Fluorine gas effuses 1.37 times faster than chlorine gas
calculation
Rate of F2/rate of Cl2 =√ molar mass Cl2 / molar mass F2
rate of F2/Rate of Cl2 = √1.868
rate of F2/rate of Cl2 =√ 71/38 = 1.37 times faster than chlorine
Answer:
4. is composed mostly of carbondioxide.
Explanation: It is has a more denser carbon dioxide layer and its hotter than that of Earth. Venus surface also consist of other layers of hazy layer and thick cloud of sulphuric acid droplets.
Answer:
Solids.
Explanation:
In a solid object, particles are packed tightly together in fixed positions even if in a container.
Answer:
In full volume it contain 0.12 moles.
Explanation:
Given data:
Total volume= Vt = 2.9 L
Decreased volume= Vd = 1.2 L
Number of moles of air present in decreased volume= n = 0.049 mol
Number of moles of air in total volume= n = ?
solution:
Formula:
Vt/ Vd = n (in total volume) /n ( decreased volume)
2.9 L / 1.2 L = X / 0.049 mol
2.42 = X / 0.049 mol
X = 2.42 × 0.049
X = 0.12 mol
An anion is an ion that has gained electrons and because of this it has an overall electrical charge that is negative due to the excess of electrons, which is greater than the atomic number or number of protons for the atom.
A. O2- is the anion.
