Which of the following is a product formed whrb no2 and h2o react together a o2 b hno3 c h2 d p(oh)2

Answer : The correct option is, (B)

Explanation :

Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.

The balanced chemical reaction will be,

By the stoichiometry, we can say that 2 moles of react with 1 mole of to give 1 moles of and 1 mole of .

In this reaction, and are the reactants and and are the products.

Hence, the correct option is, (B)

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

- lead + phosphoric acid = hydrogen + lead(ii) phosphate
