Pb + Mg(NO₃)₂ → Pb(NO₃)₂ + Mg
This reaction would NOT occur because Pb is less reactive than Mg and as such Pb cannot displace the Mg in order for the reaction to occur under normal conditions.
Mg + Fe(NO₃)₂ → Fe + Mg(NO₃)₂
This reaction would occur. This is because Mg is more reactive than Fe and as such can displace it in the reaction, thus allowing the reaction to occur under normal conditions.
Cu + Mg(NO₃)₂ → Cu(NO₃)₂ + Mg
This reaction would NOT occur. Mg is more reactive than Cu, and as such copper cannot displace magnesium in order for the reaction to occur under normal conditions.
There are few elements that can form 12 electron rather
than the usual 8. Therefore these are the possible answers:
Sulfur = 2Na + S --> Na2S <span>
Selenium = 2Na + Se --> Na2Se
<span>Tellurium = 2Na + Te --> Na2Te</span></span>
Answer:
O2 - exhibits dispersion forces as its strongest intermolecular force.
Explanation:
Generally speaking, all biatomic homonuclear molecules, such as N2, O2, F2, do NOT have any dipole moment: the distibution of the nuclear clouds is symmetrical. They are non-polar.
For what concerns heteronuclear molecules, it depends on their geometry.
Dispersion force ( Van der Waal)< dipole dipole < hydrogen bond
Intermolecular forces are forces of attraction between molecules/atoms based mainly on the idea of like charges repel and opposite charges attract.
Based on the polarity of the substance, the type of intermolecular forces existing between substance may be different.
Hey mate!
You stuck?
Sodium Hydroxide is a corrosive formula. It causes severe skin and eye burns and digestive tract burns. Dust or vapor from the formula is extremely irritating to the eyes and respiratory tract. The material reacts to water. Target organs of Sodium Hydroxide consists of Eyes, skin, lungs and the respiratory system.
Hope this helps! :)
I’m standard form it will be 11570000 KL or in scientific notation 1.157x10^7
