Answer:

The production of hydrogen releases CO₂.

Explanation:

Hydrogen is not a primary fuel, it means that it is not available to be used directly, it must be produced. The production generally uses fossil fuels, and in that case, CO₂ is produced, which is a greenhouse gas (GHG).

So, to obtain that fuel, CO₂ is released, which has a negative effect on the environment because it intensifies the greenhouse effect and global warming.

Advocates for the use of hydrogen fuel cells posit that unlike other sources of power, these fuel cells do not emit harmful carbon emissions in the air that cause pollution and affect global warming. Although the chemical process involves burning hydrogen<span>, it emits water, heat and other emissions but not carbon.

I hope my answer has come to your help. God bless and have a nice day ahead!

What ion is at a higher concentration in the extracellular fluid than in the intracellular fluid?
Phoenix [80]
There are two types of fluid in the body extracellular fluid and intracellular fluid (ECF and ICF), together they are account for total body water.
The Sodium (Na+) ion is at higher concentration in the extracellular fluid than in the intracellular fluid. The function of extracellular fluid is that it provide cells to watery environment so that they can easily live and perform their function.

<h2>H_2O  + H_2 + O_2</h2>

Explanation:

1. Water decomposition

  • Decomposition reactions are represented by-

       The general equation: AB → A + B.

  • Various methods used in the decomposition of water are -
  1. Electrolysis
  2. Photoelectrochemical water splitting
  3. Thermal decomposition of water
  4. Photocatalytic water splitting
  • Water decomposition is the chemical reaction in which water is broken down giving oxygen and hydrogen.
  • The chemical equation will be -

        H_2O  + H_2 + O_2

Hence, balancing the equation we need to add a coefficient of 2 in front of H_2O on right-hand-side of the equation and  2 in front of H_2 on left-hand-side of the equation.

     ∴The balanced equation is -

       2 H_2O → 2 H_2 + O_2

2. Formation of ammonia

  • The formation of ammonia is by reacting nitrogen gas and hydrogen gas.

      N_2 + H → NH_3

Hence, for balancing equation we need to add a coefficient of 3 in front of hydrogen and 2 in front of ammonia.

   ∴The balanced chemical equation for the formation of ammonia gas is as  follows -

     N_2+3H→ 2NH_3.

  • When 6 moles of N_2 react with 6 moles ofH_2 4 moles of ammonia are produced.
