Semmy [17]3 years ago
5 0

Answer:

48 grams O2 and 6 grams H2

Step-by-step explanation:

This is chemistry as well but it's fine.

If you have 3 moles of H20, you need 1.5 moles of O2 and 3 moles of H2, to satisfy the stoichiometry.

There are 32 grams in 1 mole of O2, so 1.5 moles of O2 is 48 grams.

Their are 2 grams in 1 mole of H2, so 3 moles of H2 is 6 grams.

Find an equation of the sphere with center (2, −10, 3) and radius 5. $$25=(x−2)2+(y−(−10))2+(z−3)2 use an equation to describe i
lana66690 [7]

In the x,y plane, we have z=0 everywhere. So in the equation of the sphere, we have

25=(x-2)^2+(y+10)^2+(-3)^2\implies(x-2)^2+(y+10)^2=16=4^2

which is a circle centered at (2, -10, 0) of radius 4.

In the x,z plane, we have y=0, which gives

25=(x-2)^2+10^2+(z-3)^2\implies(x-2)^2+(z-3)^2=-75

But any squared real quantity is positive, so there is no intersection between the sphere and this plane.

In the y,z plane, x=0, so

25=(-2)^2+(y+10)^2+(z-3)^2\implies(y+10)^2+(z-3)^2=21=(\sqrt{21})^2

which is a circle centered at (0, -10, 3) of radius \sqrt{21}.
