Identify each pair of elements as likely to participate in ionic bonding when bonded together. Use your periodic table. 1. Sodium & Chlorin (NaCI) :
2. Carbon & Oxygen (CO2):
3. Hydrogen & oxygen (H2o)
4. Iron & oxygen (Fe2o3):
5. Magnesium & Sulfur (MgS):

1) NaCl, 5)MgS

Explanation:

What makes something an Ionic Bond:

For 1) Na has a charge of 1+ and Cl has a charge of 1-. They both come together to form table salt. Their electronegativity is also larger than 2.0. Also Na is a metal and Cl ion is a nonmetal.

For 2) C and O are both nonmetals and are covalent bonds

For 3) Water is a polar covalent molecule because there is a electronegativity difference between H and O, but not great. H and O are also nonmetals.

For 4) While Fe is a metal and O is a nonmetal, their electronegativity difference is not greater than 2.0. This makes it polar covalent.

For 5) Mg is a metal and S is a nonmetal. They have a large electronegativity difference. Also Mg has a charge of 2+ while S has a charge of 2-.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
