Hi there!

We can use pythagorean theorem to solve this problem here. The easiest way to go about solving this problem is to use the theorem to find the hypotenuse, then dividing it by 5 to find the value of x, since the hypotenuse is 5x.

WORK:
27^2 + 36^2 = h^2     (plugging into theorem)
729 + 1296 = h^2     (squaring the numbers)
h^2 = 2025              (adding the numbers together)
hypotenuse = 49    (taking the square root of 2025)
49/5 = x                 (dividing 49 by 5 to find x)
x = 9.8                  (dividing)

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

If 0.278g of argon dissolves in 1.5 l of water at 62 bar, what quantity of argon will dissolve at 78 bar
irinina [24]
When P1/P2 = C1/C2

and C is the molarity which = moles/volume

so, P1/P2 = [(mass1/mw)/volume] / [(mass2/mw)/volume]

P1/P2 = (mass1/mw)/1.5L / (mass2/mw)/1.5L 

so, Mw and 1.5 L will cancel out:

∴P1/P2 = mass1 / mass2

∴ mass 2 = mass1*(P2 / P1)

                = 0.278g * (78 bar / 62 bar)

                = 0.35 g

∴ the quantity of argon that will dissolve at 78 bar = 0.35 g

What will the ratio of ions be in any compound formed from a group 1a and a group 7a nonmetals?
julsineya [31]
Group 1a elements (the first column on the left side of the Periodic table) always release one electron to form positive ions with a charge of +1. Group 7a nonmetals (the <em>second to the last </em>column on the right side- the rightmost column are the noble gases) always desire to gain one electron to form negative ions with a charge of -1.
Since their charges are equal and opposite, they will always combine in a 1:1 ratio.
