Denser salt water makes the eggs to float in the water.

<u>Explanation: </u>

Egg will always sink in water, as egg is denser than water.

But we can make it to float by means of adding excess salt to the water. Adding more salt to water makes it as denser than egg. Denser water makes less dense egg to float in water.

So, making the water as denser one leads to the floating of egg in the water.

A liquid has a density of 4.26g/ml. It has a mass of 2.2g. What is the volume of the liquid?

serg [7]

Answer:

Volume = .5164 ml

Explanation:

These are the equations you need to learn.

$Density = \frac{mass}{volume}$

$Volume = \frac{Mass}{Density}$

$Mass = Density * Volume$

Apply these concepts to your problem

$4.26 g/ml = \frac{2.2g}{x}$

$V = \frac{2.2g}{4.26g/ml}$

Divide 2.2/4.26

$V = 0.5164319248826291$

$Volume = .5164ml$

blsea [12.9K]

Answer:

Explanation:

100 minutes is 5 half lives ( 100 min/20 min/half life)

= (1/2 )^5

1 x 10^20 * (1/2)^5 = 3.125 x10^18 molecules

A galvanic cell consists of a Cu(s)|Cu2+(aq) half-cell and a Cd(s)|Cd2+(aq) half-cell connected by a salt bridge. Oxidation occu

Kryger [21]

Answer:

$Cd(s)|Cd^{2+}(aq) || Cu^{2+}(aq)|Cu(s)$

Explanation:

A galvanic cell is composed of two electrodes immersed in a suitable electrolyte and connected via a salt bridge. One of the electrodes serves as a cathode where reduction or gain of electrons takes place. The other half cell functions as an anode where oxidation or loss of electrons occurs.

The representation is given by writing the anode on left hand side followed by its ion with its molar concentration. It is followed by a salt bridge. Then the cathodic ion with its molar concentration is written and then the cathode.

As it is given that cadmium acts as anode, it must be on the left hand side and copper must be on right hand side.

$Cd(s)|Cd^{2+}(aq) || Cu^{2+}(aq)|Cu(s)$
