Answer:

<h2>Loess.</h2>

Explanation:

Remember that sediment is natural material broken by erosion process on the surface. That's why the answer cannot be clay, if you thought about it.

So, loess is sedimentary deposits, it's like clay, but finest.

Consider the following four structures: What is the relationship of I and II? What is the relationship of I and III? What is the

daser333 [38]

Answer:

The different structures are shown in the attachment.

I and II - structural isomers

I and III - Structural isomers

I and IV - structural isomers

II and III - structural isomers

II and IV - structural isomers

III and IV - stereoisomers

Explanation:

The knowledge of Isomerism is tested here; there are two types of isomerism ; structural and stereoisomerism.

Structural Isomers have similar molecular and different double bond positioning, these occurs mostly in ALKENE FAMILY.

Stereo-isomers have the same molecular formular and similar patterns but differ in their spatial arrangement. trans and cis are typical examples of stereo-isomers.

From the question; Relationship between I and II is that they are structural isomers since they have the same molecular formula, but different bond atom arrangement and infact they are the same compound.

Relationship between I and III is that they are structural isomers with similar molecular formular but differ in the double bond position.

Relationship between I and IV is that they are structural isomers with similar molecular formula but different double bond arrangement.

Relationship between II and III is that they are structural isomers with similar molecular formular but different double bond position

Relationship between II and IV is that they are also structural isomers with the same molecular formular but different double bond position.

Relationship between III and IV is that they are stereo-isomers with same molecular formula but different spatial arrangement, hence cis and trans.

Identify the species that was reduced in the titration reaction. Justify answer in terms of oxidation number 6h+(aq)+2mno4−(aq)+

egoroff_w [7]

Answer:

Explanation:

Reaction given

6 H⁺ + 2 MnO₄⁻ + 5 (COOH)₂ = 10CO₂ +8H₂O + 2 Mn⁺²

Oxidation number of Mn in MnO₄⁻

= x - 4 x 2 = -1

x = 8 -1

+ 7

Oxidation no of Mn in Mn⁺² = +2

So its oxidation no is decreased from + 7 to + 2 . Hence it is reduced.

An antacid tablet with an active ingredient of CaCO3 was dissolved in 50.0 mL of 0.300 M HCl. When this solution was titrated wi

yaroslaw [1]

Answer:

Explanation:

mole of HCl remaining after reaction with CaCO₃

= .3 M of NaOH of 32.47 mL

= .3 x .03247 moles

= .009741 moles

Initial HCl taken = .3 x .005 moles = .0015 moles

Moles of HCl reacted with CaCO₃

= .009741 - .0015 = .008241 moles

CaCO₃ + 2HCl = CaCl₂ + CO₂ + H₂O .

1 mole 2 moles

2 moles of HCl reacts with 1 mole of CaCO₃

.008241 moles of HCl reacts with .5 x .008241 moles of CaCO₃

CaCO₃ reacted with HCl = .5 x .008241 = .00412 moles

the mass (in grams) of calcium carbonate in the tablet

= .00412 x 100 = .412 grams . ( molar mass of calcium carbonate = 100 )

How many atoms are in a sample of 0.75 moles of carbon atoms

vova2212 [387]

Answer: 4.5165 *10^-23 moles Carbon

Explanation:

There are 6.022*10^23 atoms in a mole.

Therefore, there would be 6.022*10^-23*0.75 atoms in 0.75 moles of Carbon.

= 4.5165 *10^-23 moles Carbon

____ [38]

Explanation: Process is diffusion. The gas molecules follow a zig-zag path through the tube as they collide with the air molecules in the tube. The purpose of the glass tube is to eliminate air currents and to see if the gas molecules will move on their own.
