Answer:
Energy of an electron is quantinized means the electrons can possess only specific individually separated values.
These energy levels are stable and are stationary along with different energy value. The electron remains in the state until energy is absorbed or released.
The electrons absorb energy when it moves from lower energy state to higher energy state. The electrons lose energy when it moves from higher energy state to lower energy state and thus emit radiations corresponding to the energy gap and is called as quanta.
Answer:
Coccus and Bacillus
Explanation:
bacillus means bacteria in thread-like structure and coccus -spherical in shape. these are the most common shapes of bacteria other like streptococcus, staphylococcus, etc are formed from the combination of the above.
Answer:
Ductility
Explanation:
Ductility is the ability of a metal to be converted into a thin wire without getting break and loosing its hardness. The property of Ductility of a metal allows us to make a wider use of them. Some most ductile metals are gold, silver, copper etc. whereas some of the metals with very less ductility are tungsten, steel and other alloys as they are very hard to transform into a thin wire.
A metal with less ductility can be malleable as it can have the ability to be converted into a thin sheet. Not all the metals are ductile but some of them have high ductility, some have less and some of them are non ductile.
HCl is a strong base therefore it completely dissociates to H⁺ and Cl⁻ ions.
To calculate pH we need to know [H⁺]
number of HCl moles in 50.0 mL - 0.200 M /1000 mL/L x 50.0 mL = 0.01 mol
concentration of HCl - 0.01 mol/0.1 L = 0.1 M
[HCl] = [H⁺] due to complete dissociation
pH = -log [H⁺]
pH = -log (0.1 M)
pH = 1
pH of the solution is 1
Answer: FALSE
Tides and Water Levels
Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996). ... Our sun is 27 million times larger than our moon.
