I'm pretty sure it's 9726 milligrams of iodine. Hope this helps.
Elements that there Electrons equal a multiple of 8 because then they become a noble gas.
A polar aprotic solvent is a polar solvent that does not have a hydrogen atom.
A polar protic solvent is a solvent that contains hydrogen. Water, ethanol and acetic acid are all examples of a polar protic solvent. A polar aprotic solvent is a polar solvent that does not contain hydrogen. Dimethyl sulphoxide, acetonitrile and dichloromethane are all examples of polar aprotic solvents.
The following are true about polar aprotic solvent.
- Acetone is a polar aprotic solvent because it cannot act as a hydrogen-bond donor.
- A polar aprotic solvent solvates cations by ion-dipole interactions.
Polar aprotic solvents solvates cations because the negative end of the dipole can interact well with the cation. Polar aprotic solvents interacts with ions by ion - dipole interaction.

The answer would be B. Liquid
Answer: A catalyst is a substance that speeds up the rate of a chemical reaction without being used up and remains chemically unchanged itself .
Explanation: For a reaction to take place the particles must collide with enough energy for bonds to break and reaction to occur .
BUT when a catalyst is present the reactants are able to react in a way that requires less energy ,leading to more successful collision so the reaction speeds up without the chemical composition of the catalyst being affected
NOTE: the catalyst must be chosen to suit the particular reaction
