Me for part 3: double-displacement reactions: for each of the double-displacement reactions, describe what happened in each well, including the colors of any products that formed. if a chemical reaction occurred, write a balanced equation for it. then using the a, b symbols, write a general equation for a double-displacement reaction. here are the chemical formulas of the reactants for each reaction: • sodium chloride – nacl copper sulfate – cuso4 • sodium hydroxide – naoh copper sulfate – cuso4 • sodium phosphate – na2hpo4 copper sulfate – cuso4 • sodium chloride – nacl silver nitrate – agno3 • sodium hydroxide – naoh silver nitrate – agno3 • sodium phosphate – na2hpo4 silver nitrate – agno3

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

girl imma just put my comment here because i need a couple point okurrttt
