Answer: Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.
Explanation:
Explanation:
Speed is the rate of an object moving along a path, whereas velocity is the direction of motion
Electricity is the flow of electric charge
Answer: no
Explanation: a compound is two DIFFERENT chemically bonded. thus two green spheres would represent a molecule
1) We need to find mass of the solution
m=D*V
D= <span>1.725 g/mL
V= 250 mL
m=</span>1.725 g/mL*250 mL= 431.25 g
2) 75% = 0.75
0.75*431.25 ≈ 323 g of NH4NO3
