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:
A
Explanation:
I would say A because the sun makes energy right so if you are looking for an arrow or arrows I would say A I hope this helps!! and have a great day or night
Answer:
moles B = 2.32 moles
Explanation:
In this case, we can assume that both gases are ideals, so we can use the expression for an ideal gas which is:
PV = nRT
From here, we can calculate the total moles (n) that are in the container, and then, by difference, we can calculate how much we have of gas B.
For this case, we will use R = 0.082 L atm / mol K. Solving for n:
n = PV/RT
n = 5 * 20 / 0.082 * 303
n = 4.02 moles
If we have 4.02 moles between the two gases, and we have 1.70 from gas A, then from gas B we simply have:
Total moles = moles A + moles B
moles B = Total moles - moles A
moles B = 4.02 - 1.70
moles B = 2.32 moles
We have 2.32 moles of gas B
