Balance the equation N2 +H20= NH3 + NO

Chemistry
1 answer:
slavikrds [6]3 years ago
8 0

Answer:

N₂   +   3H₂O   →   2NH₃   +  3NO

Explanation:

The reaction expression is given as:

        N₂   +   H₂O   →   NH₃   +  NO

We are to balance this reaction expression.

To do this, assign a,b,c and d as the coefficients that will balance the expression:

              aN₂   +   bH₂O   →   cNH₃   +  dNO

Conserving N: 2a  = c

                    H: 2b  = 3c

                    O: b  = d

let a  = 1, c  = 2, b  = 3 and d = 3

So;

            N₂   +   3H₂O   →   2NH₃   +  3NO

Calculate the amount of heat water absorbs from a piece of hot metal using the following data: 75.0 g of cold water is placed in
AysviL [449]

Answer:

Amount of heat absorbed by water is 2604.54 J.

Explanation:

Amount of heat absorbed by water = m_{water}\times C_{water}\times \Delta T_{water}

where m represents mass, C represents specific heat and \Delta T represents change in temperature.

Here m_{water}=75.0 g , C_{water}=4.184J/(g.^{0}\textrm{C}) and \Delta T = (final temperature - initial temperature) = (29.5-21.2) ^{0}\textrm{C} = 8.3 ^{0}\textrm{C}

So, amount of heat heat absorbed by water

     = (75.0g)\times (4.184\frac{J}{g.^{0}\textrm{C}})\times (8.3^{0}\textrm{C})

     = 2604.54 J

What is the word eletrovent
djyliett [7]

Answer:

Explanation:

Electrovalent is a word often associated with chemical bonding in the field of chemistry. It is special type of bond that occurs between metals and non-metals.

These bond types are interatomic interactions occurring between two atoms to ensure that they attain stable configurations.

  • This bond type is also known as ionic bonds.
  • It occurs between two species with a large electronegative diffference i.e one specie is electropositive and the other highly electronegative.
  • The more electropositive specie is metal and it readily loses its valence electrons.
  • The electronegative non-metal gains the electrons and becomes negatively charged.
  • The electrostatic attraction between the metal and non-metals yields the electrovalent bonds.
