Calculate the mass of sodium acetate trihydrate required to make 100. ml of a 0.100 m solution. as part of your preparation for

vova2212 [387]

Required moles of CH₃COONa.3H₂O = Molarity x Volume of solution in L

= 0.100 M x (100.0 mL)

= 0.100 M x 0.100 L

= 0.01 mol

Required mass of CH₃COONa.3H₂O = Required moles x Molar mass

= 0.01 mol x (136.08 g / mol) = 1.3608 g

For the simple decomposition reactionAB(g)→ A(g) + B(g)Rate =k[AB]2 and k=0.2 L/mol*s . How long will it takefor [AB] to reach 1

mixer [17]

Answer:

6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.

Explanation:

$Rate = k[AB]^2$

The order of the reaction is 2.

Integrated rate law for second order kinetic is:

$\frac{1}{[A_t]} = \frac{1}{[A]_0}+kt$

Where, $[A_0]$ is the initial concentration = 1.50 mol/L

$[A_t]$ is the final concentration = 1/3 of initial concentration = $\frac{1}{3}\times 1.50\ mol/L$ = 0.5 mol/L

Rate constant, k = 0.2 L/mol*s

Applying in the above equation as:-

$\frac{1}{0.5} = \frac{1}{1.50}+0.2t$

$\frac{1}{1.5}+0.2x=\frac{1}{0.5}$

$t = 6.66\ s$

<u>6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.</u>

Write at least 5 different sentences each adjective describes: crystal_____, soluble_____, hard_________, solid_______,

rewona [7]

Answer:

Definite shape, definite volume, definite melting point, high density, incompressibility, and low rate of diffusion.
The most obvious physical properties of a liquid are its retention of volume and its conformation to the shape of its container.
When a liquid substance is poured into a vessel, it takes the shape of the vessel, and, as long as the substance stays in the liquid state, it will remain inside the vessel.
There are four types of crystalline solids: ionic solids, molecular solids, network covalent solids and metallic solids.
There are two types of liquid-liquid mixtures. They are: Homogeneous Liquid-Liquid Mixture. This is a type of liquid-liquid mixture whereby the two substances mix completely to from a single substance.
