what are aliphatic alcohols and what differentes it from other alcohols

Answers

Answer 1

Answer: Lipids are one of the important nutrients needed by the body to supply energy and essential fatty acids required by the organism. Solid alcohols are a class of steroids, which are steroids containing hydroxyl groups. Lipids is a general term for oils, fats and lipids. 2, the characteristics are different: fat consists of c, h, o three elements. Fats are triacylglycerides made up of glycerol and fatty acids.

A reaction mixture initially contains 0.236 mol FeS and 0.670 mol HCl. Once the reaction has reached completion, what amount (in moles) of the excess reactant is left

Answers

Answer:

= 0.198 mole H₂S in excess

Explanation:

A quick way to determine limiting reactant is to convert reactant values given to moles and divide by respective coefficient. The smaller value is the limiting reactant other reactants will be in excess. However, when working problem, use mole values given to solve, not results of division.

FeS + 2HCl => FeCl₂ + H₂S

0.236mole/1 0.670mole/2

= 0.236 = 0.335

limiting reactant is FeS; HCl will be in excess.

Problem solution

0.236mole FeS used + 2(0.236 mole HCl used)

=> 0.236 mole FeCl₂ + 0.236 mole H₂S + (0.670 - 0.472) mole HCl in excess or, 0.198 mole H₂S in excess.

All participants in the Genius dog challenge are border collies which some experts think are the what breed of dog?

Answers

As far as the intelligence of canines, it is widely accepted as a fact that the Border Collie is the most intelligent breed of dog.

The conclusion that border collies are the most intelligent breed of dog is credited to a canine psychologist by the name of Stanley Coren. He studied over 138 recognized breeds of dogs to measure the ease with which they learned new commands and the obedience rate of each breed.

Coren studies the learning and obedience of Border Collies over the course of 199 trials and found that this breed of dog performed 95% better than most other breeds, with only 9 of the 138 breeds studied coming close to the results of the border collie. Easily earning the title of the most intelligent breed of dogs.

D) This is a precipitation reaction and 0.83 g of the precipitate will be formed

Answers

Explanation:

no sé de qué me estás hablando

This is a precipitation reaction and 1.38 g of the precipitate will be formed is the statement is correct. Hence, option C is correct.

What is a precipitation reaction?

A precipitation reaction is when two or more dissolved chemicals combine to form one solid products. The exchange of ions between ionic compounds in aqueous solutions is a common component of these reactions, which are also occasionally referred to as double displacement, double replacement, or metathesis reactions.

in response to precipitation a process that converts soluble salts into solids that are insoluble in water. a neutralizing response an interaction between an acid and a base that results in the production of salt, water, and an ionic molecule.

Precipitate refers to a solid that forms from a solution. The blending of two transparent solutions is a common example: NaCl in combination with silver nitrate The answer is. The soli cannot be dissolved in water.

Thus, option C is correct.

Which best explains why nanofiltration is an important new technology?

A. It can be used to help regions that have a short supply of usable water.
B. It can be used as an energy source to produce electricity in regions with limited coal.
C. It recycles wastewater to be reused for geothermal energy.
D. It collects solar energy to generate electrical power.

Answers

Explanation:

Our Direct Nanofiltration (dNF) membranes offer the unique combination of a low fouling hollow fiber configuration with the ability to remove organics and salinity (hardness) from water in one simple step. Other than a strainer, no further pre-treatment is required. We manufacture our membranes with a patented layer-by-layer process, where multiple nano-scale layers are deposited on a membrane support. This method enables very precise and controlled rejection and flux properties of the membrane. A unique solution for troubled water.

2. What is the temperature (°C) of 1.50 moles of gas stored in a 10.0 L container at 1558 mm
Hg? (R=0.082 L atm/ mol K, 1.00 atm = 760 mm Hg
(4 points)

Answers

Answer:

-106°C

Explanation:

1558 mmHg / 1 × 1 atm / 760. mmHg = 2.05 atm

PV = nRT

2.05 atm (10.0 L) = 1.50 mol (0.082 atmL/molK) T

20.5 atmL = (0.123 atmL/K) T

K/0.123 atm L × 20.5 atmL = (0.123 atmL/K) T × K/0.123 atmL

166.666 K = T

167 K = T (sig figs)

K = °C + 273

167 - 273 = °C - 273

-106 = °C

Answers

Answer:

Answer:

Explanation:

The answer is B. All hydrocarbons are nonpolar, they are insoluble in water and they are highly flammable. Now, not all hydrocarbons have high boiling and melting point. For example, methane (CH4) has a boiling point of something clode to -161°C, and that is low. The boiling point increases when the number of carbon atoms in a compound increases, and based on methane and this theory, not all hydrocarbond have a high boiling point. This makes option B be the correct answer.

Did all the silver ions get consumed in the reaction? The molar mass of silver is 107.87 g/mol. Justify your answer.

Answers

This problem is asking for the consumption of silver ions when silver nitrate is reacted with copper. In such a case, since no masses are given, we can use the following from similar problems:

Mass of empty beaker: 110.000 g

Mass of beaker with silver nitrate (after all additions) and copper: 331.634 g.

Mass of beaker with silver: 113.395 g.

This means we can write the following chemical equation:

[tex]Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag[/tex]

And thus calculate the mass of silver nitrate that will produce the following mass of silver:

[tex]m_{Ag}^{produced}=113.395g-110.000g=3.395g[/tex]

The molarity of the Ca(NO3)2 solution would be 0.005 M

First, let us look at the balanced equation of the reaction:

[tex]2HNO_3+Ca(OH)_2 ---> Ca(NO_3)_2+2H_2O[/tex]

The mole ratio of HNO3 to Ca(OH)2 is 2:1.

Mole of HNO3 = molarity x volume

= 0.2 x 150/1000

= 0.03 mole

Mole of Ca(OH)2 = 0.01 x 150/1000

= 0.0015

Thus, there is no limiting or excess reactant.

Also from the equation, mole ratio of Ca(OH)2 to Ca(NO3)2 is 1:1. Hence, the mole of Ca(NO3)2 would also be 0.0015 mole.

The total volume of the resulting solution would be: 150 +150 = 300 mL

Thus, the molarity of the resulting Ca(NO3)2 would be:

Molarity = mole/volume

= 0.0015/0.3

= 0.005 M

Glucose is a molecular substance therefore, there are no ionic species in glucose.

Ionic substances dissolve in water to yield ions. Molecular substances do not produce ions in solution. The conductivity of ionic solutions owes to the presence of ions in solutions. Molecular solutions do not conduct electricity due to the absence of ions.
