Which is the most accurate description of ionic and covalent bonding?

Yuliya22 [10]

Ionic Bonding:
This type of bonding occurs when atoms want to fulfil their valence shells by taking/giving electrons to other atoms. This, leads to completed valence shells in most cases and ionisation of both elements. The opposite charges cause the elements to stick together because opposites attract.

Covalent Bonding:
This type of bonding occurs when electrons are shared between atoms to each fill up their own valence shells by sharing. The balance between the attraction forces and repulsion forces between the shared electrons is called covalent bonding.

Hope I helped :)

Why is respiration an exothermic reaction?

Degger [83]

Answer: A large amount of energy is released into the surroundings.

Explanation:-

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and $\Delta H$ which is difference between energy of products and energy of reactants come out to be positive.

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and $\Delta H$ which is difference between energy of products and energy of reactants comes out to be negative.

Thus a reaction in which large amount of energy is released is categorized as exothermic reaction and thus respiration is also a exothermic reaction.

What is the limiting reactant if 12 moles of p4 react with 15 moles of o2?.

brilliants [131]

Answer:

see explanation

Explanation:

To determine limiting reactant divide mole quantities of reactants by the respective coefficient in the balanced equation. The smaller value is the limiting reactant.

P₄ + 5O₂ => 2P₂O₅

12/1 = 12 15/5 = 3

O₂ is the limiting reactant. P₄ will be in excess when rxn stops.

What type of compound is created when potassium and chlorine combine?

poizon [28]

Answer : The type of compound created is Ionic compound and the chemical formula is KCl.

Explanation :

Potassium has 1 electron in its valence shell and chlorine has 7 electrons in its valence shell.

The potassium loses 1 valence electron & make a positive charged ion and chlorine picks it up & make a negative charged ion and then they attract to each other.

Potassium and chlorine atom combine to form potassium chloride by the ionic bonding.

An ionic compound is made of a metal and non-metal element. And in this case, potassium is a metal element and chlorine is a non-metal element.

The ionic compound formation is,

$K+Cl\rightarrow KCl$

The Chemical formula is KCl.
