Write the nuclear equation for the release of a beta particle by 22888Ra. (Enter the symbol with the mass number in the first (raised) box, the atomic number, or charge, in the second (lower) box, and the element, with charge if necessary, in the third box.) 22888Ra

+

β

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

i would say b

explanation:

but i think i would need more information than that

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
