I Melt With You: we need assistance with chemistry questions?
Which skill is evil of ionic but
NOT of covalent compounds?
1. soft, non-crystalline structure
2. non-conductor of physical phenomenon in molten
state
3. tall melting point
4. low hot point
5. simply vaporizes
An component E has a electronic configuration
[Ne] 3s

. Write a regulation of a devalue with sulfate.
1. E2(SO4)3
2. E2(SO4)
3. E3(SO4)
4. E(SO4)3
5. E(SO4)2
6. E3(SO4)
For a proton to be polar, which of a following contingency be true?
1. It contingency have frigid bonds.
2. The geometry of a proton contingency be
such which a down payment dipoles do not cancel.
3. It contingency have frigid holds as well as a geometry of a proton contingency be such which the
bond dipoles do not cancel.
4. It contingency have frigid holds as well as it must
contain usually CO as well as hydrogen
You have been since a representation of an unknown
substance. You find out which it does not
dissolve in water, has a really tall melting
point as well as conducts physical phenomenon when molten.
The piece is probably
1. a covalent compound
2. sodium chloride.
3. C8H18.
4. an ionic compound
ONLY apportionment forces existent in in between the
molecules?
I. HBr;
II. CCl4;
III. CH2Cl2;
IV. NH3.
1. we as well as IV only
2. II only
3. III as well as IV only
4. III only
5. IV only
6. we only
7. we as well as II only
8. we as well as III only
9. II as well as III only
10. II as well as IV only
Dipole-dipole forces are
1. in in between a force for ±1 ions as well as ±2
ions.
2. incomparable than ion-ion forces.
3. about a cause of dual not as big than the
attraction of ±1 ions.
4. most not as big than ion-ion forces.
5. about a same as all ion-ion forces
I’m so mislaid
Answer by Michael
I’d be a small some-more prone to answer if we didn’t write out so most questions in 1 subject box.
