Answer:

t-butyl cation

Explanation:

Generally a dehydration reaction occurs when an organic compound loses  water molecules to form alkenes. However, in an acid-catalyzed dehydration, the dehydration reaction occurs in the presence of an acidic compound which acts as a catalyst. Therefore, for this specific case, the hydride will migrate and a t-butyl cation will be formed.  This is because it is more stable due to the presence of three electron releasing alkyl groups which can stabilize a positive charge compared with the secondary cation formed when the methyl group migrates.

What volume of so2 is produced at 325 k and 1.35 atm when 15.0 grams of hcl reacts with excess k2so3?
Helen [10]
The balanced equation for the above reaction is as follows;
2HCl + K₂SO₃ ---> 2KCl + H₂O + SO₂
stoichiometry of HCl to SO₂ is 2:1
number of moles of HCl reacted - 15.0 g / 36.5 g/mol = 0.411 mol 
according to molar ratio 
number of SO₂ moles formed - 0.411 mol /2 = 0.206 mol
since we know the number of moles we can find volume using ideal gas law equation 
PV = nRT
where
 P - pressure - 1.35 atm x 101 325 Pa/atm = 136 789 Pa 
V - volume 
n - number of moles - 0.206 mol 
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 325 K
substituting values in the equation 

136 789 Pa x V = 0.206 mol x 8.314 Jmol⁻¹K⁻¹ x 325 K 
V = 4.07 L 
volume of SO₂ formed is 4.07 L

Identify whether the description refers to a monomer, a polymer, or both. Macromolecule:
larisa86 [58]

Answer:

Macromolecule: polymer

Repeating units: monomer

Simple molecule: monomer

Covalent bonds: both

Explanation:

A macromolecule is a very large molecule commonly created by the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more.

A  monomer is a molecule that can be reacted together with other monomer molecules to form a larger polymer chain.

Polymers include bounds between nonmetal atoms, therefore, they are joint by covalent bonds
