Answer:
The answer is C. 4 Hydrogen atoms.
Explanation:
Four hydrogen atoms can make a bond with one carbon atom so that it is stable i.e., it attains a noble gas configuration. As in methane CH4.
Hope this helps :)
Answer:
C. 4
Explanation:
Carbon has four electrons in its valence (outermost) electron shell. Therefore, it will form covalent bonds with four hydrogen atoms.
Where do light bulbs get their energy from?
Answer:
Light bulbs gets the energy from electricity which makes it light up.
Which of the following evidence supports the theory of plate tectonics?
The age of rocks and mountains on the edge of neighboring continents varies.
Fossils from the same species are found on only one continent.
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
Grooves created from glacier movement travel in opposite directions on each continent.
The characteristics of the tectonic plates allows to find the result for the correct statement is:
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
The tectonic plate model establishes that by the hot magma convection currents the solid crust breaks in the weakest areas, forming plates that move floating on this, hot magna that can rise through the cracks and separate these plates.
In the attached we see a diagram of the magnetic alignments in the rocks from a tectonic plate, we can see that the alignment changes due to the inversion of the earth's magnetic field in such a way that we can appreciate the separation of the two plates.
Another proof is that other similar animals are on continents separated by great distances.
Let's analyze the different claims:
a. False. Radioactive dating evidence gives that the rocks give that the rocks on the two continents are the same age.
b. False. Fossils of the same spice are found on several continents.
c. True. These rocks when they emerged were aligned and when moving and the magnetic field reversed the rocks are no longer aligned, this is one of the greatest proof of the separation of tectonic plates.
d. False. The furrows of the glaciers go from the North to the South, it does not have the direction of the displacement of the plates.
In consequence of the characteristics of the tectonic plates we can find the result for the correct statement is:
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
