[
] value of soft drink is 0.0001mol/l when given pH is 4.
Given:
pH = 4
Needs to find: []
Formula to find: pH=−log
[]
We can put the values of pH in above formula as,
pH=−log []
4 =−log []
To calculate hydonium ion concentration, formula is as follows;
[] = 
[] = 
= 0.0001mol/l
[] value of soft drink is 0.0001mol/l

Explanation:
from the equation 1 mole of O2 will give 2 moles of H2O then 6.0 moles of O2 will give x
6.0*2 moles/ 1 mole
= 12 moles
this implies that, 6.0 moles of O2 will give = 12 moles of water
Answer:
Here malonic acid acts as a competitive inhibitor of succinate dehydrogenase
Explanation:
Malonic acid structurally resembles succinic acid as a result the enzyme succinate dehydrogenase cannot distinguish between malonic acid and succinic acid.
That"s why malonic acid interact with succinate dehydrogenase thereby blocking the catalytic activity of the later.
As this mechanism is a type of competitive inhibition that"s why increasing the concentration of substrate succinic acid can reduce the inhibitory effect of malonic acid.
Answer:
The answer to your question is 1.51 moles of PBr₃
Explanation:
Data
moles of Br = 2.27
moles of PBr₃ = x
Balanced chemical reaction
2P + 3Br₂ ⇒ 2PBr₃
Reactant Element Products
2 P 2
6 Br 6
-Use proportions to find the answer
3 moles of Br₂ ------------------ 2 moles of PBr₃
2.27 moles of Br₂ ------------------ x
x = (2.27 x 2) / 3
x = 4.54 / 3
x = 1.51 moles
