I think that the empirical formula is mgcl2
Radioisotopes are used to study chemical reactions because of the fact that they attach radioactive isotopes to certain atoms.<span> Tracer radioisotopes used to study chemical reactions in molecular structures by adding radioistopes to reactants and using the uptake compared to the original isotope. </span>
A. gas change, color change, and temperature change.
B. color change; one day you wore a ring that wasn't stainless steel in the shower, so the following morning it was rusted.
When the molecule undergoes chlorination with Cl2 on heating, the hydrogen atom of the alkyl group is replaced by the chlorine atom and form chloroalkanes. The molecule X containes three types of alkyl halides, therefore three different types of chloroalkanes are formed by the replacement of hydrogem atom linked to these alkyl groups. Thus the three different types of chloroalkanes are formed - primary, secondary, and thertiary chloroalkane. Chlorination is not selective so a mixture pf products results. The products formed by the reaction of the molecule with Y with Cl2 are shown on the attached file.
The molarity of the solution is 0.260 M
<u><em>calculation</em></u>
step 1: calculate the moles of NaOH
moles = mass÷ molar mas
= 5.20 g÷ 40.00 g/mol= 0.13 moles
Step 2: find the molarity of solution
molarity = moles÷volume in liters
=0.13 moles÷ 0.500 L = 0.260 M
