nordsb [41]2 years ago
7 0

The nucleus of an atom is positively charged and contains most of the mass if the atom.

<h3>What is an atom?</h3>

An atom is the smallest particle of a an element that can take part in a chemical reaction.

Atoms are made up of other smaller sub-particles which are:

  • neutrons which are neutral
  • protons which are positively charged
  • electrons which are negatively charged

The protons and neutrons are found in the nucleus of an atom

The electrons are found regions around the nucleus.

Due to the positive charge of the protons, the nucleus of an atom are positively charged and is massive.

Nitrogen fixation requires a great deal of energy because the N₂ bond is strong.(d) What would be the most obvious environmental
AleksandrR [38]

Each mole of nitrogen that microbes fix requires the breakdown of 16 moles of ATP (adenosine triphosphate). The energy needed by these microbes is obtained by oxidizing organic compounds. In other words, the nitrogenase enzyme must use a significant amount of energy to convert N2 to NH3.

The great majority of nitrogen on Earth exists as molecular N2, and before to the agricultural and industrial revolutions, the only significant mechanism producing reactive nitrogen was biological nitrogen fixation. Any natural or artificial process known as nitrogen fixation causes free nitrogen (N2), a relatively inert gas present in large quantities in the atmosphere, to chemically interact with other elements to generate more reactive nitrogen compounds like ammonia, nitrates, or nitrites. carbon cycle.

Hydrogen gas has been suggested as a clean fuel because it produces only water vapor when it burns. If the reaction has a 88.9%
GaryK [48]

Answer:

Mass of hydrogen = 667 kg (Approx)

Explanation:

Given:

Mass of water = 593 kg

Yield rate = 88.9%

Find:

Mass of hydrogen

Computation:

Mass of hydrogen =  [Mass of water / Yield rate]100

Mass of hydrogen =  [593 / 88.9]100

Mass of hydrogen = 667.04162

Mass of hydrogen = 667 kg (Approx)
