Explanation:
1 mole of C molecules contain=6.023×10^23
0.3 moles of C=6.023×10^23/1×0.3
=1.8×10^23 of C molecules
sorry..not sure
Answer:
the molecules of each substance attract each other through dispersion (London) intermolecular force.whether a substance is solid, liquid or gas depends on the balance between the kinetic energies of the molecules and their intermolecular attractions.
thank you.
Answer:
Fluid Friction
Explanation:
Fluid friction involves a fluid or air. The air resistance on an airplane or water resistance on a boat is fluid friction. Rolling Friction - Rolling friction occurs when a round surface rolls over a surface, like a ball or wheel.
Hydrogen sulfide is a <u>compound</u>
<h3>Explanation</h3>
A compound is a substance composed of two or more element in a fixed proportion and it can be separated into simpler substance and element only by chemical method. Hydrogen sulfide is a chemical compound with H2S formula.
Answer is: <span>volume of 1 M NaOH is 1 ml.
</span>c₁(NaOH) = 1 M.
V₂(NaOH) = 10 ml.
c₂(NaOH) = 0,1 M.
V₁(NaOH) = ?
c₁ - original concentration of the solution, before it gets diluted.
c₂ - final concentration of the solution, after dilution.
V₁ - <span>volume to be diluted.
V</span>₂ - <span>final volume after dilution.
c</span>₁ · V₁ = c₂ · V₂.
V₁(NaOH) = c₂ · V₂ ÷ c₁.
V₁(NaOH) = 0,1 M · 10 ml ÷ 1 M.
V₁(NaOH) = 1 ml.
