5 0

Write out the equation:
AgNO3(aq)+K2SO4(aq) --> Ag2SO4(s)+K2(NO3)...

Balance the equation:
2 AgNO3(aq)+K2SO4(aq) --> Ag2SO4(s)+K2(NO3)2...

Remember to keep molecules intact when you write out the ions.
(2Ag+)+(2NO3-)+(2K+)+(SO42-) --> (Ag2SO42
Cancel out all the spectator ions. These are ions that watch the reaction that didn't change. For this problem 2K+ & 2NO3- are the spectator ions.

You are left with your net ionic equation of
2Ag+(aq)+SO42-(aq)-->Ag2SO4(s)

A certain substance X has a normal freezing point of -6.4 C and a molal freezing point depression constant Kf= 3.96 degrees C.kg

Brut [27]

Answer: $1.0\times 10^2g$

Explanation:

Depression in freezing point is given by:

$\Delta T_f=i\times K_f\times m$

$\Delta T_f=T_f^0-T_f=(-6.4-(13.6))^0C=7.2^0C$ = Depression in freezing point

i= vant hoff factor = 1 (for non electrolyte like urea)

$K_f$ = freezing point constant = $3.96^0C/m$

m= molality

$\Delta T_f=i\times K_f\times \frac{\text{mass of solute}}{\text{molar mass of solute}}\times \text{weight of solvent in kg}}$

Weight of solvent (X)= 950 g = 0.95 kg

Molar mass of non electrolyte (urea) = 60.06 g/mol

Mass of non electrolyte (urea) added = ?

$7.2=1\times 3.96\times \frac{xg}{60.06 g/mol\times 0.95kg}$

$x=1.0\times 10^2g$

Thus $1.0\times 10^2g$ urea was dissolved.

In Mitosis, do new cells have different DNA or the same DNA?

Otrada [13]

Answer: With few exceptions, the mitotic process ensures that this is the case. Therefore, mitosis ensures that each successive cellular generation has the same genetic composition as the previous generation, as well as an identical chromosome set.
