How many atoms are in 2 moles of H2O2?
Answer: 1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.
How many atoms do hydrogen atoms have?
two
A hydrogen, nitrogen, or oxygen molecule, consists of two identical atoms of each of those respective elements. Therefore, a hydrogen molecule’s mass is 2 amu, oxygen is 32 amu and nitrogen is 28 amu.
How many atoms are in 2h202?
it contains 2 atoms of hydrogen(H) and 1 atom of oxygen(O). So in total there are 3 atoms. hope it helps you!!
Can I use 3 hydrogen peroxide to whiten teeth?
The hydrogen peroxide you purchase from pharmacies or drugstores is diluted to about 3%. This percentage can reach as much as 10% in many of the teeth whitening products on the market. Dentists believe that dilution is good because a high concentration of hydrogen peroxide can destroy the enamel of your teeth.
How many bananas are in 1 mole?
There also would be 6.02 × 1023 bananas in a mole of bananas, if such a huge number of bananas ever existed. Italian scientist Amedeo Avogadro, whose work led to the concept of the mole as a counting unit in chemistry. The number 6.02 × 1023 is called Avogadro’s number, the number of representative particles in a mole.

How do you whiten your teeth with hydrogen peroxide and Q tips?
Interesting: never buy white strips again!: dip q-tip in hydrogen peroxide (the key ingredient in whitestrips) and apply to surface of teeth for 30 sec before brushing teeth) once a day for a few days. Teeth will look whiter in 2 days.
What is the formula for H2O2?
The formula of the chemical compound Hydrogen peroxide is H2O2
Is H2O2 a covalent bond?
No, H2O2 has only covalent bonds. An ionic bond is always formed between a metal and a non-metal. H2O2 is a weak acid, and so it can ionise slightly in water as a weak electrolyte. Acids like HCl , H2SO4, and HNO3 are also covalent compounds even though they are completely ionised in water.
What is the oxidation number of H2O2?
The oxidation number of oxygen h2o2 is -1. hydrogen peroxide has the ability to gather two or more electrons for h2 ion.so the oxidation number of oxygen becomes -2. it also act as a reducing agent. so inturn oxidation number of oxygen becomes 0.
What is the oxidation state of H2O2?
Oxidation state of the H2O2 molecule is 0. If oxidation state of hydrogen is 1, then oxidation state of oxygen must be -1 (2×1 + 2x(-1) = 0. Here’s a good rule for oxygen’s oxidation states: In oxides, it is -2, except for oxide with fluorine where is 2. (oxide ion: O^2-) In peroxides, it is -1.
