Need help on these please and thank you
Snowcat [4.5K]

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.

Talja [164]

Answer:

ions

Explanation:

Individual atoms of the same element but having slightly different number of protons and electrons are called ions.

Ion is a charged particle.

  • An atom is made up of three fundamental subatomic particles.
  • Protons are the positively charged particles
  • Electrons are the negatively charged particles
  • Neutrons do not carry any charges.

When the number of protons > electrons the body is positively charged.

When the number of electrons > protons the body is negatively charged.

Charged particles are called ions.

vfiekz [6]

Answer:

There are two possible answers to the question

I) decreasing the pressure of the system

II) decreasing the temperature of the system

Explanation:

Looking at the equation of the reaction, it can be seen that the reaction is endothermic. This implies that decreasing the temperature favours the reverse reaction and more NO2 is produced.

Secondly, decreasing the pressure drives the equilibrium position towards the side having the higher total volume hence decreasing the pressure favours the reverse reaction and more NO2 is produced.
