Chemistry
1 answer:
netineya [11]4 years ago
7 0
If you are talking about the Gold-foil experiment: 
During Rutherford's time, the JJ Thomson (plum pudding) model was the accepted version of an atom. However when Rutherford shot positive alpha particle rays at a piece of gold foil. Some of the particles bounced back, meaning that Atoms had a positive center. Most of the particles went through, which means that Atoms are mostly empty space.

Cual es el calor específico de una sustancia que tiene una masa de 15 g y una capacidad térmica de 0.550 calC
mr Goodwill [35]

Answer:

Explanation:

Q = Ce . m .ΔT

Q : calor  

Ce : calor especifico

m: masa  

ΔT : variación de temperatura

capacidad térmica : 0,550 cal / °C

lectura :

por 1 °C se tiene 0,550 cal

por lo tanto  tenemos datos de la temperatura y del calor

pero no olvidar las unidades en el sistema internacional :

Ce : J / kg . K

J: joules

kg: kilogramo

K: kelvin  

pasar de gramos a kilogramos

pasar de calorías a joules

pasar de grado celsius a kelvin

1000g equivale a 1kg

15g     equivale a 0,015 kg

K= °C + 273 ⇒ formula para pasar de grado celsius a kelvin

K=  1 + 273

K= 274

1 caloría equivale a  4,184 joules

0,550 caloría  equivale a 2,3012 joules

ahora como todos los datos ya están en el S.I remplazamos en la formula

Q = Ce . m .ΔT

2,3012 = Ce . 0,015.274

Ce=0,5599 J / kg. K

How do you think dry cleaning works?
andriy [413]
<h2><em><u>During dry cleaning, the pump pulls solvent from the tank and sends it through the filters to remove any impurities. The filtered solvent then enters the cylinder, where it interacts with the fabrics and removes any soil. The solvent then travels back into the holding tank so it can begin the process again.</u></em></h2>
