Answer:
Number of moles = 0.51 mol
Explanation:
Given data:
Mass of CO₂ = 22.4 g
Number of moles = ?
Solution:
Number of moles of CO₂:
Number of moles = mass/molar mass
Molar mass of CO₂ = 44 g/mol
by putting values,
Number of moles = 22.4 g/ 44 g/mol
Number of moles = 0.51 mol
Answer:
The answer is 4
Explanation:
You divide the grams by the volume which will give you the density
so 19.2 divided by 4.8 equals 4
Answer:
Explanation:
As you move down a group, first ionization energy decreases. WHY? Electrons are further from the nucleus and thus easier to remove the outermost one.
<span>Phospholipids would have to form a phospholipid bilayer in order to achieve water on the outside and water inside. This is because the nonpolar tails of the phospholipids are facing each other in a water environment because they cannot interact with the water, only their own tails, while the phosphate heads of the molecule face the periphery of the tails and interact with water. Micelles are the simplest examples of these.</span>
