<span>Each penny is 0.75 inches in diameter
0.061 inches thick
If pennies has a diameter of 6 inches and a height of 11.5 inches
Cylinder: Diameter-6 in/ Height 11.5 in
V=3.14(r²)h
3.14(3²) (11.5)
3.14*9 (11.5)
Volume=324.99
Pennies
Diameter-0.75 in/ Height .061
V=3.14(r²)h
3.14(.375²)(0.061)
3.14*.140625 (.061)
4415625*.061
Volume=0.0269353125
324.99/0.0269353125= 12,065
pennies(approximately)
12,065 Pennies can fit in the cylinder
hope this helps</span>
To make this anion into a complete acid, then this must
be added with Hydrogen ion H+. So the chemical equation looks like:
H+ + SO3(2-)
--> ?
Now to balance it:
H+ + SO3(2-)
--> H2SO3
Answer:
H2SO3
Answer:
my guess is 128 when doing the math its the closest to the actual answer
Answer: 20. First, distribute the 1/10 to inside the parenthesis. You will get 1/10x + 5 = -3x-13+4x. Get all of the x variables on one side, so subtract 1/10x from both sides, and add like variables. You should now have 5 = 9/10x-13. Add 13 to both sides, then divide each side by 9/10. Your answer will be 20. Plug it back into x to check.
