Answer:
The volume of the balloon increases in the upper atmosphere.
Explanation:
p1= 1 atm
p2= 0.15 atm
V1= 15.6 L
V2= ?
p1*V1= p2 * V2
V2= (p1/p2)*V1
V2= 104 L
Momentum is conserved in a collision. Momentum is mass*velocity, so you can find your answer by calculating initial and final momentums and setting them equal to each other.
15kg * 3.50 m/s + 9kg * 2.35 m/s = 73.65 kg m/s
73.65 = 9 * 2.8 + 15x
solve for x
x= 3.23
The final velocity is 3.23 m/s
The answer should be d because they are constantly rotating
I’m almost 100 percent sure it’s the first one
When four atomic orbitals are mixed to form hybrid orbitals, 4 x sp3
hybrid orbitals are formed.
<span>Carbon's 2s and all three of its 3p </span>orbitals<span> hybridize to form four sp</span>3 orbitals. These orbitals<span> then bond with four hydrogen atoms through sp</span>3-s <span>orbital </span>overlap, creating methane.
