Flubber is fake rubber. (It rhymes)

And since it is a solid that takes up space, it is matter.

Flubber is an example of matter because it is a physical substance (solid) that occupies space.

Flubber is a gelatinous rubbery polymer that is produced by cross-linking a boron compound with polyvinyl alcohol (PVA).

A matter is any physical substance that occupies space and has inertia. Matter is composed of many types of particles that have mass and sizes and it can exist in different states such as solid, liquid and gas.

Carbon disulfide is prepared by heating sulfur and charcoal. The chemical equation is S2(g)+C(s)↽−−⇀CS2(g)????c=9.40 at 900 K Ho

Answer : The mass of $CS_2$ is, 555.028 grams

Explanation :

First er have to calculate the concentration of $S_2$ .

$\text{Concentration of }S_2=\frac{\text{Moles of }S_2}{\text{Volume of solution}}=\frac{8.08mole}{5.35L}=1.51mole/L$

Now we have to calculate the concentration of $CS_2$ .

The given balanced chemical reaction is,

$S_2(g)+C(s)\rightleftharpoons CS_2(g)$

Initial conc. 1.51 0 0

At eqm. conc. (1.51-x) (x) (x)

The expression for equilibrium constant for this reaction will be,

$K_c=\frac{[CS_2]}{[S_2]}$

Now put all the given values in this expression, we get :

$9.40=\frac{x}{(1.51-x)}$

By solving the term 'x', we get :

x = 1.365 M

Concentration of $CS_2$ = x M = 1.365 M

Now we have to calculate the moles of $CS_2$ .

$\text{Moles of }CS_2=\text{Concentration of }CS_2}\times \text{Volume of solution}=1.365mole/L\times 5.35L=7.303mole$

Now we have to calculate the mass of $CS_2$ .

Molar mass of $CS_2$ = 76 g/mole

$\text{Mass of }CS_2=\text{Moles of }CS_2}\times \text{molar mass of }CS_2}=7.303mole\times 76g/mole=555.028g$

Therefore, the mass of $CS_2$ is, 555.028 grams

Answer:

18. E. 0%

19. D. 25%

Explanation:

Question 18:

Let's use "B" to represent the dominant allele of "light blue skin", and

"b" for recessive "light green skin".

Squidward => BB - light blue skin

Squidward's bride => bb - light green skin

When they cross, they will have the following offsprings:

(BB) × (bb) - Parent

(Bb) (Bb) (Bb) (Bb) - Offspring

All the offspring would be light green skin. The dominant allele of light green skin will express itself over the recessive allele.

Therefore, the chances of Squidward and his bride having light green skin is 0%

Question 19:

Squidward's son => Bb - light blue skin

Squidward's son's bride => Bb - light blue skin

(Bb) × (Bb) - parent

(BB) (Bb) (Bb) (bb) - offspring

They will have the following offspring:

BB and Bb - light blue - 75%

bb - light green - 25%

Chance of having offspring with light green skin is 25%

Imagine that you have an ideal gas in a 6.70 L container, and that 1450 molecules of this gas collide with a square-inch area of

kakasveta [241]

Answer:

they could collide 241.66 molec / in² by increasing the volume to 40.2L

Explanation:

ideal gas:

<u>Boyle Law</u>: at constant temperature the pressure of a gas varies inversely with the volume

V1 * P1 = V2 * P2
P = F / A

∴ V1 = 6.70 L;

∴ P1 = 1450 molec / in²

∴ V2 = 40.2 L

⇒ P2 = (( 6.70 L ) * ( 1450 molec/in²)) / 40.2 L

⇒ P2 = 241.66 molec/in²
