How many moles of I2 are in 8.23 moles of NaI ?

Answers

Answer: 4.12

Explanation:

we know that the given mol is 8.23 mol and they are 2NaI and I2 so we will write the equation like this.

8.23mol NaI x 1mol of I2 ÷ 2molNaI = 4.115≅ 4.12 mol of I2

we placed NaI at the bottom to cancel out with the 8.23 mol of NaI

I have a chemistry writing promp but it’s asking questions here the prompt: What is the empirical formula if you have 36.84% nitrogen and 63.16% oxygen? State three potential molecular formulas from the empirical formula in A. If the molecular formula mass in A is 760 grams/mol, what is the molecular formula? WIll the molecular and empirical formulas in A and D have the same characteristics? Why or why not?

Answers

Explanation:

1. Find the empirical formula of a compound that has 36.84% of Nitrogen (N), 63.16% of Oxygen (O).

Secondly, Find molar mass of each component: N=14.0067, O=15.9994

Thirdly, convert to moles: N=2.6301698472874, O=3.9476480368014

Then find smallest mole value: 2.6301698472874

Divide all components my smallest value: N=1, O=1.5009099282591

Then divide by fractional component of each mole value: N=1.9963668986866, O=2.9963668986866

Round to closest whole numbers: N=2, O=3

Lastly, combine to get the empirical formula:N2O3

a 2.7 L of N2 is collected at 121kpa and 288 K . if the pressure increases to 202 kpa and the temperature rises to 303 K , what volume will the gas occupy?

Answers

Answer:

The gas will occupy a volume of 1.702 liters.

Explanation:

Let suppose that the gas behaves ideally. The equation of state for ideal gas is:

[tex]P\cdot V = n\cdot R_{u}\cdot T[/tex] (1)

Where:

[tex]P[/tex] - Pressure, measured in kilopascals.

[tex]V[/tex] - Volume, measured in liters.

[tex]n[/tex] - Molar quantity, measured in moles.

[tex]T[/tex] - Temperature, measured in Kelvin.

[tex]R_{u}[/tex] - Ideal gas constant, measured in kilopascal-liters per mole-Kelvin.

We can simplify the equation by constructing the following relationship:

[tex]\frac{P_{1}\cdot V_{1}}{T_{1}} = \frac{P_{2}\cdot V_{2}}{T_{2}}[/tex] (2)

Where:

[tex]P_{1}[/tex], [tex]P_{2}[/tex] - Initial and final pressure, measured in kilopascals.

[tex]V_{1}[/tex], [tex]V_{2}[/tex] - Initial and final volume, measured in liters.

[tex]T_{1}[/tex], [tex]T_{2}[/tex] - Initial and final temperature, measured in Kelvin.

If we know that [tex]P_{1} = 121\,kPa[/tex], [tex]P_{2} = 202\,kPa[/tex], [tex]V_{1} = 2.7\,L[/tex], [tex]T_{1} = 288\,K[/tex] and [tex]T_{2} = 303\,K[/tex], the final volume of the gas is:

[tex]V_{2} = \left(\frac{T_{2}}{T_{1}} \right)\cdot \left(\frac{P_{1}}{P_{2}} \right)\cdot V_{1}[/tex]

[tex]V_{2} = 1.702\,L[/tex]

The gas will occupy a volume of 1.702 liters.

What is the mole of ammonia produced from 7.23 x 10−4 moles of the hydrogen reactant, assuming there is sufficient nitrogen to react?


7.23 x 10−47.23 x 10−4

8.42 x 10−38.42 x 10−3

4.82 x 10−44.82 x 10−4

4.83 x 10−3

Answers

Answer:

4.82 x 10^-4

Explanation:

7.23 x 10^-4 mol H2   l    2 mol NH3

------------------------------------------------------- =  

                                   l    3 mol H2

(7.23 x 10^-4) x 2   /  3 =

4.82 x 10^-4

Hope this helped! ;)

The mole of ammonia produced from 7.23 x 10⁻⁴ moles of the hydrogen reactant when there is sufficient nitrogen to react is 4.82×10⁻⁴.

What is moles?

