Question

write the equations for the following

1. copper + oxygen =

2. magnesium + oxygen =

3. sodium + oxygen =

4. potassium + oxygen =​

Answer 1

1. c +o2- co2

2. mg+o2 - mgo

3. na-o2- na2o

4. k+o2-k2o

Answer 2

Answer:

1. copper (Cu) + oxygen (O2) --> copperoxide (CuO)

2. magnesium (Mg) + oxygen (O2) --> Magnesium oxide (MgO)

3. sodium (Na) + oxygen (O2) --> sodium oxide (Na2O)

4. potassium (K) + oxygen (O2) --> potassium oxide (K2O)

Hope it helps.
