Law of cross-cutting relationships

Explanation:

This interpretation is based on the law of cross - cutting relationships.

This law states that "faults and fractures that cuts through a rock are younger than the rocks they cut through".

Answer:

Ionic or electrovalent bonds

Explanation:

The bond type that will result when the two atoms combine is an electrovalent or ionic bond. This is due to the large  electronegativity difference between the given species.

The type of bond that will result if the atom Cs and F combine will be an electrovalent bond or ionic bond.

From the given atom, Caesium Cs with an electronegativity of 0.79 is a Group 1 metal which is an alkali metal.

Fluorine F with electronegativity 4.0 is a member of the halogen family.

An Electrovalent bond or ionic bond is a type of bonding reaction that occurs between group 1 metals and group 7 elements due to the high difference in their electronegativities.

Therefore, Cs and F form CsF via electrovalent bonding or ionic bonding with one another.

Answer:

Mesozoic - the era before the current one

Cenozoic - the current era

Paleozoic - when life first flourished

Precambrian - the first era

Explanation:

The Precambrian is the earliest part of Earth's history, the first era. It's named like this because it preceded the Cambrian - the first period of the Phanerozoic eon, which is the current geologic eon. It lasted from the beginning of Earth (about 4.6 billion years ago) to the beginning of the Cambrian Period (about 541 million years ago).

Paleozoic is an era that lasted from about 541 to about 252 million years ago. During this time, life began to flourish.

Mesozoic is an era that lasted from about 252 to 65 million years ago. It's the era that took place before the current one - the Cenozoic.

Answer:

d = 1.8 g/mL

Explanation:

Given data:

Mass of bottle = 6.8 g

Volume of liquid = 23.1 mL

Mass of bottle + liquid = 48.8 g

Density of liquid = ?

Solution:

First of all we will calculate the mass of liquid.

Mass of liquid = combined mass - mass of bottle

Mass of liquid = 48.8 g - 6.8 g

Mass of liquid = 42 g

Density of liquid:

d = m/v

d = 42 g/ 23.1 mL

d = 1.8 g/mL

A is the correct answer

Answer:

The correct option is C.

The respiratory and digestive systems work together

to make usable ATP energy for cells.

Explanation:

DIGESTIVE SYSTEM is the System the body that help to breakdown compound molecules into smaller pieces that can easily by absorbed by the body hence release nutrients and ATP. Energy are stored as glucose and resuable as ATP.

RESPIRATION is a process whereby oxygen is inhaled and it help to breakdown large compounds to release energy (ATP) and carbon dioxide is released. Both system work together to release ATP for cells.

Therefore , The respiratory and digestive systems work together

to make usable ATP energy for cells. Is the correct option.

Answer:

C) NaCl

Explanation:

A hard substance that has a high melting point and is a poor conductor of electricity in the solid phase could be NaCl

This because it is an ionic compound.

Compounds like NaCl, MgO, NaF are in this category.

The hard substance that has a high melting point and is a poor conductor of electricity in the solid phase could be NaCl.

Electrolytes are substances which conduct electricity when in the molten or solution state.

Ionic compounds are compounds which are composed of oppositely charged ions held together by strong electrostatic forces. Ionic compounds all are electrolytes .

Therefore, the hard substance that has a high melting point and is a poor conductor of electricity in the solid phase could be NaCl.

Chemistry - Solutions

Explanation:

Step 1: Define

1 M C₆H₁₂O₆

1 L of solution

Step 2: Identify Conversions

Molar Mass of C - 12.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar mass of C₆H₁₂O₆ - 6(12.01) + 12(1.01) + 6(16.00) = 180.18 g/mol

Answer:

4 moles CO₂ = 4 moles O₂

Explanation:

The incorrect mole ratio is 4 moles CO₂ = 4 moles O₂.

 Let us write the reaction equation:

          2C₂H₅OH + 7O₂ → 4CO₂ +  6H₂O

To write mole ratios in a chemical reaction, we must ensure the equation is balanced.

Since the given expression is balanced,

   Then 4 moles CO₂ = 4 moles O₂ is not correct;

 Rather;

            4 moles CO₂ = 7 moles O₂ is the right expression

Answer:

a) Covalent

b)Polar Covalent

c)Ionic

d)Coordinate Covalent

Explanation:

The SiSi bond in Cl3SiSiCl3 is covalent, the SiCl bond in Cl3SiSiCl3 is polar covalent, the CaF bond in CaF2 is ionic and the NH bond in NH3 is covalent.

The covalent bond is defined as a chemical bond that involves sharing of an electron pair between the atoms.

A covalent bond formed when there difference is the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

The ionic bond is defined as a form of a chemical connection in which one atoms loses valance electrons and gain them from another.

A ionic bond is formed by interaction  of oppositely charge ions .

Thus, SiSi bond in Cl3SiSiCl3 is covalent, the SiCl bond in Cl3SiSiCl3 is polar covalent, the CaF bond in CaF2 is ionic and the NH bond in NH3 is covalent.

Fe2(SO4)3 has the greater iron content.

Explanation:

Hello!

In this case, considering the content of a specific element in a compound, we must take into account the subscript is has in the formula, for instance FeS has one iron atom, Fe2(SO4)3 has two iron atoms and FeCl2 has one iron atom; thus, by assuming one mole of each compound, we can compute the moles of iron there:

[tex]n_{Fe}^{FeS}=1molFeS*\frac{1molFe}{1molFeS}=1molFe \\\\n_{Fe}^{Fe_2(SO_4)_3}=1molFe_2(SO_4)_3*\frac{2molFe}{1molFe_2(SO_4)_3}=2molFe\\\\n_{Fe}^{FeCl_2}=1molFeCl_2*\frac{1molFe}{1molFeCl_2}=1molFe[/tex]

It means that  Fe2(SO4)3 would have the greatest iron content.

Answer:

only IV and V

Explanation:

If we look at the values of reduction potential for the two species, we will discover that vanadium has a negative reduction potential indicating its tendency towards oxidation.

On the other hand, solve has a positive reduction potential indicating a tendency towards reduction.

This implies that vanadium must be oxidized and silver reduced and not the not her way ground? Hence the answer above.

10 moles of water are required.

B)

Given data:

Moles of C₂H₄ used = ?

Moles of C₂H₅OH formed = 27 mol

Solution:

Chemical equation:

C₂H₄ + H₂O     →       C₂H₅OH

Now we will compare the moles of C₂H₄  with C₂H₅OH from balance chemical equation:

                    C₂H₅OH         :           C₂H₄  

                         1                 :             1

                         27               :            27
