What is a net ionic equation?

A chemical equation which shows only those elements, compounds, and ions which are directly involved in the chemical reaction is defined as the net ionic equation. The net ionic equation give us information about the ions that exists in aqueous medium.

A net ionic equation does not consider the spectator ions. The ions which do not participate in chemical reactions and are seen on both sides of the reactions are called spectator ions.

The complete ionic equation for the given reaction is:

3Na⁺ (aq) + PO₄³⁻ (aq) + Fe³⁺ (aq) + 3Cl⁻ (aq) → 3Na⁺ (aq) + 3Cl⁻ (aq) + FePO₄ (s)

The net ionic equation is:

Answers

Answer:

Cu⁺² is being reduced in that reaction.

Explanation:

Zn(s) + Cu⁺²(aq) → Zn⁺²(aq) + Cu(s)

When a substance is reduced, its oxidation number is reduced -changing to a lower value than original-.

Cu⁺² turned into Cu. Meaning that the oxidation number changed from +2 to 0.

Thus, Cu⁺² is being reduced in that reaction.

What are the reactants in this equation?

Answers

I think it may be A but I’m not to certain

Answer:

[tex]\boxed {\boxed {\sf A. \ NaI \ and \ Pb(NO_3)_2}}[/tex]

Explanation:

In a chemical reaction, the reactants are the substances that start the reaction and change into other substances. The results at the end of the reaction are products.

Typically, the reactants are to the left of the arrow, while products are to the right.

reactants ⇒ products

We are given this chemical equation:

[tex]2 \ NaI + Pb(NO_3)_2 \rightarrow 2NaNO_3 +PbI_2[/tex]

We are asked to find the reactants. Remember, these go into the reaction and are on the left.

[tex]\bold {2 \ NaI + Pb(NO_3)_2 } \rightarrow 2NaNO_3 +PbI_2[/tex]

Therefore, the reactants are NaI (sodium iodide) and Pb(NO₃)₂ (lead nitrate). Choice A is correct.

2 KO₂ + H₂O = 2 KOH + 1.5 O₂

Explanation:

Let's consider the following unbalanced equation.

C₆H₁₂O₆ + O₂ = CO₂ + H₂O

We will start balancing H atoms (higher atomicity) by multiplying H₂O by 6.

C₆H₁₂O₆ + O₂ = CO₂ + 6 H₂O

Then, we will balance C atoms by multiplying CO₂ by 6.

C₆H₁₂O₆ + O₂ = 6 CO₂ + 6 H₂O

Finally, to get the balanced equation, we will multiply O₂ by 6.

C₆H₁₂O₆ + 6 O₂ = 6 CO₂ + 6 H₂O

---

Let's consider the following unbalanced equation.

KO₂ + H₂O = KOH + O₂

We will multiply KO₂ and KOH by 2 to balance K and H atoms.

2 KO₂ + H₂O = 2 KOH + O₂

Finally, to get the balanced equation, we will multiply O₂ by 1.5.

2 KO₂ + H₂O = 2 KOH + 1.5 O₂

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

The longest continuous carbon chain comprises five carbon atoms connected by single bonds, so the root name will be pentane.

Thus, the name of this molecule would be 3-methylpentane.

when 70.0 grams of mno2 reacted with 128.0 grams of hcl, the reaction resulted in a 62.7% yield of chlorine gas. what is the actual yield of chlorine gas in grams? Mno2 + HCI —> MnCl2 + h2o + cl2​

Answers

Answer:

35.8g of Cl₂ is the yield

Explanation:

Based on the reaction:

MnO₂ + 4HCl → MnCl₂ + 2H₂O + Cl₂

1 mole of MnO₂ and 4 moles of HCl react producing 1 mole of Cl₂

To solve this question we must find limiting reactant. with limiting reactant we can find the theoretical yield of Cl₂. As the actual yield is the 62.7% we can find actual yield of Cl₂ in grams:

Moles MnO₂ -Molar mass: 86.9368g/mol-:

70.0g * (1mol / 86.9368g) = 0.805 moles

Moles HCl -Molar mass: 36.46g/mol-:

128.0g * (1mol / 36.46g) = 3.51 moles

For a complete reaction of 3.51 moles of HCl are required:

3.51 moles HCl * (1mol MnO₂ / 4mol HCl) = 0.878 moles MnO₂.

As there are just 0.805 moles of MnO₂, MnO₂ is limiting reactant.

1 mole of MnO₂ produce 1 mole of Cl₂. The theoretical moles of Cl₂ produced are 0.805 moles.

