Answer:
Cl2(g) (green/yellow mix) + 2KBr(s) (white) ---> 2KCl(s) (violet) + Br2(g) (reddish brown)
This chemical reaction is a redox type.
Explanation:
Look at the oxidation state, when the number increase your element gets oxidated, when the number decrease, the elements it's getting reduced.
Answer:
Revisa la explación detallada, por favor.
Explanation:
¡Hola!
En este caso, teniendo en mente la definición de ley de velocidad, es posible recordar que esta tiene la forma genérica:
En donde k es la constante de velocidad, [A] la concentration de cualquier especie A en la reacción y m el orden the reacción. Ahora, hay tres órdenes de reacción, cero, primer, y segundo orden, y esto pasa cuando m=0, m=1 y m=2 respectivamente. Por lo tanto, si la reacción es de orden cero, la rapidez de reacción resulta igual a la constante de velocidad dado que la concentración estaría elevada a la cero y por consiguiente siempre tendrá valor de 1, por lo que la concentración no afecta la velocidad de reacción. Esto anterior se expresa como:
¡Saludos!
Answer:
Atom is the building block of matter. The atom itself made up of subatomic particles electron, proton and neutron.
Explanation:
Long time ago, Greek philosopher thoughts that matter can be divided into smaller particles until a point is reached when the basic unit is obtained which can not be further sub divided. A Greek philosopher Democritus called these basic units "Atom".
Later on modern research showed that atom could be divided into smaller particles electron, proton and neutron. These smaller particles are called sub-atomic particles of atom.
Atoms are the fundamental unit of matter. Every thing in the universe that occupy space and have mass is called matter. we can say that every matter is composed of atoms. while the atom is composed of subatomic particles called electron proton and neutron.
Electron:
The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.
Symbol = e-
Mass= 9.10938356×10-31 Kg
It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.
Proton and Neutron:
An atom consist of positively charged central core (nucleus) that is made up of Proton and neutron. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.
Symbol of proton= P+
Symbol of neutron= n0
Mass of proton=1.672623×10-27 Kg
Mass of neutron=1.674929×10-27 Kg
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons.
Answer:
<h2>1200 kg</h2>
Explanation:
The mass of the vehicle can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>1200 kg</h3>
Hope this helps you
