The vapor of acetic acid will go to the floor of the room.
This is because the density of acetic acid vapor is equal to 2.07 is higher (almost twice) than the density of air which is equal to only 1
Transferring or sharing electrons between atoms forms a covalent bond.<span> Covalent
bonding is when atoms share electrons. It is a chemical bond that involves the
sharing of electron pairs. These pairs are called bonding pairs. Examples of
compounds that has covalent bonds are CO2, organic compounds, lipids and
proteins.</span>
Answer:
<h2>9.03 × 10²³ atoms </h2>
Explanation:
The number of atoms of Al can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 1.5 × 6.02 × 10²³
We have the final answer as
<h3>9.03 × 10²³ atoms</h3>
Hope this helps you
Answer:
π = 29.3 atm
Explanation:
The osmotic pressure π is given by
π = i MRT, where i=Vant Hoff factor =2 for NaCl ( 2 moles ions/mol NacL)
M = molarity
R = 0.0821 Latm/molK
T = temperature K
Assuming density of solution is 1 g/mL
M= 35 g/58.44 gmol / 1 L = 0.60 M
π = 2.0 x 0.60 mol/L x 0.0821 Latm/kmol x 300K = 29.3 atm
