Answer:
Explanation:
Your nuclear equation is
The main point to remember in balancing nuclear equations is that
- the sum of the superscripts and must be the same on each side of the equation.
- the sum of the subscripts must be the same on each side of the equation.
Then
85 = 0 + y, so y = 85 - 0 = 0
35 = -1 + x, so x = 35 + 1 = 36
The nucleus with atomic number 36 and atomic mass 85 is krypton-85.
The nuclear equation becomes
Multiply 90 by 1,609.344: 144,840.96 meters :)
Answer:
Bonds are polar when one element in a compound is more electronegative than the other. This creates a dipole in the molecule where one end of the molecule is partially positive and one end is partially negative
Explanation:
Answer:
1.772 mols
Explanation:
Because hydrogen exists as a diatomic molecule in gaseous state, that's (H2), so then it's molecular mass is 1 ×2= 2g/mol.
we can now calculate for the number of moles, so
n=m/Mr
n=3.544/2
n=1.772mols
What are the calculation like answer
