Answer:
The number of neutron in the Aluminium Isotope is :
B. 14
Explanation:
Isotopes : These are the atoms which have same atomic number but have different mass number.
<u>This image shows the average atomic mass of Al element because it is in decimals</u>.
Atomic mass = 26.98154
(Note : mass number of single isotope can never be in decimals)
It is the average of mass of different isotopes of Al
Major Isotopes of
are :
......atomic mass = 26
.......atomic mass = 27
mass of Al given in image(26.98) is nearly equal to mass of 2nd isotope(27)
mass of 
Now calculate the neutron in 
Number of neutron = mass number - atomic number
= 27 - 13
Number of neutron = 14
(Atomic mass is same as mass number)
Answer:
0.6378 M
Explanation:
Molarity is defined by Moles per liter.
Plugging the given information in, we get (14.968 moles)/(23.47 L) which comes out to be about 0.6378 M
large iguanas are affected by el nino temperatures
because algae do not grow as rapidly with el nino temperatures
survival rates for the larger iguanas drop
if they are bigger than 36 centimeters
the drop happens beginning with sizes around 40 centimeters
Answer:
The critical chemical difference is that CO2 contains one atom of carbon and two atoms of oxygen, whilst CO has one carbon and one oxygen atom.
