a gas container with a volume of 271 mL contains 0.26 moles of gas. Gas is added to the container so that it now contains 0.80 mole of gas. what is the new volume in milliliters

Answers

Answer 1

Answer:

V₂  = 833.85 mL

Explanation:

Given data:

Initial volume V₁= 271 mL

Initial number of moles n₁= 0.26 mol

Final number of moles n₂= 0.80 mol

Final/new volume V₂ = ?

Solution:

V₁/n₁   =    V₂/n₂

Now we will put the values in formula.

271 mL / 0.26 mol = V₂ / 0.80 mol

V₂  = 271 mL × 0.80 mol / 0.26 mol

V₂  = 216.8 mL.mol /  0.26 mol

V₂  = 833.85 mL

What type of bond will result if the atoms below combine? The electronegativity of each atom is given.
Cs0.79
F4.0

Answers

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.

An ionic bond usually forms between metals and non-metals. The metal being electropositive has a very low electronegativity value. Non-metals are electronegative. The Cs will lose it electrons to F This leaves a net negative charge on F and a net positive charge on Cs.

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.

A bottle with a mass of 6.8 g has 23.1 mL of a liquid placed in it. The combined mass of the bottle and the liquid is now 48.8 g. Find the density of the liquid. Give the correct number of significant figures in the answer according to the rule.

Answers

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

Choose the mole ratio below that is INCORRECT based on the given balanced equation:

2 C2H5OH + 7 O2 --> 4 CO2 + 6 H2O

O 2 moles C2H5OH = 4 moles CO2

O 7 moles O2 = 2 moles C2H5OH

O 4 moles CO2 = 4 moles O2

O 6 moles H2O = 7 moles O2

Answers

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

What's the molality of a solution with 120 g of NaCl and 30 kg of water?

Answers

Answer:

0.07mol/kg

Explanation:

Given parameters:

Mass of NaCl solution  = 120g

Mass of water  = 30kg

Unknown:

Molality of the solution =?

Solution:

The molality of a solution is the number of moles of the solute per mass of the solution.

 Molality  = [tex]\frac{number of moles of solute}{mass of solution}[/tex]  

  Number of moles of NaCl  = [tex]\frac{mass}{molar mass}[/tex]  

 Molar mass of NaCl  = 23 + 35.5  = 58.5g/mol

   Number of moles of NaCl  = [tex]\frac{120}{58.5}[/tex]   = 2.05mole

So;

  molality  = [tex]\frac{2.05}{30}[/tex]   = 0.07mol/kg

A hard substance that has a high melting point and is a poor conductor of electricity in the solid phase could be
A) CO2
B) Mg
C) NaCl
D) CCl4

Answers

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.

Ionic compounds are formed via the electrostatic attraction between oppositely charged ions. Ionic substances have high melting point as solids and as liquids, they have a high boiling point. In aqueous solutions or in molten form, ionic compounds can conduct an electric current using free mobile ions as carriers. In solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.

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

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

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.

The analysis of a compound containing K, P and O showed 55 % K, 15 % P and 30 % O, set up the simplest empirical formula of this compound.

Answers

Answer:

Empirical formula is K₃PO₄.

Explanation:

Given data:

Percentage of K = 55%

Percentage of P = 15%

Percentage of O = 30%

Number of gram atoms of O = 30 / 15.999 = 1.88

Atomic ratio:

             K                      :          P                   :         O

           1.41/0.48            :       0.48/0.48        :       1.88/0.48

               3                     :           1                    :            4

B. If you need to produce 27 mol C2H5OH how many moles of C2H4 will be used?

Answers

Answer:

A: 10 moles of water are required.

B: 27 moles of C₂H₄  are used.

Explanation:

A:

Given data:

Moles of water used = ?

Moles of C₂H₅OH formed = 10 mol

Solution:

Chemical equation:

C₂H₄ + H₂O     →       C₂H₅OH

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

                    C₂H₅OH            :           H₂O  

                         1                   :             1

                       10                  :         10

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

What is covalent bond?

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.
