Answer:
2.5 g
Explanation:
I may have misunderstood the question but if there is 10mg of a substance per mL, and there is 250mL, the total would be 10 x 250 = 2500mg = 2.5 g
Answer:
The correct answer is - nuclear fission.
Explanation:
In the given diagram, the reaction is a graphical representation of the nuclear fission of one nucleus of Uranium 235 into two nuclei of Kr with three neutrons that leads to a chain reaction and releases a huge amount of energy and grow out of control.
With every fission, there are two neutrons emitted which results in splitting more nucleus into two nuclei and keep on growing and never die out. The amount of energy also keeps on growing with an increase in the reactions and fission. This reaction is used to generate electricity and nuclear weapons.
Explanation:
a) Barium
b) The metalloid in third period is Silicon
c) Group 4A (or IVA) of the periodic table includes the nonmetal carbon (C)
d) At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.
e) osmium
f) chlorine (Cl, element 17) are a gas at room temperature, and is found as diatomic molecule (Cl2).
I believe the answer is "ions" because the definition of that word is "an atom or molecule with a net electric charge due to the loss or gain of one or more electrons."
Explanation:
The largest water reservoir is the ocean, containing 97.3% of all water on Earth. This is of course salt water and is toxic unless specially treated to remove the salt. The next biggest reservoir are glaciers and polar ice containing just over 2% of the available water.
