If we have a neutral atom, then it has the same number protons and neutrons.
The number protons and neutrons for neutral atom shows atomic number.
"A neutral atom has an atomic number of 20" means that atom has 20 protons (that give charge "+ 20" ) and 20 electrons (that give charge "-20").
Answer is 20 electrons.
Answer:
dCDP
Explanation:
The nucleotide has hydrogen at it second carbon which means that it has deoxy pentose sugar which is written in small d as prefix.
The nitrogenous base is cytosine and it contains 2 phosphate groups which are attached to the 5 carbon of the pentose sugar means it is cytosine diphosphate.
<u>So, the abbrevation of the molecule is : dCDP</u>
The sequence of coefficient that should be placed in the blank space to balance ii as follows
the sequence is 2 infront of Al 3 infront of O2 and 2 infront of Al2O3
that is 2Al +3O2 = 2Al2O3
from equation above 2 moles of Al reacted with 3 moles of O2 to form 2 moles of Al2O3
CH4 is the molecular formula for methane.
