Answer:
A positron is a subatomic particle with the same mass as an electron and a numerically equal but positive charge.
Answer;
Anaerobic respiration is used commercially in the production of beer, wine, bread, yogurt, and cheese.
Explanation;
-Anaerobic respiration is a type of respiration that does not use oxygen. It is used when there is not enough oxygen for aerobic respiration.There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.
-The carbon dioxide produced as a by-product when yeast perform alcoholic fermentation on the sugar in the bread mix is the gas that causes dough to rise. The sugars in produce like barley, grapes and other grains and fruits is what allows yeast to produce the bubbles and alcohol in beer, wine and other liquors.
I’m not sure but i think blue
Answer:
H2CO3 = 2H+ + CO3-
Explanation:
It is simply what carbonic acid breaks down into when placed in water. Since carbonic acid is made up of H and CO3, these are the products.
Answer is: pH of aniline is 9.13.<span>
Chemical reaction: C</span>₆H₅NH₂(aq)+
H₂O(l) ⇌ C₆H₅NH₃⁺(aq) + OH⁻(aq).
pKb(C₆H₅NH₂) = 9.40.
Kb(C₆H₅NH₂) = 10∧(-9.4) = 4·10⁻¹⁰.
c₀(C₆H₅NH₂) = 0.45 M.
c(C₆H₅NH₃⁺) = c(OH⁻) = x.
c(C₆H₅NH₂) = 0.45 M - x.
Kb = c(C₆H₅NH₃⁺) · c(OH⁻) / c(C₆H₅NH₂).
4·10⁻¹⁰ = x² / (0.45 M - x).
Solve quadratic equation: x = c(OH⁻) = 0.0000134 M.
pOH = -log(0.0000134 M.) = 4.87.
pH = 14 - 4.87 = 9.13.
