W = 19.6 N
Carbon monoxide (CO) is the name
The number of protons defines what element it is and also determines the chemical behavior of the element.
Answer is:
A. Na₂S + FeBr₂ → 2NaBr + FeS.
B. MgSO₄ + CaCl₂ → MgCl₂ + CaSO₄.
E. AgNO₃ + NaCl → AgCl + NaNO₃.
Iron sulfide (FeS) has low solubility in water.
Calcium sulfate (CaSO₄) has low solubility in water and it will form white precipitate.
Silver chloride (AgCl) has low solubility in water and it will form white precipitate.
305 x 4 = 1220.
1/4 of 304 = 76.
1220 + 76 = 1296.
You'd need approximately 4 and 1/4 of glasses of milk to get the recommended calcium intake for teenagers.
