  • 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.

Si en un laboratorio hay 300 moles de plomo y 300 moles de plata en cual de los dos casos la masa en mayor?
docker41 [41]

Answer:

Esto significa que la masa en las moles de plomo es mayor que en las de plata.

Explanation:

Las moles de los átomos representan la cantidad de átomos presentes. Para saber la masa de los átomos debemos convertir las moles a gramos usando el peso molecular de cada uno de los átomos (207.2g/mol para el plomo y 107.82g/mol para la plata).

La masa de plomo en 300 moles es:

300 moles * (207.2g / mol) = 62160g de plomo

Y la masa de plata es:

300 moles * (107.82g / mol) = 32346g de plata

<h3>Esto significa que la masa en las moles de plomo es mayor que en las de plata</h3>

N2 + 3H2 Right arrow. 2NH3 What is the percent yield of NH3 if the reaction of 26.3 g of H2 produces 79.0 g of NH3? Use Percent
Romashka [77]

Answer:

53.4%

Explanation:

N₂ + 3H₂ → 2NH₃

Given that:

26.3 g of H₂ react with N₂ to produce 79.0 g of NH₃

Then:

The number of moles of H₂ = 26.3g of H₂ * (1 mol of H₂/ 2.02g of H₂)

= 13.05 mol of H₂

The number of moles of NH₃ = 13.05 mol of H₂ * ( 2mol of NH₃/ 3 mol of H₂)

= 8.697 mol of NH₃

The mass of NH₃ = 8.697 mol of NH₃ *( 17.04g of NH₃/ 1 mol of NH₃) = 148.1 g of NH₃

The percent yield = actual yield/ theoretical yield * 100%

The percent yield = ( 79.0 g/ 148.1 g )* 100%

The percent yield ≅ 53.4 %
