Acids and Bases (10G. S, 8F. R, 10H. S, 7A. R]:Question 8
Which of the following is an acid-base reaction?
Select one:
o
Pb(NO.), +2K1 2KNO, + Pbl,
OH SO+ 2KOH → K2SO4 + 2H20
0 C, H, + 502 → 300, + 4H,0
O 2Mg + O2 → 2MgO

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

you didnt put any of the following

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.

the objects have the same charge is correct.
