Answer:
But when we are talking about larger scales, like astronomical ones, gravity is dominant. The main reasons for this are that gravity has a longer range than the other forces (this shows that distance is important in both cases), and the second reason is that there is nothing in existence with negative mass.
The correct answer is Iron and magnesium

Answer:
El volumen del gas en el recipiente es 3.29 L si se disminuye la temperatura a 7°C
Explanation:
La Ley de Charles es una ley de los gases que relaciona el volumen y la temperatura de una cierta cantidad de gas a presión constante.
Esta ley establece que el volumen es directamente proporcional a la temperatura del gas. Es decir que si la temperatura aumenta, el volumen del gas aumenta, mientras que si la temperatura del gas disminuye, el volumen disminuye.
Matemáticamente, si la cantidad de gas y la presión permanecen constantes, el cociente entre el volumen y la temperatura siempre tiene el mismo valor:
Suponiendo un cierto volumen de gas V1 que se encuentra a una temperatura T1 al comienzo del experimento, al variar el volumen de gas hasta un nuevo valor V2, entonces la temperatura cambiará a T2, y se cumplirá:
En este caso, sabes:
- V1= 3.5 L
- T1= 25 °C=298 °K (siendo 0°C=273°K)
- V2=?
- T2=7 °C=280 °K
Reemplazando:
Y resolviendo obtienes:
V2= 3.29 L
<u><em>El volumen del gas en el recipiente es 3.29 L si se disminuye la temperatura a 7°C</em></u>
No of atoms in 4.8 dm³ of neon gas is determined in the following way.
Explanation:
We have given
Neon Gas=4.8dm³
At STP
1 mole of an ideal gas occupies 22.4 L(dm³) of volume.
which means that number of molecules occupy 22.4 L of volume.
So
4.8 dm³x 1 mole/22.4 dm³ = 0.214 moles Neon
0.214 moles x 6.02x10²³ atoms/mole = 1.29x10²³ atoms of Neon
No of Atoms in 4.8dm3 neon gas =1.29x10²³ atoms of Neon

Answer:
Energetic molecules are formed, or rather the energetic currency to be able to live, which we call ATP.
Explanation:
ATP is a molecule that arises from the degradation of carbohydrates, these are destroyed for the first time in the mouth by the enzyme salivary amylase, then by the stomach, and finally they are absorbed in the intestine in the form of glucose, this glucose enters the bloodstream, entering the cells through insulin.
Once glucose is entered into the cell, it completes an energetic cycle, called the krebs cycle, which provides 36 to 38 ATP.
Atp, is adenosine tri phosphate, phosphate bonds protect a lot of energy, this is how the body generates the following reaction when it needs energy, releasing energy to the environment to be able to produce from locomotion to respiration:
ATP -----> ADP + Pi
