I woud say B because jupiter has more of a gravitational pull
Answer & Explenation:
2H2 + O2 -> 2H20 is the balanced equation for the reaction of Hydrogen with Oxygen to form water so
If you have 32g of O2 this is a simple Dimensional analysis problem
32g O2 x 36.03056g H20/31.9988g O2 this way the O2 cancels out and you are left with just the H2O so your raw answer would be 36.0319112, then if your instructor requires a significant figure answer that would be to 2 significant figures the information you were given 32g O2, so as above 36g or Water are produced. Just a different way to view and solve the problem with the balanced equation so you can see the way everything relates to everything else. the molar masses of O2 and H2O are simply found my adding up 2 Oxygens 15.9994g x2 = 31.9988g and H2O = 2(1.00794) + 15.9994 = 18.01258 but you then have to multiply that by 2 because the reaction states you get 2 mols in the reaction so that is where I came up with the 36.03056g for the solution. Hope this helps. Dimensional Analysis is and can be one of the best ways to solve these problems, because not always are you going to be dealing with 1:2 ratios.

h is planck's constant
c is the speed of light
λ is the wavelength of light
Wavelength
<em>Thus, the wavelength of light associated with the transition from n=1 to n=3 in the hydrogen atom is </em><u><em>103 nm.</em></u>
Answer:
1. The body's immense blood supply (when blood vessels dilate or become larger heat loss occurs) When the blood vessels constrict it holds in heat
2. The skins blood supply also helps maintain body temperature (helps maintain homeostasis which is the "normal" state of our body)
3. Humidity in the air effects thermoregulation (heat regulation in the body) by limiting sweat evaporation (usually sweat evaporates into the environment when the humidity is low because the air has low "water levels" per say while you have high "water levels" because of your sweat
An ionic bond is a bond which occurs when there is a
difference in the electronegativity of the atoms. One atom which has a stronger
electronegativity tends to steal the electron of the other less electronegative
atom hence making it more negative (anion), while the other becomes a cation.
So answer is:
<span>b. a cation and an anion</span>
