Answer:
See explanation
Explanation:
A substance is only soluble in water if it is composed of ions or polar groups which are capable of interaction with water.
Salt is composed of ions which are easily solvated by the dipoles of water molecule. Sucrose is composed of polar groups capable of interaction with water. This accounts for the solubility of sucrose (sugar) in water. Sugar is a covalent molecule but is composed of polar groups while salt is composed of ionic bonds.
Hence salt and sugar are both soluble in water for the reasons described above.
Answer:
Original volume=3L
Explanation:
Assuming the gas in the ballon is ideal and the temperature does not vary with height we have the gas law as
PV=nRT
Here RHS is constant in both the conditions which means
PV=constant
Given P1=1 atm V1=V P2=0.75atm V2=4L
P1V1=P2V2

V=3L
The initial volume of the gas is 3L
Answer:
During MITOSIS, the parent, diploid (2n), cell is divided to create two identical, diploid (2n), daughter cells. ... After cytokinesis, the ploidy of the daughter cells remains the same because each daughter cell contains 4 chromatids, as the parent cell did.

Cobalt(II) has a charge of 2+
Phosphate has a charge of 3-
Because it's an ionic compound, you will need to take the charge and make them subscripts.
The formula for cobalt(II) phosphate is
Co₃(PO₄)₂
Your answer is
