Ipt Which of the following is true about semipermeable membranes?

Based on the molecular formula, determine whether each of the following is an alkane, alkene, or alkyne. (Assume that the hydroc

stealth61 [152]

Answer:

C₃H₆ is an alkene

C₆H₁₂ is an alkene

C₈H₁₈ is an alkane

C₇H₁₂ is an alkyne

Explanation:

To determine which of the compound is alkane, alkene, or alkyne,we shall use the general formula of alkane, alkene, and alkyne. This is illustrated below:

General formula for alkane => CₙH₂ₙ₊₂

General formula for alkene => CₙH₂ₙ

General formula for alkyne => CₙH₂ₙ₋₂

For C₃H₆:

n = 3

Alkane => CₙH₂ₙ₊₂ => C₃H₂₍₃₎₊₂ => C₃H₈

Alkene => CₙH₂ₙ => C₃H₂₍₃₎ => C₃H₆

Alkyne => CₙH₂ₙ₋₂ => C₃H₂₍₃₎₋₂ => C₃H₄

Thus, C₃H₆ is an alkene

For C₆H₁₂:

n = 6

Alkane => CₙH₂ₙ₊₂ => C₆H₂₍₆₎₊₂ =>C₆H₁₄

Alkene => CₙH₂ₙ => C₆H₂₍₆₎ => C₆H₁₂

Alkyne => CₙH₂ₙ₋₂ => C₆H₂₍₆₎₋₂ => C₆H₁₀

Thus, C₆H₁₂ is an alkene

For C₈H₁₈:

n = 8

Alkane => CₙH₂ₙ₊₂ => C₈H₂₍₈₎₊₂ => C₈H₁₈

Alkene => CₙH₂ₙ => C₈H₂₍₈₎ => C₈H₁₆

Alkyne => CₙH₂ₙ₋₂ => C₈H₂₍₈₎₋₂ => C₈H₁₄

Thus, C₈H₁₈ is an alkane.

For C₇H₁₂:

n = 7

Alkane => CₙH₂ₙ₊₂ => C₇H₂₍₇₎₊₂ => C₇H₁₆

Alkene => CₙH₂ₙ => C₇H₂₍₇₎ => C₇H₁₄

Alkyne => CₙH₂ₙ₋₂ => C₇H₂₍₇₎₋₂ => C₇H₁₂

Thus, C₇H₁₂ is an alkyne.

SUMMARY:

C₃H₆ is an alkene

C₆H₁₂ is an alkene

C₈H₁₈ is an alkane

C₇H₁₂ is an alkyne

1. What was the purpose of creating a sodium bicarbonate solution? What was the purpose of adding soap to the solution?

raketka [301]

Answer:

1. Source of carbon

2. Removal of cuticle

Explanation:

You may have been doing a photosynthesis lab in a biology course.

1. NaHCO₃

The purpose of creating a sodium bicarbonate solution was to provide the carbon that the plant needs for photosynthesis.

2. Soap solution

The soap solution acted as a detergent. It removed some of the waxy, water-repelling cuticle from the leaf's surface and made it easier for the sodium carbonate solution to get inside.

Lab: Thermal Energy Transfer

scoundrel [369]

Answer:

Thermal energy transfers occur in three ways: through conduction, convection, and radiation. When thermal energy is transferred between neighboring molecules that are in contact with one another, this is called conduction.

Can barium ionically bond with kalium

alexgriva [62]

Answer:

NO

Explanation:

Barium cannot ionically bond with Kalium. Kalium is the Latin name for potassium.

Both Barium and potassium are metals. Metals and Metals do not combine to form ionic compounds. Only metals and non-metals form this bond type.

The reason for this is that ionic bond forms by the transfer of electrons from one specie to another that receives it.
Barium is metal and would freely donate electrons to attain stability.
Kalium is metal and shares similar property.

Calculate the percent ionization in each of the following solutions. (a) 0.10 M NH3 WebAssign will check your answer for the cor

Sergeeva-Olga [200]

Answer:

Dissociation NH3 0.10 M : 1.2%

Dissociation NH3 0.010 M : 3.9%

Dissociation CH3NH2 0.10 M : 6.5%

Explanation:

Hello!

To calculate the percentage of dissociation it is necessary:

Pose the balanced chemical equation.

Pose the equilibrium constant.

Calculate the value of "x"

Calculate the percentage of dissociation.

By having the concentrations given two significant figures we express the dissociations with the same amount of significant figures.
