄ +4 H₂O
step 2: find the moles of H₂C₂O₄.2H₂O
moles = mass÷ molar mass
from periodic table the molar mass H₂C₂O₄.2H₂O= (1 x2) +(12 x2) +(16 x4) + 2(18)=126 g/mol
= 0.2000 g ÷ 126 g/mol =0.00159 moles
step 3: use the mole ratio to calculate the moles of KOH
H₂C₂O₄.2H₂O : KOH is 1:2
therefore the moles of KOH =0.00159 x 2 = 0.00318 moles
step 4: find molarity of KOH
molarity = moles/volume in liters
volume in liters = 30.12/1000=0.03012 L
molarity is therefore = 0.00318/0.03012 =0.1055 M
Compounds are made up of elements that exist in a fixed proportion. These elements are composed of atoms. Now, the atom has subatomic particles (proton, neutron and electrons), however, these particles lack the ability to take part in chemical reactions by themselves; the smallest unit of a compound that can take part in a chemical reaction, therefore, is an ATOM.
Thus, an AT<span>OM is the smallest unit of a compound that retains the unique properties of the compound</span>
D. They act on a specific type of substrate in a reaction
Hope this helps!
Yes, it would be the last one as the zeros that appear after a non zero number are significant.
