A certain intermolecular force is created due to a brief concentration of electrons between nonpolar molecules. What best explai

ns the strength of this intermolecular force?
A. Very strong, because it is a result of interactions between highly polar molecules

B. Weak because it is a result of the interaction between ions and polarized molecules

C. Very strong because it is a result of interactions between symmetrical molecules causing canceling of dipoles

D. Weak because it is a result of interactions between molecules with instantaneous dipoles

Answer:

The correct answer is D

Explanation:

Many substances hold their molecules together in the liquid or solid bosom. This is due, in addition to the pressure and temperature conditions, by the forces of Van der Waals. These are still produced in nonpolar molecules by the movement of electrons through the molecules; in extremely short periods of time, their electrons "charge" towards one end of the molecule, producing small dipoles and keeping the molecules very close to each other.

An organic compound of relative molecular mass 46,on analysis was found to contain 52.0% carbon, 13.3% hydrogen and 34.7% oxygen
Nadya [2.5K]

Answer:

Empirical formula is C₂H₆O.

Explanation:

Empirical formula:

It is the simplest formula gives the ratio of atoms of different elements in small whole number

Given data:

Percentage of hydrogen = 13.3%

Percentage of carbon = 52.0%

Percentage of oxygen = 34.7%

Empirical formula = ?

Molecular formula = ?

Solution:

Number of gram atoms of H = 13.3 / 1.01 = 13 .17

Number of gram atoms of O = 34.7 / 16 = 2.17

Number of gram atoms of C = 52.0 / 12 = 4.3

Atomic ratio:

            C                     :          H             :           O

           4.3/2.17            :     13.17/2.17     :       2.17/2.17

            2                      :        6               :        1

C : H : O = 2 : 6 : 1

Empirical formula is C₂H₆O.

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

n = 46 / 158

The relative molecular mass of compound is not correct.

What is the theoretical yield of waffles if you have 6 cups of flour, 9 eggs and 2 tbs of oil?
Yanka [14]

Answer:

8 waffles

Explanation:

First, find the limiting reagent.  Divide the amount you have by the amount that is needed.  The smallest number is the limiting reagent.  <u>For this problem, the limiting reagent is oil.</u>

6 cups of flour/2 cups of flour = 3

9 eggs/3 eggs = 3             2 tbsp of oil/1 tbsp of oil = 2

This means that we can double the recipe since we have enough of each ingredient to make two batches.  Multiply the entire equation by 2.  This should give you   4 cups of flour  +  6 eggs  +  2 tbsp of oil  ==>  8 waffles.

<u>You should theoretically get 8 waffles.</u>

A 12.8 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter with a heat capacity of 5.65 kJ/°C. Using the information be
Yanka [14]
To answer the question above, we need to c<span>onvert 12.8 g to moles by dividing by 46.07 first.</span>

<span>For every mole you burn, you get 1235 kJ of heat. So multiply your number of moles by 1235. It'll be something in the neighborhood of 500. </span>

<span>Take your kJ that you calculated and divide by 5.65 to get the number of degrees that your calorimeter goes up. Add that to 25.

I hope my answer helped you</span>
