Well you’ll know it’s scientifically sound if enough definitive research and tests have been done AND show good results. Example:I could say that eating ants can cure cancer but if it’s not tested with good results it’s not scientifically sound

What volume of CH4(g), measured at 25oC and 745 Torr, must be burned in excess oxygen to release 1.00 x 106 kJ of heat to the su

anastassius [24]

Answer:

$V=27992L=28.00m^3$

Explanation:

Hello,

In this case, the combustion of methane is shown below:

$CH_4+2O_2\rightarrow CO_2+2H_2O$

And has a heat of combustion of −890.8 kJ/mol, for which the burnt moles are:

$n_{CH_4}=\frac{-1.00x10^6kJ}{-890.8kJ/mol}= 1122.6molCH_4$

Whereas is consider the total released heat to the surroundings (negative as it is exiting heat) and the aforementioned heat of combustion. Then, by using the ideal gas equation, we are able to compute the volume at 25 °C (298K) and 745 torr (0.98 atm) that must be measured:

$PV=nRT\\\\V=\frac{nRT}{P}=\frac{1122.6mol*0.082\frac{atm*L}{mol*K}*298K}{0.98atm}\\\\V=27992L=28.00m^3$

Best regards.

Definition of the density of the sun?

WARRIOR [948]

Answer:

"The core of the Sun extends from the center to about 20–25% of the solar radius. It has a density of up to 150 g/cm3 (about 150 times the density of water) and a temperature of close to 15.7 million kelvins (K)"

Please help me with this question please just help me with what is this is or synthesis singlereplacement

andrew11 [14]

Answer:

1) Combustion

2)Synthesis

3)Single Replacement

4)Decomposition

5)Double Replacement

6)Synthesis

7)Double Replacement

8)Single Replacement

9)Combustion

10)Decomposition

Explanation:

Remeber, decomposisition is breaking things apart, synthesis is building them, cobusion will always make water and CO2 and will always burn O2, single replacemnt will have 1 thing replaced (single) and double replacement will have 2 things replaced (double).

Hope this helps!

Sodium bicarbonate is used to neutralize the remaining HCl at the end of the reaction. The initial products of this reaction are

V125BC [204]

Answer:

Kindly check explanation section.

Explanation:

Since, the question requires the chemical reaction to be written in lewis for the the processes involved in this particular Question/problem that is to say the neutralization process and the decomposition process. The lewis structure is given in the attached picture.

For the first process; Sodium bicarbonate reacts with HCl to produce the carbonic acid and a salt, known as Sodium chloride.

Na2CO3 + 2HCl ----------> 2NaCl + H2CO3.

The second process shows the decomposition of Carbonic acid into carbon dioxide and water.
