O The gallium atoms will increase in temperature,

O The gallium atoms will be moving faster on average.

O The gallium atoms will gain kinetic energy.

Answers

Answer 1

The gallium metal melt in a person's hand because the gallium atoms will increase in temperature at its melting point.

What is melting point?

The melting point also called as liquefaction is the process by which the solid substance turns into liquid upon giving heat energy. There is equilibrium established between the solid and liquid phase during melting of a substance.

The gallium metal has low melting point and upon touching a person's hand the atoms heat up and there is increase in temperature which is enough to melt it. The atoms heat up and liquify as it reaches its melting point.

Therefore, when the gallium metal is kept on a person's hand the atoms heat up and melt upon reaching its melting point.

What happens to the atom when the number of each subatomic particle changes?

Answers

Answer:

If the number of protons, neutrons, or electrons changes, it changes the properties of the atom in a major way.

#1 Changing the Proton Number

If you change the number of protons, you completely change the element.



Each element has a certain number of protons. If sodium gained a proton it would become magnesium.

Obviously, it’s a little more complicated than that, but you get the picture. Tell students to leave protons alone.



(By the way, if you are looking for a color coded way to teach finding protons from the atomic number, read this blog post.)

#2 Changing Neutron Number

If you change the number of neutrons, you create isotopes. Isotopes are basically just lighter or heavier versions of an average element.



In fact, the way we calculate the mass number of a given element on the periodic table is to average the light, medium, and heavy versions of that element.

#3 Changing Electron Number

If you change the number of electrons you create ions. A loss of electrons is going to lead to an anion. A gain of electrons is going to lead to a cation.



If you are teaching this principle to your students, make sure they know that most elements tend to form either a cation OR an anion. Not both.

Well, unless you are hydrogen, but he’s “special”.

Subatomic Particles Matter

After explaining all this to your students they will see that the smallest change, or mistake as it is likely to be, will change the whole atom.

It also really helps students to see these principles side by side because many times on tests we ask them what the loss of an electron will do to an atom of Na.

One of the options is usually “Create an isotope”, so this helps clarify the concept so that your students are better prepared for those concepts.

Hope, these help you give a clear and better understanding !

2 NaOH (s) → Na2O (s) + H2O (g)

Answers

The expected mass loss for an 8.87-gram sample of NaOH is 2.00 g.

What is the expected mass loss of a reaction?

The expected mass loss of a reaction is the mass of the reactant that is lost from the total mass of the reactant as a result of some of the products escaping as gases.

The expected mass loss for an 8.87 gram sample of NaOH is calculated as follows:

The equation of the decomposition of NaOH is reaction is given below as follows:

2 NaOH (s) → Na₂O (s) + H₂O (g)

From the equation of reaction, 2 moles of NaOH lose 1 mole of water

Molar mass of NaOH = 40 g

Mass of 2 moles of NaOH = 2 * 40 g or 80 g

Molar mass of water = 18 g

Hence, 80 g of NaOH loses a mass of 18 g

8.87 g of NaOH will lose 8.87 * 18/80 g = 2.00 g

Answers

Electrons are transferred through the respiratory chain from reduced nadh or fadh2 to oxygen in small steps with each step in the pathway associated with a slightly more positive reduction potential.

What is  reduction potential?

Because reduction requires electron gain, an electrode's tendency to gain electrons is referred to as its reduction potential.

The electrode potential is the equilibrium potential difference between the metal electrode and the solution around it. It is also defined as an electrode's proclivity to lose or gain electrons.

When a piece of metal is immersed in a solution of its own ions, a potential difference is formed at the metal-solution contact. The size of the potential difference measures the tendency of electrodes to oxidize or reduce, or to lose or acquire electrons.

The half cell is represented by the metal and the ion, and the reaction is half-reaction. The immersed metal is an electrode, and the potential is caused by a reaction at the electrode's interface, and the solution is known as the electrode potential.
