-Ionic bonds lose or gain electrons usually between a non-metal and a metal,
-Covalent bonds share electrons usually between two non-metals
They would collapse as the sun gives the producers energy to grow i.e plants through photosynthesis. Without plants most animals would die out unless humans could somehow create a food in labs without animals or plants for 6 billion people. Ultimately it would be the death of the human race and just about everything on Earth apart from some plants that live in the deep depths of the sea which have adapted to not having as much sunlight.
Answer: E = (13.6 eV) [1/nf² - 1/ni²]
En = (-13.6 eV)/n²
where n=1,2,3...
Explanation:
According to Bohr's theory each spcified energy value( E1,E2,E3...) is called energy level of the atom and the only allowable values are given by the equation
En = (-13.6 eV)/n²
The energy change (ΔE) that accompaies the leap of an electron from one energy level to another is given by equation
E = (13.6 eV) [1/nf² - 1/ni²]
Answer:
Brass is an alloy, and either a "solid solution".
Alloys in general may be solid solutions or they simply be mixtures

Mass (g) / Volume (cm^3) = Density (g/cm^3)
60.4g/ 11.3 cm^3 = 5.35 g/cm^3
d= 5.35 g/cm^3
