Consider the total ionic equation below.

Ba2+ + 2NO3 + 2Na+ + Co3 —BaCO3 + 2Na+ + 2NO3

Which is the net ionic equation for the reaction?

O Ba2+ + C03 —> BaCO3

© 2Na+ + co} → Na2CO3

NO3 + Na* —> NaNO3

O Ba2+ + 2NO3 →→ Ba(NO3)2

Answers

Answer 1

Answer:

Ba²⁺ + CO₃²⁻ → BaCO₃

Explanation:

A net ionic equation is a way to write a chemical reaction in which you list only the species that are participating in the reaction.

For the reaction:

Ba²⁺ + 2NO₃ + 2Na⁺ + CO₃²⁻ → BaCO₃ + 2Na⁺ + 2NO₃

As you can see, NO₃ and Na⁺ are not participating in the reaction. Thus, net ionic equaation is:

Ba²⁺ + CO₃²⁻ → BaCO₃

Answer 2

Complete Question

Consider the total ionic equation below.

[tex]Ba^{2+} + 2NaO_3^{1 -} + 2Na^{+} + CO_3^{2-} ----> BaCO_3 + 2Na^{+} + 2NO_3^{1-}[/tex]

Which is the net ionic equation for the reaction?

A [tex]Ba^{2+} _{(aq)} + CO_3 ^{2-} _{(aq)} ----> BaCO_3_{(s)}[/tex]

B [tex]2Na^+ + CO_2 ----> Na2CO3[/tex]

C [tex]NO3 + Na ^ + ----> NaNO3[/tex]

D   [tex]Ba_2^+ + 2NO3 ----> Ba(NO3)2[/tex]

Answer:

Option A is the correct option

Explanation:

The given ionic equation is

       [tex]Ba^{2+} + 2NaO_3^{1 -} + 2Na^{+} + CO_3^{2-} ----> BaCO_3 + 2Na^{+} + 2NO_3^{1-}[/tex]

Looking at this complete ionic equation we see that [tex]Na^{+1} \ and \ NO_3^{1-}[/tex] did not change in the reaction so they will not be included in the net ionic equation so the net ionic equation becomes

         [tex]Ba^{2+} _{(aq)} + CO_3 ^{2-} _{(aq)} ----> BaCO_3_{(s)}[/tex]

Sulfuric acid (H2SO4) has a molar mass of 98.1 g/mol. How many oxygen atoms are found in 75.0 g of H2SO4? A. 1.15 × 10^23 B. 1.84 × 10^24 C. 4.61 × 10^23 D. 7.87 × 10^23

Answers

Answer:

B

Explanation:

first find the no. Of moles of H2SO4

=  75/98.1

= 0.7645

Next step

In on mole of H2SO4 the no.of oxygen atom is 4.

1 H2SO4 : 4 O

0.7645  : x                     x= 0.7645x4= 3.0581

next multiply avogadros constant

3.0581 x 6.022× 10^23 =1.84x10^24

Mass present in 1 gram of mole substance is called molar mass. Molar mass is calculated by: dividing the mass of the compound in grams by the number of moles present in the substances.

The correct answer is:

option B. 1.84 × 10²⁴

Given,

The mass of sulfuric acid =75.0 g

The molar mass of sulfuric acid = 98.1 g/mol

1.The moles of sulfuric acid can be calculated by

M = m ÷ n

where M is molar mass, m is mass and n moles.

moles of sulfuric acid = mass ÷ molar mass

= 75 g ÷ 98.1 g/mol  

=0.7645 moles

Hence moles of sulfuric acid present is 0.7645 moles.

2. 1 mole of sulfuric acid = 4 oxygen atoms.

Then, 0.7645 moles of sulfuric will contain: 0.7645 × 4 = 3.0581 atoms of oxygen

3. Oxygen atoms present in 75.0 g of H₂SO₄ will be calculated by multiplying it with Avogadro's constant:

= 3.0581 x 6.022× 10²³

= 1.84x10²⁴

Therefore, 1.84 × 10²⁴ oxygen atoms will be found in 75.0 g of H₂SO₄.

Discribe how an internal combustion engine works. What is drawback to the type of power?

Answers

Answer:

An internal combustion engine is a heat engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber. The force of combustion is converted into mechanical energy through the use of levers and gears. The by products of combustion include energy, water vapor, carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2), and carbon monoxide (CO). The two primary drawbacks to the internal combustion engine are the primary energy source is non-renewable (fossil fuels) and the by products can have damaging effects on the environment.

10) Intravenous saline solutions have a concentration of 1.5 M NaCl. How many liters of saline can be prepared from 50.0 g of NaCl?

Answers

Answer:

0.57 mol/L

Explanation:

Molarity (M) is defined as the number of moles of solute per liter of solution (moles/Liter).

