Molar mass details
10.81B (1*10.81)
Hope this helps
The answer is the chemical structure and the temperature
Answer:
, zirconium-103.
Explanation:
In a nuclear reaction, both the mass number and atomic number will conserve.
Let
represent the unknown particle.
The mass number of a particle is the number on the upper-left corner. The atomic number of a particle is the number on its lower-left corner under the mass number. For example, for the particle
,
is the mass number while
while
is the atomic number.
Sum of mass numbers on the left-hand side of the equation:
.
Note that there are three neutrons on the right-hand side of the equation. Sum of mass numbers on the right-hand side:
.
Mass number conserves. As a result,
.
Solve this equation for
:
.
Among the five choices, the only particle with a mass number of 103 is
. Make sure that atomic number also conserves.
Chlorine<span> is in group 17 of periodic table, also called the halogens, and is not found as the element in nature only as a compound.
