Answer:
The correct option is;
S is more nucleophiclic than O because S is larger than O therefore S is less well solvated than O
Explanation:
Here we have
As the size of atoms increases, the basicity increases and the nucleophilicity increases. Therefore since S is larger than O it is more nucleophilic than O.
Also we have smaller nucleophiles are more solvated than larger nucleophiles therefore S is less well solvated than O.
Which gives the correct answer as;
S is more nucleophiclic than O because S is larger than O therefore S is less well solvated than O.
Answer:
2 or more
Explanation:
There are 2 or more valid electron dot formulas—having the same number of electron pairs for a molecule or ion—can be written when a resonance structure occur as we know that Sharing of electrons takes place so that atoms achieve noble gas configurations. So, How is it that an electron dot arrangement reflects a covalent bond? An electron dot arrangement represents a pair of dots with the mutual electrons of a covalent bond. A great energy of dissociation from bonds leads to a solid covalent bond.
Answer:
The answer to your question is: 10.67 g/ml
Explanation:
graduated cylinder mass empty= 50 g
+ 30 ml of water = 120 g
+ a rock the level rises 75 ml total mass = 250 gr
density of metal = ?
Formula
density = mass / volume
Process
mass of water = 120 - 50 = 70 g
volume of rock = 75 ml
mass of the rock = 250 - 50 - 120 = 80 g
density of rock = 80 / 75 = 10.67 g/ml
C. Metals higher in the series will replace metal ions in solution that
are lower in the series.
Explanation:
The activity series of metals shows the extent of reactivity of different metals.
On the activity series, the most reactive metals are located higher up on the able whereas the less reactive ones are found at the bottom of the series.
- We can tell if single displacement reactions will occur by simply looking at the reactivity series.
- Metals that are more reactive will displace the ones that are not very reactive that are positioned down the series. Such a reaction will occur.
- Metals lower in the series cannot displace the ones on top because they are less reactive. Such a reaction will not occur.
