One of the main components of an airbag is the gas that fills it. As part of the design process, you need to determine the exact amount of nitrogen that should be produced. Calculate the number of moles of nitrogen required to fill the airbag. Show your work. Assume that the nitrogen produced by the chemical reaction is at a temperature of 495°C and that nitrogen gas behaves like an ideal gas. Use this fact sheet to review the ideal gas law.

Answer:

540,000 (5.4X10^5)

Explanation:

kj means Kilojoules, while we are converting to joules.

- Kilo, or k, represents our base value, Joules, multiplied by 10^3. To convert to joules, we would simply multiply by 10^3 (which is 1000)

Answer:Answer B: About 0.20 grams of copper (II) is formed, and some aluminum is left in the reaction mixture

Explanation:

Answer:

3 Both mass and charge are conserved.

Explanation:

The equation of the reaction is;

Cu(s) + 2Ag+ (aq) → Cu2+ (aq)  + 2Ag(s)

A redox reaction is an acronym for oxidation-reduction reaction. This refers to a reaction in which the oxidation number of one specie is increased while the oxidation number of the other specie is decreased.

This means that one specie looses electrons while the other specie gains electrons. Here, Cu(s) looses electrons while Ag+(aq) gains electrons from left to right in the reaction.

In a redox reaction, both mass and charge are conserved. This means that the total mass and charge on the reactants side is the same as the total mass and charge on the products side.

The answers to your questions are given below.

Explanation:

1. __H₂ + __O₂ —> __H₂O

The above equation can be balance as follow:

H₂ + O₂ —> H₂O

There are 2 atoms of O on the left side and 1 atom on the right side. It can be balance by writing 2 before H₂O as shown below:

H₂ + O₂ —> 2H₂O

There are 2 atoms of H on the left side and a total of 4 atoms on the right side. It can be balance by writing 2 before H₂ as shown below:

2H₂ + O₂ —> 2H₂O

Now the equation is balanced.

Elements >>> Reactants >>> Products

H >>>>>>>>> 4 >>>>>>>>>>> 4

O >>>>>>>>> 2 >>>>>>>>>>> 2

2. __ P₄ + __O₂ —> __P₂O₃

The above equation can be balance as follow:

P₄ + O₂ —> P₂O₃

There are 4 atoms of P on the left side and 2 atoms on the right side. It can be balance by writing 2 before P₂O₃ as shown below:

P₄ + O₂ —> 2P₂O₃

There are 2 atoms of O on the left side and a total of 6 atoms on the right side. It can be balance by writing 3 before O₂ as shown below:

P₄ + 3O₂ —> 2P₂O₃

Now, the equation is balanced

Elements >>> Reactants >>> Products

P >>>>>>>>> 4 >>>>>>>>>>> 4

O >>>>>>>>> 6 >>>>>>>>>>> 6

Mass remains = (1/2)^n × (original mass)

Answer:

1577 °C

Explanation:

Step 1: Calculate the volume of the cylinder

The diameter of the base (d) is 13.0 cm and the height (h) is 15.6 cm. We will use the following expression.

V = h × π × (d/2)²

V = 15.6 cm × π × (13.0 cm/2)² = 8.28 × 10³ cm³ = 8.28 × 10³ mL = 8.28 L

Step 2: Calculate the moles of BF₃

We have 0.0985 kg (98.5 g) of BF₃, whose molar mass is 67.81 g/mol.

98.5 g × 1 mol/67.81 g = 1.45 mol

Step 3: Convert 2.70 MPa to atm

We will use the conversion factor 1 MPa = 9.86923 atm.

2.70 MPa × 9.86923 atm/1 MPa = 26.6 atm

Step 4: Calculate the maximum safe operating temperature

We will use the ideal gas equation.

P × V = n × R × T

T = P × V / n × R

T = 26.6 atm × 8.28 L / 1.45 mol × (0.0821 atm.L/mol.K) = 1850 K

We can convert 1850 K to Celsius using the following expression.