Molarity  =  [tex]\frac{moles of solute}{liters of solution}[/tex] or Moles  =  molarity × litres

so, the mass of Nacl in 1 mol is 58.44 g,

Moles of NaCl = 50.0g x 1 mole NaCl / 58.44 g

                          = 0.855 mol NaCl

Moles  =  molarity × litres

0.855 = 1.5 M x L

L = 0.57 mol/L

Hence, 0.57 mol/L can be prepared from 50.0 g of NaCl.

Cylinder A contains a gas whose molecules have an average speed of 0.0000001 meters/sec. Cylinder B contains a gas whose molecules have an average speed of 0.3 meters/sec. Select the statement below that is true regarding these cylinders. options: Cylinder A contains a gas that has a temperature closest to absolute zero. Even though the molecules are moving at different speeds in the two cylinders, they have the same kinetic energy. Cylinder B contains molecules that are moving more slowly than the molecules in Cylinder A. Cylinder B contains a gas that has a temperature closest to absolute zero.

Answers

Answer:

The correct option is;

Cylinder A contains a gas that has a temperature closest to absolute zero

Explanation:

From the kinetic theory of gases, the average speed of a gaseous molecule is found from the following equation;

[tex]v_{rms} = \sqrt{\frac{3\cdot R \cdot T}{MW} }[/tex]

Where:

[tex]v_{rms}[/tex] = rms speed which is the square root of the average of the velocities of the gas molecules squared which is used in place of the average of the gas molecules as the sum of the velocities of all the gas molecules in the cylinder is zero

R = Universal gas constant = 8.3145 J/(mol·K)

MW = Molecular weight of the gas

Hence where we have;

[tex]v_{rmsA}[/tex] = Average velocity of gas A = 0.0000001 m/s

[tex]v_{rmsB}[/tex] = Average velocity of gas B = 0.3 m/s

Since, R and MW are constant for the gas in cylinder A constant, therefore, as [tex]v_{rmsA}[/tex] ≈ 0 m/s, the temperature, [tex]T_A[/tex], of gas A is closest to absolute zero.

The particle represented by X(aq) is


A) H2PO4–(aq)

B) HPO42–(aq)

C) PO43–(aq)

D) H3PO4(aq)

Answers

Answer:

The particle represented by X(aq) is  A) H₂PO₄⁻(aq)

Explanation:

According to the Brønsted-Lowry Theory, a base is a substance capable of accepting protons (H⁺) in solution. Conversely, a substance acts as an acid if it acts as a proton donor.

A proton transfer then occurs, requiring the presence of a proton donor (an acid) and a base that accepts them.

When an acid gives up a proton, it becomes an anion, generating a conjugate base. That is, a conjugate base is an ion or molecule resulting from the acid that loses the proton. Conversely, a conjugated acid is an ion or molecule resulting from the base that the proton gains.

In this NH₃ / NH₄⁺ pair that NH₄⁺ is the conjugate acid of the NH₃ base, the latter acting as a base since it accepts a proton. H₃PO₄ then acts as an acid, yielding a proton and generating the conjugate base H₂PO₄⁻.

So, the particle represented by X(aq) is  A) H₂PO₄⁻(aq)

An example of a double replacement chemical reaction takes place in batteries. In an alkaline battery, Manganese oxide reacts with water to form a different manganese oxide and hydroxide. Which is the correct balanced equation for this?

Answers

Answer:

2MnO2 + H2O => Mn2O3 + 2OH is the correct balanced equation.

When manganese oxide reacts with water to form a different manganese oxide and hydroxide, the correct balanced equation for this is 2MnO₂ + H₂O ⇾ Mn₂O₃ + 2OH.

What do you mean by balanced chemical equation ?

The term balance chemical equation is define as the equation which satisfy the law of conservation of mass, i.e., “Total mass of the products is equal to the total mass of all the reactants”.

If a chemical equation is not balanced, it will break the law of conservation of mass. It will indicate that either mass is created or destroyed, which is impossible.

Balanced chemical equations have the equal number and type of each atom on both sides of the equation.  

Thus, When manganese oxide reacts with water to produce a different manganese oxide and hydroxide, the correct balanced equation for this reaction is 2MnO₂ + H₂O ⇾ Mn₂O₃ + 2OH.

A chemistry student mixes 25 milliliters of 3.0 M hydrochloric acid (HCl) with excess sodium hydroxide. The chemicals react according to this chemical equation:

HCl + NaOH → NaCl + H2O.

If the volume of the resulting solution is 68 milliliters, what is the concentration of sodium chloride?

Answers

Answer:

1.1 mol/liter

Explanation:

You would use the M1V1 = M2V2 equation to solve this.

We know M1 is 3.0 M, V1 is 25 milliliters, and V2 is 68 milliliters. We need to find M2.

To find M2, first plug in what you know.

(3.0 M)(25 mL) = M2(68 mL)

Then, divide everything by 68 mL to get M2 by itself

Your answer should be a quite large decimal but I rounded it to 1.1 mol/liter.
