Statement:

The best way to measure the mass of an orange is to use a balance. You put the orange and the mass pieces in the same cup on the balance and find out how many centimeters it is. The mass of my orange was 145.

Explanation:

Problem 1

The student has not done a good job in measuring the weight of the orange. In fact, the has complicated his simple problem.

Reasons:

  • Using the mass pieces and the cup to find the weight of the orange is wrong approach.

     He can easily place the orange on the balance and read off the weight.

  • Centimeters is a unit of length. What length is he measuring and recording?

    The unit of weight is in newtons(N).

  • Mass is not read from a balance. A balance gives the weight of substance. Mass is different from weight.

Problem 2

Rewriting to paragraph to correct the errors:

The best way to measure the mass of an orange is to use a balance. You put the orange on the balance and find out how many newtons it is. The weight in newtons can be converted to mass in kilogram. The mass of my orange will be 145kg.

All the following ions have the same charge except Group of answer choices oxide. monohydrogen phosphate. peroxide. permanganate
Triss [41]

All the given species have the same charge except peroxide.

<h3>Charges on ions</h3>
  • The charge on monohydrogen phosphate is negative because of its formula, [HPO4]^{2-}.

  • The charge on permanganate is negative. The formula is MnO^-

  • The charge of oxide (O^{2-}) is negative.

  • The charge on peroxide is ( R−O−O−R) is neutral.

  • The charge on oxalate, C2O4^{2-}, is negative.

Thus, only peroxide is unique.
