Answer:
0.5
Explanation:
2NaCl(s) + 2H2SO4(l) + MnO2(s) → Na2SO4(s) + MnSO4(s) + 2H2O(g) + Cl2(g)
Using ideal gas equation,
PV = nRT
28.7torr
Converting torr to atm,
= 0.0378atm
V = 0.597L
T = 27 °C
= 300 K
a) PV = nRT
(0.0378atm) * (0.597L) = n(0.0821) * (300k)
= 0.000915 mol
moles of water and chlorine = 0.000915 mol
From the above equation, the ratio of water to chlorine = 1 : 2
Therefore, mole of chlorine = 0.000915/2
= 0.000458 mol
mole fraction = moles of specie/moles of all the species present
= 0.000458/0.000915
= 0.5
True for both academic and industrial environments.<span />
Answer:
If you meant moles then 3.13144 x 10^24
5.2 mol times 6.022 x 10^23 atoms / mol

Answer:
Explanation:
Atoms generally tend to achieve there octet configuration (i.e have there outermost shell completely filled) and become stable. They do this by participating in chemical bonding (majorly by transferring or sharing electrons). Atoms (of elements) that have very few electrons on there outermost shell (like the group 1 atoms; example is sodium) and atoms that have almost completely filled outermost shell (like the group 7 elements; example is fluorine) are highly reactive because it is easier to lose an electron to become stable and also easier to gain an electron to become stable. However, elements in group zero of the periodic table do not participate in bonding and resist chemical reactions because they have a completely filled outermost shell and are hence stable.
Since, the groups of the periodic table shows the number of electrons in the outermost shell of each member (of a particular group), the chemical properties of each group is usually almost similar.
