Polar bond.
A very common example is H2O.
The oxygen atom has an electronegativity value of about 3.5, while the hydrogen atoms have a value of about 2.2 (each).
Electronegativity describes how “greedy” atoms are with sharing electrons.
Since the oxygen atom has a greater value, it will be more “greedy” with the electrons.
Answer:
D. Chlorine is reduced in reaction 1 and iron is oxidized in reaction 2.
Explanation:
- Reduction is the process where by the Oxidation number or state of an element or substance is reduce.
- Oxidation is the increase in oxidation number or state of any element or substance
Answer:
MnO4- + 5 VO +2 + 11 H2O = 5 V(OH)4+ + Mn+2 + 2 H+
Explanation:
Answer:
oxygen should be the central atom in the middle
Explanation:
hydrogens always go on the outside
Explanation:
Because when two equal forces are applied from opposite directions, they "eliminate" each other.
The train would go right if a 3N force was only applied in the right direction, and it would go left if the same force was only applied to the left.
If a 3N force was applied to the right and a 2N force to the left, it would equal a 1N force to the right (3-2=1).
But there it's 3-3=0, so in practice the force is 0N. Therefore the train won't move.
