Answer: The state of water is determined solely by the conditions of pressure and temperature.

Explanation: because the temperature is held constant for an ideal gas, as P and V change for a given gas sample, the PV products will be constant .

Which equation is a decomposition reaction? Li2CO3 Right arrow. Li2O + CO2 Zn + HCl Right arrow. ZnCl2 + H2 Na2O + CO2 Right arr

Dmitrij [34]

Answer:

Li₂CO₃ ⇒ Li₂O + CO₂ is a decomposition reaction.

Explanation:

In a decomposition reaction, a single substance decomposes, producing two or more different substances. In other words, in this type of reaction two or more substances are formed from a compound. The atoms that form a compound separate to give the products according to the formula:

AB → A + B

It can occur spontaneously, or be aided by a catalyst, heat, or electrolysis.

In this case:

Li₂CO₃ ⇒ Li₂O + CO₂ It is a type of chemical reaction in which a single compound decomposes into two or more compounds. So it is a decomposition reaction.

Fatty acids spread spontaneously on water to form a monomolecular film. A solution containing 0.10 mm^3 of a fatty acid is dropp

lara31 [8.8K]

Divide the volume by the area. Using scientific makes things a bit cleaner.

$0.10\,\mathrm{mm}^3 = 10^{-1}\,\mathrm{mm}^3$

$400.\,\mathrm{cm}^2 = 4\times10^2\,\mathrm{cm}^2$

Then

$\dfrac{10^{-1} \,\mathrm{mm}^3}{4\times10^2\,\mathrm{cm}^2} \cdot \dfrac{\left(\frac{1\,\rm m}{10^3\,\rm mm}\right)^3}{\left(\frac{1\,\rm m}{10^2\,\rm cm}\right)^2} = \dfrac{10^{-1}\times10^{-9} \,\mathrm m^3}{4\times10^2\times10^{-4}\,\mathrm m^2} = \dfrac{10^{-10}}{4\times10^{-2}}\,\mathrm m \\\\ ~~~~~~~~= 0.25\times10^{-8}\,\mathrm m$

Now, 1 m = 10⁹ nm, so

$0.25 \times10^{-8}\,\mathrm m \cdot \dfrac{10^9\,\rm nm}{1\,\rm m} = 0.25\times10^1\,\mathrm{nm} = \boxed{2.5\,\rm nm}$
