which atomic particle determines the chemical behavior of an atom the nucleus, neutron, electron, proton or none of these

Answers

Answer 1
Answer: The chemical behavior of an atoms is determine by the formation or destruction of chemical bonds. The chemical bonds are the result of the interaction of the electrons of the atoms. Chemical properties of the atoms are given by how attached are the shell electrons attached to the nucleus and how they interact with other atoms. Chemical changes are the result of exchange valence electrons of the atoms. So, the answer is the atomic particle that determines the chemical behavior of an atom is the electron, because it is the particle that is active in chemical bonding.
Answer 2
Answer:

The electron is the primary atomic particle that determines an atom's chemical behaviour.

Electrons are negatively charged particles that form electron shells or energy levels around an atom's nucleus. They are engaged in the production and breaking of chemical bonds, hence they play an important part in chemical reactions.

The quantity and configuration of electrons in an atom's outermost energy level (valence electrons) are very significant in determining the chemical characteristics of the atom. Because of the identical number of valence electrons, elements in the same group or column of the periodic table frequently show similar chemical behaviour.

When a chemical reaction is in equilibrium, a. the reaction is proceeding at its maximum rate.
b. there is no net change in the amount of substrates or products.
c. the reaction has stopped.
d. there are equivalent amounts of substrates and products.

Answers

Answer: b. there is no net change in the amount of substrates or products.

Explanation:

The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.

Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.

A\rightleftharpoons B

For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction.

Find the grams of iron in 79.2 g of Fe2O3.

Answers

First you find the RFM (Relative Formula Mass) of Fe2O3
Fe2 = 56 x 2
= 112
O3 = 16 x 3
= 48

112 + 48 = 160

Moles = mass/RFM
           = 79.2/160
           =0.495

Then you rearrange the formula
Mass= moles x RFM
        = 0.495 x 112
        = 55.44 g
(To find mass of Iron have to use RFM of total iron in the substance example Fe2 ^^)
