Answer:
Solid : The intermolecular space is very less
Liquid : The intermolecular space is fairly more than in solids
Solid : It has a fixed shape
Liquid : It has a fixed volume but shape changes according to where it is placed
Solid : eg : Books
Liquid : eg : water
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
6 CO₂ + 6 H₂O (chlorophyll + sunlight) ⇒ C₆H₁₂O₆ + 6 O₂
the reaction takes place in presence of sunlight and chlorophyll ..
CO₂ is oxidized and forms Glucose . And oxygen is evolved in this process.
Answer:
d
Explanation:
it's the only one that seems to make sense
B- plants that hold the soil due off
Standard reduction potential of Cd2+ = -0.403 v
Standard reduction potential of Cr3+ = -0.74 v
Here, reduction potential of Cd2+ is higher as compared to Cr3+. Hence, it will preferentially undergo reduction.
The electrochemical cell is represented as
Cr/Cr3+// Cd2+/Cd
Now, standard EMF of cell = E = ECd2+/Cd - ECr3+/Cr
= - 0.403. - (-0.74)
= 0.337 v
