The piece of information that Ryan can use to best identify an element is C. How many protons the element has.

<u>Answer:</u> The correct answer is Option c.

<u>Explanation:</u>

There are 3 subatomic particles: Neutrons, protons and electrons.

  1. Neutrons: These particles does not carry any charge and are located inside the nucleus.
  2. Protons: These particles carry positive charge and are also located inside the nucleus.
  3. Electrons: These particles carry negative charge and are found around the nucleus in the orbits. If an element looses 1 electron, it will carry positive charge and if an element gains 1 electron, it will carry a negative charge.

Element is identified by its atomic number. Atomic number is defined as the number of protons or number of electrons.

If one, identifies the number of protons, then the element is easily identified. Electrons on the other hand are easy to remove or add, so it is not convenient to use the number of electrons in identifying the element.

Hence, the correct answer is Option c.

Semmy [17]

Answer:

No

Explanation:

It is not correct to say that an object with the largest volume has the largest mass.

Mass and volume are not directly related. In fact, the relationship between them can be direct or inverse.

Mass is the amount of matter in a substance. Volume is the space a body occupies.

  • A balloon and a stone for example is a typical one.
  • A balloon has more volume but far lesser mass compared to a stone.
  • A stone, gravel sized has low volume but more massive than a balloon.

Therefore, it is wrong to say a balloon has more mass because it has more volume.

A child has a toy balloon with a volume of 1.80 L. The temperature of the balloon when it was filled was 293 K at a pressure of
Mekhanik [1.2K]

Answer:

2.42L

Explanation:

Given parameters:

V₁  = 1.8L

T₁ = 293K

P₁  = 101.3kPa

P₂ = 67.6kPa

T₂  = 263K

Unknown:

V₂ = ?

Solution:

To solve this problem, we are going to use the combined gas law to find the final volume of the gas. The combined gas law expression combines the equation of Boyle's law, Charles's law and Avogadro's law;

               \frac{P_{1} V_{1} }{T_{1} }   = \frac{P_{2} V_{2} }{T_{2} }

All the units are in the appropriate form. We just substitute and solve for the unknown;

         101.3 x 1.8 / 293    =     67.6 x V₂  /  263

          V₂   = 2.42L

In bullet points: explain the difference between thermal energy, heat and temperature.
sergeinik [125]
  • Thermal Energy- is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

  • Heat-energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects.

  • Temperature- is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion.
