Density = mass/volume
Since at STP, one mole of any gas occupies 22.4 liters, therefore, the volume is equal.
So, we will arrange based on mass.
From the periodic table:
mass of carbon = 12 grams
mass of calcium = 40 grams
mass of chlorine = 35.5 grams
mass of copper = 63.5 grams
Based on this:
copper has the highest density.
<span>3.5 moles CaCO3 (1 mole carbon/1 mole CaCO3) = 3.5 moles</span>
When water molecules align with each other, a weak bond is established between the negatively charged oxygen atom<span> of one water molecule and the positively charged </span>hydrogen atoms<span> of a neighboring water molecule. The weak bond that often forms between </span>hydrogen atoms<span> and neighboring atoms is the hydrogen bond.</span>
Answer:
Monatomic ions are made up of only one atom per ion, whereas polyatomic ions are made up of numerous atoms per ion.
