Energy= 2381 joules
heat= Mass(kg) *change in temperature(K) * Cp
2381=0.155*(15)*Cp
Cp=1024 J/kg K
Calcium chloride forms an ionic compound with a
regularly arranged lattice of oppositely charged ions.
The Na+ and Cl- ions are held together by
strong electrostatic forces.
Hope that helps
Answer:
A collapse of the population is rotting, food is not enough and livelihoods have become unfeasible to decrease the number of individuals again.
Another way is to generate mutations to generate a species more vulnerable to decreasing numbers.
In this way the overpopulation is controlled.
Explanation:
In ecosystems, if an increased population breaks the balance of this and begins a new constant adaptation of the extinction of some and overpopulation of others, which may be some chains break or remain unstable.
B. released, forming bonds usually releases energy.
Answer:
This is all true if the atom has to be neutral.
Also what does V mean?
Helium: one shell with 2 neutrons and 2 protons in the center, with 2 electrons in the first shell.
Lithium: two shells with 4 neutrons and 3 protons in the center, with 2 electrons in the first shell, and 1 electron in the second shell.
Nitrogen: two shells with 7 neutrons and 7 protons in the center, with 2 electrons in the first shell, and 5 electrons in the second shell.
Flourine: two shells with 9 protons and 10 neutrons in the center, with 2 electrons in the first shell, and 7 electrons in the second shell.
