Answer:
Explanation:
1)This reaction is an acid base reaction. Baking soda is made up of sodium bicarbonate has it's PH above 7,while the Buttermilk contains some fatty acids with it's PH below 7, neutralization would occur when mixed together, and the pH of the mixture must be close to 7 which is neutral pH.
2) PH of 7(Neutral PH)
3)Self-raising flour has baking powder as one of its constituents. It also cotains cream of tartar, bicarbonate soda as well as calcium aluminium phosphate, the carbon dioxide from Bicarbonate of soda is released when reaction with acid takes place, then the Cream of tartar turns to tartaric acid when it is mosturized , then the reaction between them will produce bubbles of carbon dioxide in the cake, causing the cake to rise.
4)It makes a good household cleaner because it react with organic chemicals such as oil or grease then break them down like without attacking the metals that is attached to them.Bases contain particles called hydroxide ions. The higher the amount of hydroxide ions present in a base , the stronger it is.
5) The harsh acid or bike in the stomach creates a burning sensation in the back of your throat which irritate the food pipe line. Ifthe acid reflux is severe, it's reffered to as gastroesophageal reflux
Answer:
≈ 708
Explanation
Here we have equation as:
4 Al + 3 O₂ → 2 Al₂O₃
As we know:
No of moles = Mass/ Molar mass
Here, Mass is 375 g and Molar mass is 27 gms, so no. of moles of Al will be:
=375 g /27 g/mol
= 13.889 mol
About mole ratio, we can see that for 4 moles of Al , 2 moles of Al2O3 are formed, so for 13.889 moles of Al, 13.889 mol ÷ 2 =6.944 moles of Al₂O₃ will be formed.
As we know:
Mass= No of moles/Molar mass
Mass of Al₂O₃ = 6.944 mol × 102 g/mol
= 708.288 g
Hope it helps!
Explanation:
It is known that relation between 
, 
, and pH is as follows.
![E_{cell} = E^{o}_{cell} - (\frac{0.0591}{n}) \times log[H^{+}] ](https://tex.z-dn.net/?f=E_%7Bcell%7D%20%3D%20E%5E%7Bo%7D_%7Bcell%7D%20-%20%28%5Cfrac%7B0.0591%7D%7Bn%7D%29%20%5Ctimes%20log%5BH%5E%7B%2B%7D%5D%0A)
Also, it is known that for hydrogen is equal to zero.
Hence, substituting the given values into the above equation as follows.
0.238 V = 0 - (\frac{0.0591}{1}) \times log[H^{+}]
[/tex]
![-log[H^{+}]](https://tex.z-dn.net/?f=-log%5BH%5E%7B%2B%7D%5D)
= 4.03
![[H^{+}]](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D)
= antilog 4.03
= 3.5
As, pH = .
Thus, we can conclude that pH of the given unknown solution at 298 K is 3.5.
Answer:
Most metals have <u>luster</u> which means they <u>reflect</u> light
Explanation:
When light, which is made up of energetic photons, comes in contact with the surface of a metal, it is absorbed due to the corresponding energy gaps present between the metal orbital. The absorbed photons results in the raising of the energy levels of electrons within an atom of the metal which later drop back to a lower energy level and re-emit the photons which can now be observed as the metallic luster.
