Answer:
Explanation:
The unbalanced nuclear equation is
We can insert the subscripts, because these are the atomic numbers of the elements
That leaves only the superscript of He to be determined,
The main point to remember in balancing nuclear equations is that the sums of the superscripts must be the same on each side of the equation.
Then
27 + x = 31, so x = 31 - 27 = 4
Then, your nuclear equation becomes
Answer:
D. Oxidation
Explanation:
In an <em>electrolytic cell</em>, oxidation (the loss of electrons) takes place at the anode. At the cathode reduction takes place.
A mnemonic technique that could be used is that the process that starts with a vowel (Oxidation) takes place at the place that also starts with a vowel (Anode).
The average atomic mass of N2 is 14.0067. The atomic masses of the 2 stable isotopes of nitrogen, N-14 and N-15, are14.003074002 and 15.00010897 amu, respectively. Calculate the percent abundance of each nitrogen isotope. Ex.: The average atomic weight of copper is 63.5amu .
hope this helps!!!
Answer:
The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. Dispersion forces are present between any two molecules (even polar molecules) when they are almost touching.
Thus <em>PROTON movement causes partial positive & negative charges creating
</em>
<em>attraction</em> will be crrt