Moles is a unit which is used to estimate the amount of any substance and it is represented as:
n = W/M , where

W = given mass

M = molar mass

Given chemical reaction is:
N₂(g) + 3H₂(g) → 2NH₃(g)

In the question it is given that sufficient moles of N₂ is present, so the formation of product depends on the moles of H₂. From the stoichiometry of the reaction, it is clear that:

3 moles of H₂ = produce 2 moles of NH₃

7.23×10⁻⁴ moles of H₂ = produce 2/3 × 7.23×10⁻⁴=4.82×10⁻⁴ moles of NH₃

Hence, option (C) is correct i.e. 4.82×10⁻⁴.

Explanation:

Answer:

The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area's elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and thunderstorms resulting from air-mass differences; and the distribution of air pressure over the land and nearest oceans, which produces varying wind and air mass patterns.

what happens when bromine water is added to ethane and ethene​

Answers

Answer:

Bromine water reacts with ethane as it is able to break open the double bond, forming 1,2-dibromoethane. This double bond is not present in ethane, so bromine water does not react with it. This reaction is known as electrophilic addition.

Explanation:

Ethene will readily react with bromine, so the colour of the bromine water changes from red-brown to colourless. Bromine atoms will add across the double bond in ethene to produce just one product; 1,2-dibromoethane.

A) The puck does not lose any speed because ice is a very slippery surface.

B) The puck gradually slows down because mass makes objects slow down.

C) The puck gradually slows down because friction would be acting on it.

D) The puck does not lose any speed because once an object starts moving, the force of friction would no longer apply to it.

Answers

Answer:

C) The puck gradually slows down because friction would be acting on it.

A 1500 N force gives an object an acceleration of 3 m/s2.

What is the mass of the object?

Answers

Answer:

500kg.

Explanation:

Newton's Second Law relates force, mass and acceleration to one another through the equation:

F = ma

We can rearrange this equation algebraically to solve for mass:

m = F/a

Substituting our known values for the variables, we get:

m = 1500N/3m/s2

So mass of the object is 500kg.

We know it's kg because Newtons (N) are a unit defined as 1 kg/m/s2, so m/s2 cancels out when we divide :)

A small cart with a mass of 3.0 kg is accelerated from rest and obtains a final velocity of 24 m/s, East in 8.0 s. If friction is neglected, what net force is applied.

A sample of oxide iron weighing 2.40g was heated in a stream of hydrogen until it was completely converted to the metal. If the metal weighed 1.68g. What is the formula of the iron oxide? (Fe=56, O=16)

Answers

Answer:

Fe₂O₃

Explanation:

To solve this question we must find the moles of Iron in 1.68g. With the difference of the masses we can find the moles of oxygen. The formula will be obtained with the ratio of both amount of moles:

Moles Fe:

1.68g * (1mol / 56g)  =0.03moles

Moles O:

2.40g-1.68g = 0.72g * (1mol/16g) = 0.045moles

The ratio O/Fe is:

0.045moles / 0.03moles = 1.5 moles. this ratio is obtained if the formula is:

Fe₂O₃

c. The thick layer of air surrounding the earth

d. Carbon dioxide does not support this process​

Answer:

a. Pollutant.

b. Oxygen.

c. Atmosphere.

d. Combustion.

Explanation:

a. Pollutant: an undesirable constituent of air. Pollution can be defined as the physical degradation or contamination of the environment through an emission of harmful, poisonous and toxic chemical substances known as pollutants. Some examples of pollutant are carbon monoxide, nitrogen dioxide, ozone, etc.

b. Oxygen: the constituent of air that helps in burning. Oxygen is an element that aids in the combustion (burning) process because it is an oxidizing agent.

c. Atmosphere: the thick layer of air surrounding the earth. It comprises of nitrogen, oxygen, carbon dioxide, argon and other gases in very small proportion.

d. Combustion (burning): Carbon dioxide does not support this process but it is an end product of the process.

Combustion can be defined as an exothermic chemical reaction between physical substances, usually in the presence of oxygen and hydrocarbons to produce heat, light and carbon.

2Fe3+ (aq) + 6Cl- (aq) + 3Mg(s) ® 3Mg2+ (aq) + 6Cl- (aq) + 2Fe(s)

Answers

Answer: [tex]2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)[/tex]

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and are present in an aqueous state and represented in the form of ions.

Net ionic equation : In the net ionic equations, we do not not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

 The complete balanced ionic equation will be:

[tex]2Fe^{3+}(aq)+6Cl^-(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+6Cl^-(aq)+2Fe(s)[/tex]

 In this equation, [tex]Cl^-[/tex] are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be:

[tex]2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)[/tex]
