Are you friend with Nitrogen and Oxygen

Chemistry
1 answer:
Oduvanchick [21]3 years ago
8 0

Nitrogen and oxygen do not react at ambient temperature. At high temperatures they have endothermic reactions and produces various oxides of nitrogen.

Explanation:

The difference between nitrogen and oxygen is the nitrogen has seven protons and seven electrons surrounding the nucleus. Whereas the oxygen has eight protons and electrons.

The atoms combines with one another to form molecules. The nitrogen is a inert, colorless gas with no smell or taste, its harmless to human beings.

The oxygen and nitrogen are abundant gases in the atmosphere and have similar physical properties. The oxygen (O2) is twice as soluble in water as nitrogen (N2).

A diatomic molecule shares three pairs of electrons. What type of bond is present in the molecule? A single covalent bond becaus
VMariaS [17]
<h3><u>Answer</u>;</h3>

A triple covalent bond because each atom requires three more electrons to complete its octet.

<h3><u>Explanation</u>;</h3>
  • A triple covalent bond is a covalent bond formed by atoms that share three pairs of electrons.
  • For example;<em><u> in a diatomic molecule such a nitrogen; A nitrogen atom has five valence electrons, which can be shown as one pair and three single electrons. </u></em>When combining with another nitrogen atom to form a diatomic molecule, the three single electrons on each atom combine to form three shared pairs of electrons.

When Earth is tilted on its axis why does it orbit the sun ?
Brrunno [24]

Answer:

Here

Explanation:

Some assume our planet's changing distance from the sun causes the change in the seasons. That's logical, but not the case for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun

Explain how lines latitude and longitude help people find locations on earth.
Bad White [126]
Latitude and longitude are the x and y axis on a grid. When you're trying to find a location on earth, you need to graph it, so you can pinpoint the location. There is no grid if there is no longitude and/or latitude lines. Without one of the lines, it would be very hard to graph, which will be difficult in finding locations on earth. But hey, I'm not too sure. I recommend looking at other people's answers too and searching it up.

If 251 mL of 6.0 M H2SO4 is diluted to 500. mL, what is its new molarity?
kolezko [41]

Answer:

  • <u>3.0M</u>

Explanation:

The dilution formula is:

       M_1\times V_1=M_2\times V_2

Where M₁ and M₂ are the molar concentrations and V₁ and V₂ are the volumes of the concentrated and the diluted solutions.

Substitute:

  • M₁ = <em>6.0M</em>
  • M₂ = unknown
  • V₁ = <em>251 mL</em>
  • V₂ = <em>500. mL</em>

         6.0M\times 251ml=M_2\times 500.ml

Clear M₂ and compute:

         M_2=6.0M\times 251ml/500.ml\approx3.0M
