Moles = 15.5 g / 40 g/mol = 0.3875 mol
M = 0.3875 mol / 0.250 L = 1.55M
Answer:
If you add the masses of all the products after fission, they are LESS than the mass of the reactants.
Explanation:
A nuclear fission reaction is a radioactive reaction which in which a heavy nucleus spontaneously disintegrates into 2 lighter nuclei and some neutrons with a release of large amount of energy.
When nuclear fission occurs, a mass deficit between the decaying nuclei and the product occurs. It is this mass that actually yields the energy that is produced as a by product of the reaction.
Density is therefore called an intensive property of matter. Mass<span> is the amount of matter contained in an object and is commonly measured in units of </span>grams<span>(g). </span>Volume<span> is the amount of space taken up by a quantity of matter and is commonly expressed in</span>cubic centimeters<span> (cm</span>3<span>) or in </span>milliliters<span> (ml) (1cm</span>3<span> = 1 ml).</span>
Answer:
O 6
Explanation:
Oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
I think the correct answer from the choices listed above is the third option. Areas near large bodies of water tend to not experience large swings in temperature because water has a high specific heat. <span>That's because water can take up lots of thermal energy, and thus preven wild swings in temperature. </span>
