4. A sodium ion has a +1 relative atomic charge which indicates it has one more proton than electron. This ion is placed in a 4.00 NC electric field. Remember, the charge of one relative atomic charge is 1.60 x 10-19

a. Calculate the force applied to a single sodium ion in this electric field.

Iron reacts with sulfur to form iron sulfide. if 60 grams of iron reacts with sulfur to produce 90 grams of iron sulfide, how much sulfur has been used in the chemical reaction?

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?
