Answer:
Manganese is the name and symbol of the element is Mn.
Explanation:
Charge of the mono-atomic ion = 2+
Atomic mass of the nucleus = 55
Atomic mass =Number of protons + Number of neutrons
Given that :
Number of neutrons = 1.2 (Number of protons)
n = 1.2 × p
p = 25
Atomic number is equal to Number of total protons in the nucleus.
The atomic number of an element is 25 which Manganese with symbol 'Mn'.
Answer:
the change of NH3 conversion with temperature and 02 amount without H2 at atmospheric pressure and 800ppm inlet HN3 concentration:...
The working equation for this problem is average atomic mass
is equal to the summation of the product of relative abundance and mass of
isotope. In this problem, just subtract the % abundance of Ag-107 to 100. Thus
the % abundance of Ag-109 is 48.16.
Forensic scientists can compare DNA found at a crime scene (from blood or hair, for example) to DNA samples taken from suspects. If there is no match, they may be able to rule out that suspect. If there is a match, police will likely want to take a closer look.
GROUNDWATER is the term used for water that soak into the ground, fills the openings in the soil and trickles into cracks and spaces in rock layers.
Groundwater is usually found underneath the earth surface in the spaces and cracks in sand, rock and soil. It is stored in aquifers. Ground water usually connect with various water bodies such as oceans, rivers and streams and it is always a natural source of water for vegetation. Ground water is a very important natural resource.
