Because the modern periodic table is according to icnreasing atomic numbers.Ar has the atomic number 18 and potassium 19 so Argron is placed before K in the Modern periodic table.
Answer:
1.67 gradius Celcius
Explanation:
Please see the step-by-step solution in the picture attached below.
Hope this answer can help you. Have a nice day!
The B stands for Boron which is 5 on the periodic table.
The O stands for Oxygen which is 8 on the periodic table.
There is 1 Boron, It's only 1 because there is only on B which doesn't have coefficent
There is 2 Oxygen, The 2 is from the 2 next to the O
There will be three moles of ions.
Because in an aqueous solution, HCl will break apart into <span>H<span>+ and Cl- ions.
</span></span>HCl -> <span>H+</span><span> + </span><span>C<span>l<span>−
</span></span></span>1.5 HCl -> 1.5 H+ + 1.5 Cl−<span>
So the aqueous solution will have 1.5 moles of hydrated hydrogen ions and 1.5 moles of hydrated chloride ions. So, a total of 3 moles of ions are present in the aqueous solution of 1.5 moles of HCl. </span>
