Answer:

C

Explanation:

okay, you need to look at the structures of the particles of matter in the solid, liquid and gas.

  • particles in a solid are in fixed positions, where they can only vibrate in those positions ( take a look at ice, or rather, a brick)
  • liquids have very small or rather, no spaces between them, but they can slide or rub against each other, like people in a <em>really tight</em> crowd I guess
  • gas particles have very large spaces between them and they move randomly. these exibit what's called brownian motion.
  • since water particles (and all other liquid particles) have negligible spacings and limited movement, that allows the dye particles to move from a region of high concentration to that of a low concentration. the aim for this is for the mixture/solution to reach an equilibrium, that  is the mixture must get to a point where all regions have the same concentration of the dye.

you can refer to your coursebooks :)

correct where wrong please:)

What is the final temperature when 625 grams of water at 75.0 C loses 7.96 x 10 to the fourth power J ? The specific heat of wat
IgorLugansk [536]

The final temperature : 44.5 °C

<h3>Further explanation</h3>

Heat can be formulated :

Q = m . c .Δt

Q = heat, J

m = mass, g

c = specific heat, J/gC

Δt= temperature

m= 625 g

Q=7.96 x 10⁴ J

c = 4.18 j/gC

t₁=75 C

\tt Q=m.c.\Delta t\\\\7.96\times 10^4=625\times 4.18\times (75-t_2)\\\\75-t_2=30.5\\\\t_2=44.5^oC

The oxygen atom in a water molecule A is electrically neutral. B carries a negative electrical charge. C carries a positive elec
Klio2033 [76]

Answer: The oxygen atom in a water molecule carries a negative electrical charge.

Explanation:

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.

Hydrogen bonding (H-bonding) is an intermolecular force having partial ionic-covalent character. H-bonding takes place between a hydrogen atom (attached with an electronegative atom e.g. O, N and F) and an electronegative atom (O,N and F).

In , H_2O , O is a highly electronegative atom attached to a H atom through a covalent bond. Therefore O atom gets partial negative charge and H atoms get partial positive charge.

If a molecule contains two carbon atoms and four hydrogen atoms, what can you conclude about the bond between the carbon atoms?
g100num [7]
For the given question above, I think the bond between the carbon atoms is a double bond. <span>2 carbon atoms and 4 hydrogen atoms will give an ethene, which has a C=C bond between carbon atoms. I hope this is the answer you are looking for.</span>

A gas balloon has a volume of 80.0 mL at 300K, and a pressure of 50.0 kPa. If the pressure changes to 80 kPa and the temperature
fomenos

Answer:  The new volume is 53.3 ml

Explanation:

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas =  50.0 kPa

P_2 = final pressure of gas = 80.0 kPa

V_1 = initial volume of gas = 80.0 ml

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 300K

T_2 = final temperature of gas = 320K

Now put all the given values in the above equation, we get:

\frac{50.0\times 80.0}{300}=\frac{80.0\times V_2}{320}

V_2=53.3ml

The new volume is 53.3 ml
