Question

The reaction: The value of x, y and z are:
Cu+xHNO3(conc)-

Answer 1

Answer:

The value of :

x = 4

y = 2

z = 2

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 :

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

$\diamond$ Chemical reactions are balanced in order to make the law of conservation of mass true in all cases

$\diamond$ Copper reacts with nitric acid to form copper II nitrate, nitrogen dioxide and water

$\diamond$ The reaction is given by :

$\boxed{Cu + 4HNO_3 \rightarrow Cu(NO_3)_2 + 2NO_2 + 2H_2O}$

$\diamond$ Comparing the above reaction with

$\boxed{Cu + xHNO_3 \rightarrow Cu(NO_3)_2 + yNO_2 + zH_2O}$

$\diamond$ Therefore,

x = 4

y = 2

z = 2
