Question

name the gas evolved when Mg is reacts with diluted HNO3 WITH EQUATION

Answer 1

Answer:

The gas evolved is hydrogen gas (H₂ gas)

Explanation:

$\diamond$ Chemical reactions are processes in which one or more substances (reactants) react or combine together to form one or more substances (products)

$\diamond$ A general chemical reaction can be given as :

$\huge \text{\boxed{\mathcal{REACTANTS \rightarrow PRODUCTS}}}$

$\diamond$ When magnesium reacts with nitric acid it produces magnesium nitrate and hydrogen gas

$\diamond$ The balance chemical equation is given by :

$\boxed{Mg + 2HNO_3 \rightarrow Mg(NO_3)_2 + H_2}$

$\diamond$ In the given reaction,

magnesium [ Mg ] and nitric acid [ HNO₃ ] are the reactants and

magnesium nitrate [ Mg(NO₃)₂ ] and hydrogen gas [ H₂ ] are the products

Answer 2

Answer:

when Mg  reacts with Dil. HN03 the products formed is Mg(N03)2 and the gas which  is evolved is Hydrogen (H2) gas...

This type of reaction is called a displacement reaction as more reactive metal displaces a less reactive metal from its salt solution .

  The Balanced chemical equation of magnesium with nitric acid is:

Mg (s) + 2HN03 (l) → Mg(NO3)2 + H2

In this reaction magnesium (Mg) and nitric acid (HN03) are reactants because they formed Magnesium nitrate ( MG (NO3)2) which is a product ..
