Arrange the liquids ethanol (C2H5OH), glycerol [HOCH2CH(OH)CH2OH], and ethylene glycol (CH2OH)2 in decreasing order of expected viscosities.

Answers

Answer 1

The decreasing order of viscosity of the given liquids is as glycerol, ethylene glycol, and ethanol.

Viscosity is the resistance of a fluid to change shape or flow when compared to other liquids. So the fluid with high viscosity will have low fluidity. The main reason for increased viscosity will be due to the molecular interactions . Viscosity can also be defined as the ease with which the molecules can move concerning one another. That means the more the interaction between molecules, the more viscosity.

In the case of the given liquids, all have OH groups, which could result in hydrogen bonding. So more the hydroxyl groups, the more the hydrogen bonding, the more interaction, and high the viscosity. Here glycerol has three OH groups, So it will have the highest viscosity. The ethylene glycol with two OH groups comes second and then ethanol.

So the decreasing order of viscosity will be, Glycerol, Ethylene glycol, and Ethanol.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

For the rxn CaCo3(s)+2Hcl(aq)_CaCl(aq)+Ca2(g)+H2O(l)68.1 g solid CaCo3 is mixed with 51.6Hcl what number of grams of Co2 will be produced

Answers

Answer:

29.9 g of CO₂ will be produced by the reaction.

Explanation:

This is the reaction:

CaCO₃(s)  + 2HCl (aq)  →  CaCl₂(aq)  + CO₂(g) +  H₂O(l)

First of all, we state the moles of each reactant:

68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate

51.6 g . 1 mol/36.45g = 1.46 mol of acid.

The solid salt is the limiting reactant. Ratio is 2:1

2 moles of acid can react to 1 mol of salt

1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles

As we only have 0.680 moles of salt, we do not have enough.

Let's work at the product side. Ratio is 1:1

1 mo of salt can produce 1 mol of gas

0.680 moles will produce 0.680 moles of gas

We convert the moles to mass → 0.680 mol . 44g / 1mol = 29.9 g of CO₂

The number of grams of Co2 should be produced is 29.9 g.

Calculation of the number of grams:

Since

CaCO₃(s)  + 2HCl (aq)  →  CaCl₂(aq)  + CO₂(g) +  H₂O(l)

So,

68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate

51.6 g . 1 mol/36.45g = 1.46 mol of acid.

Now the ratio should be 2:1 for the solid salt

And, there is 2 moles of acid can react to 1 mol of salt

So,

1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles

Now the product side the ratio is 1:1

So, that means

1 mo of salt can produce 1 mol of gas

So, the no of grams should be

= 0.680 mol . 44g / 1mol

= 29.9 g of CO₂
