Explanation:

Answer:

5250 Joules

Explanation:

Mass = 50g

Initial Temperature = 125.0 degrees Celsius

Final Temperature =  100 degrees Celsius

Temperature change = Final - Initial = 100 - 125 = -25

Heat = ?

These quantities are related by the equation;

H = mCΔT

where c = specific hear capacity = 4.2 J/g°C

H = 50 * 4.2 *  (-25)

H = -5250 J (The negative sign is because heat is being released)

Answer:carbon dioxide is released during combustion

Answer:

22

Explanation:

The atomic number indicates the amount of protons, so it would be 22

mass = mol no. x molar mass
         = 6.2 x 23
         = 142.6 g

Answer:

0.43 atm

Explanation:

From the question given above, the following data were obtained:

Initial pressure (P₁) = 0.95 atm

Initial volume (V₁) = 0.55 L

Final volume (V₂) = 1.22 L

Final pressure (P₂) =?

The final pressure of the gas can be obtained by using the Boyle's law equation as follow:

P₁V₁ = P₂V₂

0.95 × 0.55 = P₂ × 1.22

0.5225 = P₂ × 1.22

Divide both side by 1.22

P₂ = 0.5225 / 1.22

P₂ = 0.43 atm

Therefore, the final pressure of the gas is 0.43 atm

The final pressure of the gas is 0.43 atm.

Pressure is the process of force exerted perpendicular to any surface.

Given, the Initial pressure (P₁) is 0.95 atm

The initial volume (V₁) is 0.55 L

The final volume (V₂) is 1.22 L

To find the final pressure (P₂)

By the Boyle's Law

[tex]\rm P_1V_2= P_2V_2[/tex]

[tex]\rm 0.95\times 0.55 = P_2\times1.22\\\\0.5225 = P_2 \times 1.22\\\\Divided\;both \;side\;by\;1.22\\\\P_2=\dfrac{0.5225}{1.22} = 0.43 atm.[/tex]

Thus, the final pressure of the gas is 0.43 atm.

Answer:

The correct answer is - anhydrous aluminum chloride is covalent whereas anhydrous magnesium chloride is ionic.

Explanation:

Anhydrous aluminum chloride is a covalent compound and we know that covalent compounds have less or no polarity. Organic compounds or solvents are mostly non-polar in nature. And it is a thumb rule that like-dissolves-like.

Thus they dissolve covalent molecules like anhydrous aluminum chloride.

Anhydrous magnesium chloride is an ionic compound that tends to interact with a polar solvent but not in a non-polar solvent such as organic solvents.

Anhydrous aluminum chloride is fairly soluble in the organic solvent while anhydrous magnesium chloride is insoluble​ because anhydrous aluminum chloride is covalent whereas anhydrous magnesium chloride is ionic.

AlCl3 quite simply accepts electrons from other atoms, in an try and get a full valence shell of eight electrons. It's why it normally behaves as a Lewis acid. In the response under, the Al atom accepts a lone pair of electrons from a Cl atom.

AlCl3 is hygroscopic and has a great affinity for water. Therefore, aluminum chloride dissolves in water partially.

Explanation:

Answer:

The two spots will move up the plate.

Explanation:

We have to first understand the rudiments of chromatography. In chromatography, there is a stationary phase and a mobile phase. The stationary phase does not move. In this case, the stationary phase is the TLC plate.

The mobile phase is the solvent used to perform the chromatography. The movement of the spots depends on the composition of the solvent.

When neat hexane was used, only one spot was moved. This must be due to the interaction of the nonpolar hexane with the less polar compound. However, when a 50/50 mixture of hexanes and ethyl acetate is used, the both compounds are found to move up the plate.

Answer:

1860 torr

Explanation:

In order to convert from kPa to torr, we are going to use the following conversion factor:

Now we multiply 248 kPa with this factor so that the kPa units cancel each other and only the torr units remain:

This means that the answer is 1860 torr.

Answer:

Well no because if metals lose electrons, any non-metal sources/items gain electrons from the metal.

Answer:

Metals tend to lose electrons and non-metals tend to gain electrons, so in reactions involving these two groups, there is electron transfer from the metal to the non-metal

Answer:

3.5hrs

Explanation:

Using the formula Speed = Distance/Time

Given

Speed = 8mi/hr

Distance = 28miles

Get the time

Time = Distance/Speed

Time = 28/8

Tme = 3.5hrs

Hence it will take 3.5hrs to travel

Answer:

If we know that a reaction is an elementary reaction, then we know its rate law.

Explanation:

An elementary reaction is a reaction that takes place in one reactive encounter. This means that the two species interact in a single step to give the products.

If two reactants interact in a single step to yield the products then we can easily deduce the rate law from the reaction equation.

For instance, For the reaction;

2A + B → C

The rate law is

rate = k[A]²[B].

If the reaction is an elementary reaction and the equation of the reaction is balanced, then we can deduce the rate law from the balanced reaction equation.

Answer:

55.0125 grams NO2

Explanation:

So we have 80 grams of O2, first convert to moles

80 g O2 * 1 mol/32 g O2 = 2.5 mol O2

Next use the mole ratio of O2 to NO2

2.5 mol O2* 1 mol NO2/2 mol NO2=1.25 mol NO2

Since the question is asking how many grams, convert NO2 to grams

1.25 mol NO2 * 44.01 NO2/1 mol NO2= 55.0125 grams

Answer:

Remain unchanged.

Explanation:

The total number of moles of liquid remain unchanged as the some moles of species B are added to the system because specie B that is added in the liquid phase is again restored after addition. If the specie B did not restored after addition to the liquid phase so the total number of moles increases in the liquid phase so that's why we can say that the liquid phase remain unchanged.
