Chemistry
1 answer:
Klio2033 [76]3 years ago
5 0

Answer:

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.

Explanation:

You have to put energy into a molecule to break its chemical bonds. The amount needed is called the bond energy. After all, molecules don't spontaneously break

How would you convert 5 decades to months
katen-ka-za [31]
First, find out how many years are in a decade. There 10 years per decade. So in 5 decades, that makes 50 years. Then multiply 50×12 because there are 12 months in a year. So there are 600 months in 5 decades.

1. 10.0 g of CaCO 3 ​ on heating gave 4.4 g of CO 2 ​ and 5.6 g of CaO. The observation is in agreement with the law of conserva
finlep [7]

Answer:

  1. According to the law <br> Mass of reactants = mass of product, here <br> `underset(10 g)(CaCO_(3))rarr underset(4.4 g)(CO_(2))+underset(x)(CaO)` <br> Hence, x = 10 g - 4.4 g = 5.6 g <br> Which is mass of CaO.d
  2. In the first compound <br> Hydrogen = 5.93 % <br> Oxygen = `(100-5.93)% = 94.07 %` <br> In the second compound <br> Hydrogen = 11.2 % <br> Oxygen `= (100-11.2)%=88.8%` <br> In the first compound the number of parts by mass of oxygen that combine with one part by mass of hydrogen `=(94.07)/(5.93)=15.86` parts ...

La manifestación de un huracán, el movimiento de los aerogeneradores cuando el viento alcanza una velocidad de 3 a 4 metros por
Arturiano [62]

Answer:

Ambos son ejemplos de procesos de transformación de la energía.

El ejemplo del aerogenerador transforma la energía cinética traslacional del viento en energía cinética rotacional del aerogenerador y pérdidas debido a la fricción, la cual es en forma de calor.

En cambio, el ejemplo del hervido del agua es el ingreso de calor por la combustión de madera para aumentar su energía interna.

Explanation:

Son ejemplos de procesos de transformación de energía, por el Principio de Conservación de la Energía se sabe que la energía total de un sistema no se crea ni se destruye, solo se conserva.

El ejemplo del aerogenerador transforma la energía cinética traslacional del viento en energía cinética rotacional del aerogenerador y pérdidas debido a la fricción, la cual es en forma de calor.

En cambio, el ejemplo del hervido del agua es el ingreso de calor por la combustión de madera para aumentar su energía interna.
