Answer:
8.55 × 10²² Molecules
Solution:
Step 1: Calculate the Mass of Water as;
Density = Mass ÷ Volume
Solving for Mass,
Mass = Density × Volume
Putting values,
Mass = 1 g.mL⁻¹ × 2.56 mL
Mass = 2.56 g
Step 2: Calculate Moles of Water as,
Moles = Mass ÷ M.Mass
Putting values,
Moles = 2.56 g ÷ 18 g.mol⁻¹
Moles = 0.142 mol
Step 3: Calculate Number of Molecules of Water as,
# of Molecules = Moles × 6.022 × 10²³
Putting value of mole,
# of Molecules = 0.142 × 6.022 × 10²³
# of Molecules = 8.55 × 10²² Molecules
Answer:
Step 1: Identify the Individual Ions from the Reactants and Their Charges
Step 2: Switch the Cations and Anions of the reactants
Step 3: Balance the Chemical Reaction
Explanation:
i hope i helped =)
A. The acidity of a solution
Logically, since the net force has been doubled and now two people are moving a wagon in the same direction, the acceleration will increase. I hope this helps!
Carbon tetrachloride looks like this
Cl
Cl-C-Cl
Cl
Whereas methane looks as so,
H
H-C-H
H
——————————————————————
In structure/geometry, they’re the exact same. They have the same surface area, and neither one is polar.
The only attribute to the difference in boiling points is the total molecular weights of the atoms
CH4 is MUCH lighter than CCl4, making the molecules easier to float around.
