Polyatomic ion: a covalently bonded group of atoms that has a positive or negative charge and acts as a unit.
Answer:
K3PO4
Explanation:
Recall that colligative properties depends on the number of particles present. The greater the number of particles present, the greater the degree of colligative properties of the solution. Let us look at each option individually;
SrCr2O7-------> Sr^2+ + Cr2O7^2- ( 2 particles)
C4H11N (not ionic in nature hence it can not dissociate into ions)
K3PO4-------> 3K^+ + PO4^3- (4 particles)
Rb2CO3-------> 2Rb^+ + CO3^2- (3 particles)
Hence K3PO4 has the greatest number of particles and will display the greatest colligative effect.
Answer:
B; Photosynthesis
Explanation:
Here, we want to get the process that helps produce glucose and oxygen
The process here is called Photosynthesis
It is the process by which green plants use chloropyhll iin them, catalyzed by sunlight to produce energy in form of glucose
