Adding O2 to the reaction 6CO2 + 6H2O C6H12O6 + 6O2. WHICH WAY WILL THE REACTION SHIFT?
Oxana [17]

Answer:

The reaction will shift to the left to produce more reactants.

Explanation:

According to the Le- Chatelier principle,

At equilibrium state when stress is applied to the system, the system will behave in such a way to nullify the stress.

The equilibrium can be disturb,

By changing the concentration

By changing the volume

By changing the pressure

By changing the temperature

Consider the following chemical reaction.

Chemical reaction:

6CO₂ +  6H₂O  ⇄  C₆H₁₂O₆ + 6O₂

In this reaction the equilibrium is disturb by increasing the concentration of Product.

When the concentration of product is increased the system will proceed in backward direction in order to regain the equilibrium. Because when product concentration is high it means reaction is not on equilibrium state. As the concentration of O₂  increased the reaction proceed in backward direction to regain the equilibrium state and more reactant is formed.

Write word equation followed by chemical equation for the following reactions:a) iron with copper (ll) sulphate b) copper with s
8_murik_8 [283]

Answer:

Iron + copper(II) sulphate → iron sulphate + copper

Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)

copper + silver nitrate → copper nitrate + silver

Cu (s) + 2AgNO3 (aq) → Cu(NO3)2 (aq) + 2Ag (s)

Describe the electrical charges of the particles in atoms
vodka [1.7K]

Answer:

Atom consist of three particles proton , electron and neutron.

electrical charge on electron= -1.6022 × 10∧-19 C

electrical charge on proton= +1.6022 × 10∧-19 C

electrical charge on neutron= 0

Explanation:

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

electrical charge on electron= -1.6022 × 10∧-19 C

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+  

electrical charge on proton= +1.6022 × 10∧-19 C

Mass of proton=1.672623×10-27 Kg

Symbol of neutron= n0

Mass of neutron=1.674929×10-27 Kg

electrical charge on neutron= 0

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.
