Answer:
The increase of prey
Explanation:
Without predators in the ecosysten prey population would increase
A circuit with many paths for the current to travel through and not simply one is classified as a parallel circuit. Here the circuit can have many loops of resistors or light bulbs that can be attached.
Answer:
(a) Polarity of phase: 1. Stationary phase is polar
b) Eluent strength of solvent: 1. Increases as solvent becomes more polar
c) Nature of solutes.1. Polar
d) Nature of solute interaction:2. More soluble in mobile phase as the polarity of the mobile phase decreases
e) Polarity of phases: 1. Stationary phase is polar
f) Eluent strength of solvent: 1. Increases as solvent becomes more polar.
g) Nature of solutes: 1. Polar
h) Nature of solute interaction: 2. More soluble in mobile phase as the polarity of the mobile
Explanation:
True, because diatomic elements (H2, O2, F2, Br2, I2, N2, Cl2) consist of only one element but are molecules with covalent bonds.
Answer:
The molarity will be "0.43 M" and molality will be "0.43 m".
Explanation:
Given that:
mass of NaCl,
= 25 g
Volume of solution,
= 1 L
Density of solution,
= 1 gm/cm³
Now,
The weight of solvent will be:
= 
= 
= 
The mole of NaCl will be:
= 
= 
= 
hence,
The molarity will be:
= 
= 
= 
The molality will be:
= 
=
=
