Answer:
The correct answer is option (B) Two molecules of H2 and a molecule of O2 must collide at one time
Explanation:
2H2(g) + O2(g) → 2 H2O(g)
2 1 2
Considering the given reaction, for water molecule to be form, two molecules of hydrogen and one molecule of oxygen must collide at the same time. The product obtained from the collision is two molecules of water as steam. 2 H2O(g)

Sea level may rise as a result of the expansion of seawater and the melting of land-based ice due to a warming environment.
<h3>What is the sea level?</h3>
The sea level is the fundamental level for calculating height and depth on Earth. Since the ocean is one continuous body of water, its surface tends to seek a constant level. The sea surface is not actually level due to winds, currents, river discharges, fluctuations in gravity, and temperature.
<h3>Why is sea level important?</h3>
People are impacted by sea level changes through flooding, the inability of rivers to empty into the ocean due to the sea being too high, and the surge of seawater onto the land during storms. Our drinking water and the ability to cultivate crops could be harmed if sea water gets into farms and reservoirs.

Answer:
it is heterotrophic. it is unicellular. it does not have a nucleus.
Explanation:
The quantum mechanical model is used to describe the energy and most likely location of an electron.
Answer: Option A
<u>Explanation:
</u>
The quantum mechanical model leads to the introduction of quantum numbers representing the energy levels, sub-shells, orbitals as well as spin states of the electrons. So according to the quantum numbers we can perfectly define the position and energy of any electron in an element.
According to Pauli’s principle, any two electron cannot be having same set of quantum numbers. So, using the principle quantum number, azimuthal quantum number, magnetic and spin quantum number, we can define the energy and location of an electron in the atom.
