Answer:

Science tells us that light is the reason we are able to see objects. Without light, we wouldn't be able to process the visible world. ... The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, infrared light, ultraviolet light, X-rays, and gamma rays.

Explanation:

i hope this is right :)

If you are playing pool and hit the cue ball at the stationary 8 ball, what should happen?

jolli1 [7]

Answer If a ball goes into a pocket and bounces back on to the playing surface, it is not considered pocketed. If it is the 8-ball, it is not a win. If it is the cue ball, it is not a scratch.

For this heterogeneous system 2 A ( aq ) + 3 B ( g ) + C ( l ) − ⇀ ↽ − 2 D ( s ) + 3 E ( g ) the concentrations and pressures at

maw [93]

Answer:

$2.55*10^{11$

Explanation:

Equation for the heterogeneous system is given as:

$2A_{(aq)} + 3 B_{(g)} + C_{(l)}$ ⇄ $2D_{(s)}$ $+$ $3E_{(g)}$

The concentrations and pressures at equilibrium are:

$[A] = 9.68*10^{-2}M$

$P_B = 9.54*10^3Pa$

$[C]=14.64M$

$[D]=10.11M$

$P_E=9.56*10^4torr$

If we convert both pressure into bar; we have:

$P_B = 9.54*10^3Pa$

$P_B = (9.54*10^3)*\frac{1}{10^5} bar$

$P_B=9.54*10^{-2}bar$

$P_E=9.56*10^4torr$

1 torr = 0.001333 bar

$9.54*10^4 *0.001333 = 127.5 bar$

$K=\frac{[P_E]^3}{[A]^2[P_B]^3}$

$K=\frac{(127.5)^3}{(9.68*10^{-2})^2(9.54*10^{-2})^3}$

$K=2.55*10^{11$

The volume of a gas is 650. mL at 1.14°C. What will the volume be a 75.0°C?

tia_tia [17]

<u>Answer:</u> The final volume of the gas is 825.12 mL

<u>Explanation:</u>

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=650mL\\T_1=1.14^oC=(1.14+273)K=274.14K\\V_2=?mL\\T_2=75^oC=(75+273)K=348K$

Putting values in above equation, we get:

$\frac{650mL}{274.14K}=\frac{V_2}{348K}\\\\V_2=\frac{650\times 348}{274.14}=825.12mL$

Hence, the final volume of the gas is 825.12 mL
