The balanced reaction between Hydrogen and Oxygen to form Water:
2H₂ + O₂ → 2H₂O
From the equation it already states that:
2 molecules of Hydrogen H₂ are needed to produce 2 molecules of Water H₂O
So the answer is 2.
Option B.
Answer:
The statements that describe sunspots is;
D. Sunspots have lower temperatures than their surroundings
Explanation:
Sunspots is a phenomenon that involves temporary appearance of dark areas on the Sun's surface, which are regions of concentrated magnetic field flux which inhibit heat transfer by convection and are therefore cooler than other parts of the Sun. Due to the presence of magnetic field magnetic
Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Opposite magnetic polarity sunspots usually appear as a pair.
Therefore, the statement that best describe sunspots is that a sunspot is a region of reduced temperature compared to surrounding areas on the Sun's surface.
The compound that was formed by the reaction of the first oxygen released by Cyanobacteria and iron are the metals of the earths crust. Cyanobacteria was the first organisms that used water instead of hydrogen sulfide or other compounds as a source of electrons and hydrogen for fixing carbon dioxide. Early Cyanobacteria inhabited marine sediments where Archean banded iron formations were deposited; consisting of reddish layers rich in iron oxide.
