the answer to your question is radium
Answer:
8025.996 grams are there in 3.26*10²⁵ Molecules of Mg(NO₃)₂.
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023*10²³ molecules are contained in 1 mole of the compound, 3.26*10²⁵ molecules are contained in how many moles of the compound?
![amount of moles=\frac{3.26*10^{25}molecules*1 mole }{6.023*10^{23}molecules }](https://tex.z-dn.net/?f=amount%20of%20moles%3D%5Cfrac%7B3.26%2A10%5E%7B25%7Dmolecules%2A1%20mole%20%7D%7B6.023%2A10%5E%7B23%7Dmolecules%20%7D)
amount of moles= 54.12
Molar mass is the mass of one mole of a substance, which can be an element or a compound. Being the molar mass of the compound Mg(NO₃)₂ 148.3 g/mole, so 54.12 moles of the compound contains 8025.996 grams.

Answer would be c! hope i can help
Answer:Free radical mono-halogenation of an alkane is typically conducted using bromine versus chlorine because the bromine radical is less reactive and therefore more selective.
Explanation: Halogenation occurs when a halogen replaces one or more hydrogen atoms in an organic compound ie chlorine or bromine with the reactivity of the halogens decreasing in the order of F2 > Cl2 > Br2 > I2
Since fluorine reacts explosively making it is difficult to control, and iodine is unreactive. Free radical mono-halogenation of an alkane is typically conducted using bromine versus chlorine with Chlorination ie chlorine radical being more reactive and not selective and the Bromination of alkanes ie bromine radical occurring similarly but slower and less reactive but more selective which is due to the fact that a bromine atom is less reactive in the hydrogen abstraction than a chlorine atom evidence in the higher bond energy of H-Cl than H-Br.
