Baking a cake is a chemical reaction due to heat helps baking powder produce tiny bubbles of gas, which makes the cake light and fluffy. Heat also causes protein from an egg to change and make it firm.
Baking powder being CO2
NaHCO3 + NaHC4H4O4 ===> Na2C4H4O4 + CO2(g) + H2O
The overall reaction is:
Br₂(g) + 2 NO(g) ↔ 2 NOBr(g)
rate law = k [Br₂][NO]²
The first step of the overall reaction is:
NO(g) + Br₂(g) K₁⇄⇄K-1 NOBr₂(g)
rate law 1 = k₁ [Br₂][NO] or
rate law 2 = k-1 [NOBr₂]
The second step of the overall reaction is:
NOBr₂(g) + NO(g) →K₂→ 2 NOBr
rate law 3 = k₂[NOBr₂][NO]
So, rate law of overall reaction can be obtained as follows:
(rate law 1)*(rate law 3) / (rate law 2)
= [(k₁[Br₂][NO])* (K₂[NOBr₂][NO])] / k₋₁[NOBr₂]
= [k₁k₂/k₋₁][NO]²[Br₂]
So the correct answer is:
[k₁k₂/k₋₁][NO]² [Br₂]
Answer:
It is pure, anhydrous acetic acid is the correct answer.
Explanation:
- Glacial acetic acid contains very less water that the reason it is called anhydrous.
- Glacial acetic acid is a colorless, clear liquid and corrosive.
- The glacial acetic acid in the diluted form used in vegetables and food preservation,flavoring in the slice, sausage, canned fruits and also it used to treat the bacteria and fungal infections.
Answer:
0.23
Explanation:
- It is known that, the mass to mass ratio of the salt to water
= (mass of salt / mass of water)
= (25.0 g / 105.0 g)
= 0.23
