Answer:
2) HClO3 is stronger because chlorine is more electronegative than iodine.
Explanation:
The more electronegative the element is the more strong or acidic it becomes.
Chlorine being more electronegative than Iodine makes it easier for it to pull the electron of hydrogen more strongly and hence has a higher tendency to release a H+ unit. Hence that makes it stronger.
Answer:
0.268 L
Explanation:
concentration is the number of moles of solute in 1 L of solution
number of moles of KCl - 5.0 g / 74.5 g/mol = 0.067 mol
the concentration of the solution to be prepared - 0.25 mol/L
concentration = number of moles of KCl / volume of solution
substituting the values in the equation
0.25 mol/L = 0.067 mol / V
V = 0.268 L
solution should be diluted to 268 mL to make a 0.25 M solution
Answer: The number of Ni2+ ions is 1.46 × 10^18 ions
The number of Ag+ ions is 2.92 × 10^18 ions

I am pretty sure it is nitrogen, oxygen, carbon and hydrogen.
In the herbicide linuron whose structure is shown in the image attached, there are four pi bonds.
A pi bond is formed by a sideways overlap of atomic orbitals. A sigma bond is formed by an end to end or head to head overlap of atomic orbitals. Pi bonds lead to the occurrence of multiple bonds in the molecule.
In the herbicide linuron whose structure is shown in the image attached to this answer, there are four pi bonds which are easily spotted as double bonds in the structure.
