A scientist is measuring the pressure that is exerted by each of the following gases in the atmosphere: carbon dioxide, oxygen,

Aleonysh [2.5K]

Answer:

Partial pressure

Explanation:

Since she's measuring the pressure exerted by each gas, it's partial pressure. If she were measuring the collective pressure, it would be total pressure.

What percentage of the mass of a carbon-12 atom is

Lynna [10]

Answer:

% of mass of electrons in C = 0.0272

Explanation:

Atomic no. of carbon = 6

So, no. of electron = 6

Mass of an electron = $\frac{1}{1836} amu$

Mass of 6 electrons = $6 \times \frac{1}{1836} = 0.003268 amu$

Mass of C = 12.0107 u

% of mass of electrons in C = $\frac{Mass\ of\ all\ electrons}{Mass\ of\ C}\times 100$

% of mass of electrons in C = $\frac{0.003268}{12.0107}\times 100=0.0272 \%$

When the temperature of a gas changes, it's volume decreases from 12 cm3 to 7 cm3 if the final temperature is measured to be 18°

ElenaW [278]

Answer:

The initial temperature is 499 K

Explanation:

Step 1: Data given

initial volume = 12 cm3 = 12 mL

Final volume = 7 cm3 = 7mL

The final temperature = 18 °C = 291 K

Step 2: Calculate the initial temperature

V1/T1 = V2/T2

⇒with V1 = the initial volume = 0.012 L

⇒with T1 = the initial volume = ?

⇒with V2 = the final volume 0.007 L

⇒with T2 = The final temperature = 291 K

0.012 / T1 = 0.007 / 291

0.012/T1 = 2.4055*10^-5

T1 = 0.012/2.4055*10^-5

T1 = 499 K

The initial temperature is 499 K

Which of the following phase changes only occurs in solids possessing vapor pressures above atmospheric pressure and at ambient

GuDViN [60]

Answer: The phase change process in which solids gets converted to gases is sublimation.

Explanation:

For the given options:

Option a: Condensation

It is a type of process in which phase change occurs from gaseous state to liquid state at constant temperature.

$Gas\rightleftharpoons Liquid$

Option b: Melting

It is a type of process in which phase change occurs from solid state to liquid state at constant temperature.

$Solid\rightleftharpoons Liquid$

Option c: Sublimation

It is a type of process in which phase change occurs from solid state to gaseous state without passing through the liquid state at constant temperature.

$Solid\rightleftharpoons Gas$

Option d: Deposition

It is a type of process in which phase change occurs from gaseous state to solid state without passing through the liquid state at constant temperature.

$Gas\rightleftharpoons Solid$

Hence, the phase change process in which solids gets converted to gases is sublimation.