As the yield is of 62.7%, the yield of Cl₂ is:

0.805 moles * (62.7 / 100) = 0.505 moles Cl₂. In grams:

0.505 moles Cl₂ * (70.906g / mol) =

35.8g of Cl₂ is the yield

How do you balance this:
Br2 + H2O + SO2 = HBr + H2SO4

Answers

Answer:

Br2+ 2H2O + SO2= 2HBr + H2SO4

Let's Compare the left side of the equation to the right side of the equation.

Left: Br= 2, H= 2, S= 1, O = 1+2

Right: Br=1, H= 1+2, S=1, O= 4

We can see that only S is balanced and not the other 3 elements.

I'll try to make each element balance.

For Br; I'll multiply by 2 on the left to make it equal to the right.

For H; Since the 2 for Br on the right affected also H, that H ( for HBr) Already has a 2, but then it adds with the other H2( for H2SO4) to give a total of 4 H on the right side. But then there's only 2 H on the left. so we multiply that 2 by a 2 ( which is written infront of the H2O to give a total of 4 H on the left side.

For O; Because of the 2 infront of the H2O, it affects the O in H2O..so now we have 2 O plus the 2 O ( in SO2) to give a total of 4 O which is equal to the right side.

3. What is the mass % of a solution that contains 36g KCl in 475g of water?

Answers

Answer:

%KCl = 7.05%

%Water = 92.95%

Explanation:

Step 1: Given data

Mass of KCl (solute): 36 gMass of water (solvent): 475 g

Step 2: Calculate the mass of the solution

The mass of the solution is equal to the sum of the masses of the solute and the solvent.

m = 36 g + 475 g = 511 g

Step 3: Calculate the mass percentage of the solution

We will use the following expression.

%Component = mComponent/mSolution × 100%

%KCl = 36 g/511 g × 100% = 7.05%

%Water = 475 g/511 g × 100% = 92.95%

N2 + H2 --> NH3 (unbalanced) How many moles of NH3 are produced when 6.3 moles of H2 gas react with N2 gas?

Answers

Answer:

4.2 mol NH3

Explanation:

First, balance your reaction.

N2 + 3H2 --> 2NH3

Multiply 6.3 mol H2 by the mole ratio of 2 mol NH3 for every 3 mol H2 to get moles of NH3 produced.

6.3 mol H2 • (2 mol NH3 / 3 mol H2) = 4.2 mol NH3

Which statement is TRUE according to the kinetic molecular theory? Which statement is TRUE according to the kinetic molecular theory? A single particle does not move in a straight line. The average kinetic energy of a particle is proportional to the temperature in Kelvin. The size of the particle is large compared to the volume. The collisions of particles with one another is not completely elastic.

Answers

Answer:

The average kinetic energy of a particle is proportional to the temperature in Kelvin.

Explanation:

The kinetic molecular theory states that particles of matter are in constant motion and collide frequently with each other as well as with the walls of the container.

The collisions between particles are completely elastic. The kinetic energy of the particles of a body depends on the temperature of the body since temperature is defined as a measure of the average kinetic energy of the particles of a body.

Therefore, the average kinetic energy of a particle is proportional to the temperature in Kelvin.

Four postulates make up the kinetic-molecular theory of gases: A gas is made up of molecules moving randomly all the time. Gas molecules exclusively interact with one another through collisions; they do not apply any other forces. Every gas molecule collision is fully elastic, and all kinetic energy is conserved. Here the correct option is B.

According to the kinetic molecular theory, collisions between gas particles occur in perfect elastic motion and are always in motion. Boyle's and Charles's laws can both be explained by the kinetic molecular theory. Only absolute temperature directly affects a group of gas particles' average kinetic energy.

The collisions between particles are completely elastic. The kinetic energy of the particles of a body depends on the temperature of the body since temperature is defined as a measure of the average kinetic energy of the particles of a body.

Thus the correct option is B.

9.16 liters of CO2 weighs how many grams?

Your answer

Answers

Answer:

18.0g of CO₂ are present in 9.16L

Explanation:

To solve this question we must use:

PV = nRT

In order to find the moles of the gas and with its molar mass (44.01g/mol for CO₂) we can find the mass of the gas

Assuming STP conditions:

P = 1atm at STP

V = 9.16L

n are the moles of CO₂

R = 0.082atmL/molK

T = 273.15K

Replacing:

PV / RT = n

1atm*9.16L / 0.082atmL/molK*273.15K = n

0.409 moles = Moles of CO₂

The mass is:

0.409 moles CO₂ * (44.01g / mol) =
