Answer:

Answer in picture

Explanation:

Answer:

5.6 x 10²⁴ molecules H₂O

Explanation:

9.3 moles * (6.02214076 x 10²³) = 5.6 x 10²⁴

The Avogadro constant = 6.02214076 x 10²³

This constant is the number of particles (such as atoms, ions, or molecules) in one mole of something.

Explanation:

A redox reaction is one in which oxidation and reduction takes place. in the sense of

oxidation being the loss of electrons and reduction the gain of electrons.

Answer:

Photons of light from source X carry more energy than photons of light from source Y

Explanation:

According to Einstein's photoelectric equation, the kinetic energy of the emitted photoelectron depends on the energy of the incident photon and the work function of the metal.

For photoelectrons to be ejected from a metal surface, the energy of incident photon must be greater than the work function of the metal. If not, no electron is ejected.

The energy of photon X must be greater than the work function of the metal while the energy of photon Y is less than the work function of the metal. This brings us to the conclusion that the energy of photon X must be greater than that of photon Y.

Answer:

Nuclear fusion, Conduction, Conduction, Radiation.

The Sun produces energy deep inside its core by fusing hydrogen atoms together to form heavier ones through nuclear fusion. Conduction and convection are used to move heat from the core to the surface.

Radiation is the electromagnetic transmission of heat energy through space. The majority of the electromagnetic radiation that the sun emits and that reaches the Earth is invisible. Only a tiny fraction is visible light. Light consists of waves of various frequencies.

When two objects with different surface temperatures come in contact with one another, conduction happens. Up until they reach the same temperature, heat moves from the warmer to the cooler object. Heat moves through a substance by conduction when molecules collide.

Thus the correct order is Nuclear fusion, Conduction, Conduction, and Radiation.

Answer:

k = -0.006.

T₀ = 15 °C

Explanation:

Hola.

En este caso, considerando la gráfica mostrada en el archivo adjunto, podemos evidenciar que los datos dados se comportan de manera lineal, por lo que basado en la ecuación, T=k*h+To, podemos calcular la pendiente que basicamente es igual a k, tomando dos puntos en la gráfica:

[tex]k=\frac{12-13.5}{750-500}=-0.0006[/tex]

Además, el valor de la temperatura inicial se puede extraer de la tabla, dado que esta es cuando la altura es 0 m, es decir 15 °C.

The concentration of S2−in equilibrium with MnS(s) (sp=4. 6×10−14) and 0.083M Mn2+ is mathematically given as

[s^2-]=61.333*10^{-14}M

Generally, the equation for the solubility constant  is mathematically given as

Ksp=[Mn^2+][s^2-]

Therefore

4.6*10^{-14}=0.075*[s^2-]

[s^2-]=4500/0.075*10{-14}

[s^2-]=61.333*10^{-14}M

In conclusion, The concentration of S2−

[s^2-]=61.333*10^{-14}M

(1) Extraterrestrial impacts, (2) gravitational contraction of the Earth's interior, and (3) the radioactive decay of unstable isotopes are the sources of heat that are not major contributors to Earth's present-day internal heat.

Heat is the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object.

Answer:

Electrons

Explanation:

"Static charges" occur when the number of positive charge and negative charge are not equal. This can be applied to neutral objects by friction, induction and conduction with the help of "electrons."

In friction, the electrons are being transferred between the objects being rubbed together.

In conduction, the electrons are also being transferred from one object to another but not through rubbing; instead through direct contact.

In induction, the electrons are able to react immediately without the need for direct contact.

So, electrons are being utilized in these processes in order to create charge.

What would happen to the rate of the forward reaction if the concentration of nitrogen were decreased? The reaction rate would decrease . What will happen to the rates of the forward and reverse reactions when a catalyst is added? Both forward and reverse rates increase.

Answer:

The answer of this question is density

Answer:

When it is cold, it's hard for the molecules and whatever microscopic organisms live there to move around.

When it is hot, the molecules will move quicker due to a chemical reaction with the atoms and other forms of energy increasing with the heat energy. This reaction happens because 2 forms of energy meet.
