Hydrogen and Oxygen by themselves have 1 and 6 valence electrons, respectively. 8 valence electrons is stable, so the atoms form bonds with each other to achieve 8 valence e-.
1 H atom + 1 H atom + 1 O atom = 8 valence e-
Answer:
453.592 grams
Explanation:
Given
Mass = 1 lb
Required.
Convert to grams using dimensional analysis
Represent 1 lb with x g
In unit conversion, we have that.
1 lb = 453.592 g
So:
Getting the equivalent of lb in g, we have:
x g = 1 lb * (453.592 g/ 1 lb)
x g = 1 * 453.592 g
x g = 453.592 grams
Hence:
The equivalent of 1 lb in grams is 453.592 grams
TLDR: The kinetic energy is determined to be zero.
Kinetic energy is energy of motion; when an object is moving (i.e. it has speed or velocity), it has some amount of kinetic energy. The equation itself looks like so:
KE=1/2(m)(v)^2,
where "m" represents the mass of the object and "v" represents the objects speed or velocity. In this example, the ball has stopped, meaning it has no speed/velocity. This means that the final kinetic energy is determined to be zero or none, due to the lack of motion. Mathematically, you can see this by substituting "0" in for "v" (the ball is stopped):
KE=1/2(m)(v)^2
KE=1/2(m)(0)^2
KE=1/2(m)*0
KE=1/2*0
KE=0 J,
or zero kinetic energy.
Hope this helps! :)
