Answer:
17 in,3 in, and 19in
so the third answer
Step-by-step explanation:
Let's take radius of the basket ball as b
l<span>et's take radius of the tennis ball as t
b = 3.6 t
</span>volume of the basket <span>ball vb = 4/3 pi b^3
</span>volume of the tennis <span>ball vt = 4/3 pi t^3
</span>
therefore
vb / vt = b^3 / t^3
= (3.6t)^3 / <span>t^3
= 3.6^3
= 46.656
so the volume of the basketball is 46.656 times greater than the volume of the tennis ball.</span>
The reaction is missing and it's ;
N2H4 + H2 ---> 2NH3
It asks for the total pressure too.
Answer:
A) Rate of change for NH3 = 152 torr/h
B) The total pressure in the vessel will remain the same.
Step-by-step explanation:
N2H4 + H2 ---> 2NH3
1 mole of N2H4 yields 2 moles of NH3.
From the question, the rate given for N2H4 is 76 torr/h.
Thus, The rate of change for NH3 will be = 2 x 76 = 152 torr/h
Now, on the reaction side, 1 mole of N2H4 reacts with 1 mole of H2. So we have 2 moles on the left hand side.
While on the product side, 2 moles of NH3 are produced.
So the total pressure will remain the same because for every 2 moles on the reaction side, 2 moles are gotten on the product side.
Answer:
x = 1/25
Step-by-step explanation:
Solve for x:
25 = 1/x
25 = 1/x is equivalent to 1/x = 25:
1/x = 25
Take the reciprocal of both sides:
Answer: x = 1/25
The formula for the volume of a rectangular prism is: l*w*h (length*width*height)
Since the Base area of a 3D figure is always the length times width of the bottom face, all we need to do to find the volume is multiply the Base area by the height.
173.6 (9) = 1562.4 cubic cm