°C = K - 273.15 = 1850 K - 273.15 = 1577 °C

Explanation:

To show - from E=mc²=hv show that wavelength=h/mv​

Proof -

Given that,

E = mc²

E = hν

By equating both the equations, we get

mc² = hν

Because real particles do not travel at the speed of light, De Broglie submitted velocity ( v ) for the speed of light ( c ).

mv² = hν

Through the equation  λ , de Broglie substituted  v/λ  for  ν  and arrived at the final expression that relates wavelength and particle with speed.

mv² = hv/λ

⇒λ = hv/mv²

⇒λ = h/mv

Hence showed.

Answer: Activation energy

Explanation:

In a chemical reaction, the reactants contains particles which must collide in order for a reaction to occur. The rate of reaction depends on the frequency of effective collision between the reacting particles. Effective collision are those that result in reactions, which when they occur the colliding particles become activated with increased kinetic energy.

This energy must exceed a particular energy barrier for a particular reaction if the reaction must take place. This energy barrier that must be overcome before a reaction takes place is known as the ACTIVATION ENERGY.

To explain further, when two particles or molecules A and B come in contact with each other, for a reaction to take place, they must collide with a sufficient force to break the bond that exists between them. The minimum combined kinetic energy these reactant particles must possess in order for their collision to result in a reaction is called the activation energy.

Hello there!

In this case, according to the given information, it turns out possible for us to realize this is a question about esterification, process whereby a carboxylic acid and an alcohol react to produce water an an ester, we can set it up as shown below:

[tex]CH_3COOH+CH_3CH_2CH_2CH_2OH[/tex]

For the reaction between ethanoic acid and butanol; and therefore, the products side is:

[tex]CH_3COOCH_2CH_2CH_2CH_3+H_2O[/tex]

It means that the overall equation is:

[tex]CH_3COOH+CH_3CH_2CH_2CH_2OH\rightarrow CH_3COOCH_2CH_2CH_2CH_3+H_2O[/tex]

And the ester product is butyl ethanoate.

Answer:

By measuring out 3.9 grams of cobalt (II) chloride up to a volume of 1.0 L of solution.

Explanation:

Hello there!

In this case, considering this question about molarity, it turns out possible for us to calculate the required mass of cobalt (II) chloride by firstly compute the moles present in 1.0L of the given 0.03-M solution:

[tex]M=\frac{n}{V} \\n=V*M\\\\n=1.0L*0.03\frac{molCoCl_2}{L}\\\\n=0.03molCoCl_2[/tex]

Next, since the molar mass of cobalt (II) chloride is 129.84 g/mol, we compute the grams we need to measure out in order to prepare this solution:

[tex]m_{CoCl_2}=0.03molCoCl_2*\frac{129.84gCoCl_2}{1molCoCl_2} \\\\m_{CoCl_2}=3.9gCoCl_2[/tex]

Answer:

The data will be error free and more correct.

Explanation:

The data will show no error while testing the adsorptive properties of a new material if no centrifuge method is not used because there is no need for centrifuge method. For determining the adsorptive properties of a new material, we can measure the data after dissolving . Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface while on the other hand, Centrifugation is the process where a mixture is separated from one another through fast spinning. so for determining the adsorptive properties, no centrifugation process is required and we get the correct data without centrifugation.

Answer:

well when you eat some food you will get many tastes mixed with base and acid but salt from NA2CO3 can be a base if it is contained with weak acid.

Explanation:

Basically SALT can be one common base that is NOT harmful to the body when ingested AND a product, or way, in which it is used.

Magnesium hydroxide (Mg(OH)2) is not harmful to our body when ingested AND a product, or way, in which it is used. It is commonly used to get relief from acidity, that is caused when our stomach releases excessive acid. It neutrelises the acid and gives us relief. It is also called Milk of Magnesia commonly.
