Between HClO3 and HIO3, which is stronger and why? Question 16 options: 1) HClO3 is stronger because chlorine is in a higher oxi
natima [27]

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.

The rate law for the decomposition of phosphine (PH3) is below. It takes 120. s for 1.00 M PH3 to decrease to 0.250 M. How much
Lubov Fominskaja [6]

Answer: 588.8 seconds

Explanation:

1.00 - 0.25 = 0.75M

4.00 - 0.320 = 3.68M

Therefore,

0.75M in 120 seconds

3.68M in x seconds

Cross multiply:

0.75*x = 120*3.68

x = 120*3.68/0.75

x = 588.8 seconds

zysi [14]

Answer:

The answer to your questions are given below

Explanation:

The answer to the questions given above can simply be obtained by writing the electronic configuration of each atom.

The electronic configuration of each atoms can be written as follow:

Fluorine, F (9) => 1s² 2s²2p⁵

Sodium, Na (11) => [Ne] 3s¹

Helium, He (2) => 1s²

Calcium, Ca (20) => [Ar] s²

Nitrogen, N (7) => 1s² 2s²2p³

How do scientists describe the behavior of particles in solids and plasmas?
blondinia [14]

Answer:

The properties of a solid are that they form at a low temperature, particles have long range order meaning that the particles are fixed in place, the particles have a defined shape and volume, the solid particles are a low-energy state of matter, and solid particles are dense and incompressible. But on the other hand plasma particles form at high temperatures, plasma particles have short range order meaning that the plasma particles have little interaction, plasma particles fill all available space meaning plasma particles have no fixed shape or volume, plasma particles are the highest energy-state of matter, plasma particles are highly compressible, and plasma particles conduct electricity extremely well.
