Answer:
Neptune and Saturn although Neptune isn't on there so just Saturn.
hope it'll help ya out!
Answer:
4.1M = [CH₃OH]
Explanation:
The equilibrium produced for the reaction between CO and H₂ to form CH₃OH is:
CO + 2 H₂ ⇄ CH₃OH
Where Keq is defined as:
Keq = 26 = [CH₃OH] / [CO] [H₂]²
<em>For concentrations in equilibrium</em>
Replacing in Keq the equilibrium concentrations of CO and H₂, the equilibrium concentration of CH₃COOH is:
26 = [CH₃OH] / [3.4x10⁻¹M] [6.8x10⁻¹M]²
<em>4.1M = [CH₃OH]</em>
Answer:
Technology helps us in many ways.
Explanation:
We can now research the world even more effectively and at a higher level of sophistication thanks to technological advancements. Telescopes, on the other hand, enable us to peer into the far corners of the universe and detect very large objects such as stars. Electron microscope enable us to see smaller objects such as cells and organisms.
We will use the formula for freezing point depression :
but first, we need to get the molality m of the solution:
- molality m = moles of C2H5OH / mass of water Kg
when moles of C2H5OH = mass of C2H5OH/ molar mass of C2H5OH
= 11.85 g / 46 g/mol
= 0.258 moles
and when we have the mass of water Kg = 0.368 Kg
so, by substitution on the molality formula:
∴ molality m = 0.258 moles / 0.368 Kg
= 0.7 mol/Kg
and when C2H5OH is a weak acid so, there is no dissociation ∴ i = 1
and when Kf is given = 1.86 C/m
so by substitution on ΔTf formula:
when ΔTf = i Kf m
∴ ΔTf = 1 * 1.86C/m * 0.7mol/Kg
= 1.302 °C
