Predict the major product of the following reaction of 1-methylcyclohexene with dilute HCl in H2O?
Scrat [10]

Answer:

1-chloro-1-methylcyclohexane

Explanation:

The hydrocarbons with one double bond are called alkenes and are named with the suffix "ene". The alkenes, such as 1-methylcyclohexene, react better in an addition reaction. The double bond will be broken, and the substitutes will be placed at them.

In the reaction with HCl, H and Cl will be added to the carbons of the broken bond. The major product is formed when H is put at the carbon less substituted. Thus, the product will be the one given below, 1-chloro-1-methylcyclohexane.

Which of the following sets of units could be appropriate for a zero-order rate constant?Answers-1L mol-1 s-1L2 mol-2 s-1L3 mol-
mars1129 [50]

Answer:

mol·L⁻¹·s⁻¹

Explanation:

In the case of a <em>zero-order reaction</em>, the reaction rate does not change with the decrease or increase in the concentrations of the reactants:

  • rate = k

And because the rate must have units of mol·L⁻¹·s⁻¹, then the rate constant <em>k</em> must also have units of mol·L⁻¹·s⁻¹.

25.0 mL of an LiOH solution were titrated with 29.15 mLof a 0.205 M H3PO4 solution to reach the equivalence point. What is the m
borishaifa [10]

Answer:

0.717 M LiOH

Explanation:

(Step 1)

Calculate the moles of H₃PO₄ using the molarity equation.

29.15 mL / 1,000 = 0.02915 L

Molarity = moles / volume (L)

0.205 M = moles / 0.02915 L

0.00598 = moles

(Step 2)

Convert moles H₃PO₄ to moles LiOH using the mole-to-mole ratio from reaction coefficients.

1 H₃PO₄ + 3 LiOH -----> Li₃PO₄ + 3 H₂O
^                ^

0.00598 moles H₃PO₄            3 moles LiOH
------------------------------------  x  --------------------------  =  0.0179 moles LiOH
                                                  1 mole H₃PO₄

(Step 3)

Calculate the molarity of LiOH using the molarity equation.

25.0 mL / 1,000 = 0.0250 L

Molarity = moles / volume (L)

Molarity = 0.0179 moles / 0.0250 L

Molarity = 0.717 M
