As we know that
A<span>t STP
1 mole of any gas occupies 22.4L
so
15.7L / 22.4L/mole = 0.7moles Cl2
0.7moles x 6.022x10^23molecules/mole = 4.22x10^23molecules
hope it helps</span>
Answer:
I > Br > Cl > F
Explanation:
Bromide (Br), Fluorine (F), Chlorine (Cl) and Iodine (I) are halogens and they are in the same group of the periodic table. We know that as we go down in the group the atomic radius will increase. The decreasing order of the atomic radius will be:
I > Br > Cl > F
The pressure in the flask is 3.4 atm.
<em>pV</em> = <em>nRT
</em>
<em>T</em> = (20 + 273.15) K = 293.15 K
<em>p</em> = (<em>nRT</em>)/<em>V</em> = (1.4 mol × 0.082 06 L·atm·K⁻¹mol⁻¹ × 293.15 K)/10 L = 3.4 atm
Answer:
sodium ion
Explanation:
And, so if we gots a representation of Na+ , or Cl− , we know that for the sodium ion, while there are 11 charged nuclear particles (how do we know this?), there are 10 charged extranuclear particles, 10 electrons.

Answer:
14
Explanation:
The lithium atom has 3, which is its atomic number. (Atomic number is the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.) The chlorine atom has 17, so if you find the difference, it would be 14.
