Answer:
8 oxygen. 9 flourine. 10. Neon. 5 Boron
Answer:
Places where primary succession occurs include newly exposed rock areas, sand dunes, and lava flows. Simple species that can tolerate the often- harsh environment become established first. These organisms help enrich the soil, allowing other species to become established.
Image result for think about succession and the places you have seen or visited. choose one place, provide evidence from your experience, to determine whether your example showed primary or secondary succession. you can write and/or include pictures
For example, after a forest fire that kills all the mature trees on a particular landscape, grasses might grow, followed by shrubs and a variety of tree species, until eventually the community that existed before the fire is present again
Answer:
The scientific method is a method of research in which a problem is identified, relevant data are gathered. Also hypothesis is made from this data, and the hypothesis is empirically tested.
Explanation:
Answer:
If we increase the temperature, the average kinetic energy increases, and that means the molecules are more likely to have enough kinetic energy to go into or stay in the gas phase. (Thus, they are called intermolecular forces, to separate them from the forces inside molecules that hold the molecules together.)
Explanation:
here you go:)
Half reaction :
Oxidation
Cu ⇒ Cu²⁺ + 2e⁻
Reduction
2Ag⁺+ 2e⁻ ⇒2Ag
<h3>Further explanation</h3>
Given
Reaction
Cu+2AgNO₃⇒Cu(NO₃)₂+2Ag
Required
Oxidation and reduction half-reactions
Solution
Oxidation is an increase in oxidation number, while reduction is a decrease in oxidation number.
Cu ⇒ Cu²⁺ + 2e⁻
0 to +2
2Ag⁺+ 2e⁻ ⇒2Ag
+1 to 0
