6832 J of heat energy is applied to 5.9 mol of water. If the original temperature of the water was 18.60C, the final temperature

sineoko [7]

Answer: The final temperature of the water will be $34.0^0C$

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

$Q=m\times c\times \Delta T$

Q = Heat absorbed= $6832$ Joules

m= mass of water = $5.9mol\times 18g/mol=106.2g$

c = specific heat capacity = $4.184J/g^0C$

Initial temperature of the water = $T_i$ = $18.6^0C$

Final temperature of the water = $T_f$ = ?

Putting in the values, we get:

$6832=106.2\times 4.184\times (T_f-18.6)$

$T_f=34.0^0C$

The final temperature of the water will be $34.0^0C$

What are some compare and contrasts between Terrestrial Planets and Gas Planets?

dexar [7]

<h3><u><em>The different types of planets would be the gas giants all have more than 12 moons whereas the terrestrial planets all have less than 3 moons. A second difference is that that gas giants are all larger in diameter than the terrestrial planets. Also the Gas Giants are usually bigger than Terrestrial Planets. Gas Giants also have thicker atmospheres, and have gaseous surfaces. Terrestrial planet tend to be smaller, and have solid surfaces. In our solar system, Mercury, Venus, Earth (home), and Mars are Terrestrial planets.I am glad to help anytime ...Brainliest?</em></u></h3>

Mr. Holmes and Mrs. Nogaki are having a good old fashioned Baby Back Ribs BBQ contest and are arguing over who’s BBQ produces le

ExtremeBDS [4]

Answer:

Mrs. Nogaki is right because Mr. Holmes’s BBQ produces 3x more CO2 for each mole of fuel burned.

Explanation:

Now Mrs. Nogaki has already figured out the chemical combustion reaction behind the operation of her BBQ. It is pertinent to reproduce it here.

CH4(g) + 2O2(g)→CO2(g) +2H2O(g)

She already has this figured out but Mr. Holmes doesn't have any chemical reaction equation to back his claims. Let us help him with the correct combustion equation for propane.

C3H8(g) + 5O2(g) + 3CO2(g) + 4H2O(g)

We can clearly see from the reaction equation that Mr. Holmes BBQ produces three times more carbon IV oxide than Mr. Nogaki's BBQ so Mr. Nogaki was right in her claim after all.

Hence the answer!
