A gas Syringe contains 42.3 milliliters of a gas at 98.15°C. Determine the volume that the gas will occupy if the temperature is decreased to -18.50°C.

Answers

Answer 1

Answer:

The volume that the gas will occupy is "29.00 mL".

According to the question,

Volume,

$V_1 = 42.3 \ mL$
$V_2 = ?$

Temperature,

$T_1 = 98.15^(\circ) C$

$= 371.15 \ K$

$T_2 = -18.50^(\circ) C$

$= 254.5 \ K$

As we know the relation,

→ $(V_1)/(T_1) = (V_2)/(T_2)$

or,

→ $V_2 = (V_1* T_2)/(T_1)$

By substituting the values, we get

→ $= (41.3* 254.5)/(371.15)$

→ $= (10765.35)/(371.15)$

→ $= 29.00 \ mL$

Thus the above answer is right.

Answer 2

Answer: V₁ = 42.3 mL

T₁ ( K ) = 98.15ºC + 273 = 371.15 K

V₂ = ?

T₂ ( K) = -18.50ºC + 273 = 254.5 K

V₁ / T₁ = V₂ / T₂

42.3 / 371.15 = V₂ / 254.5

371.15 x V₂ = 42.3 x 254.5

371.15 x V₂ = 10765.35

V₂ = 10765.35 / 371.15

V₂ = 29.00 mL

hope this helps!

It is a metal that is liquid at room temperature. It's a poisonous mercury. it forms when bacteria react with mercury in water, soil, or plants. It's been used to preserve grain that is fed to animals. It's used in fluorescent lights, batteries, polyvinyl chloride and latex paint.

What is the temperature of 1.2 moles of Helium gas at 1950 mm Hg if it occupies 15,500 ml of volume?

Answers

Answer:

$T=404.16K=13.1^oC$

Explanation:

Hello,

In this case, we use the ideal gas equation to compute the requested temperature as shown below and considering the proper units:

$PV=nRT\nT=(PV)/(nR)=(1950mmHg*(1atm)/(760mmHg)*15500mL*(1L)/(1000mL) )/(1.2mol*0.082 (atm*L)/(mol*K) ) \nT=404.16K=13.1^oC$

Best regards.

1950

1950mmHg and simplify.

The temperature at which a liquid becomes a solid is the:A. Boiling point
B. Density
C. Freezing point
D. Solubility

Answers

The point where a liquid becomes a solid is its freezing point. The freezing point of water, for example, is 0°C, at which point it turns to ice.

The answer is Freezing point Because It would be 0 degrees Celsius is it freezing point.

Which development was a direct result of thebaby boom that followed World War II?
(1) decrease in school construction
(2) increase in suburbanization
(3) decline in crime rates
(4) rise in immigration

Answers

Many countries experienced the baby boom after the World War II ended. The baby boom resulted to the increase in suburbanization which is number 2. The more people/babies born, the more houses are needed. The countries who experienced the baby boom were not large enough to cater the population so mass developments happened.

the development that became a direct result of thebaby boom that followed World War II would be: increase in suburbanizationBaby boomers makes the urban city became a lot more crowded and often caused heavy traffic every single day. Because if this, many people decided to live in a suburban area while commuting to work in the city at the same time

Which of the following is the most electronegative element? a. He
b. I
c. N
d. O
e. C

Answers

none of these; the most electronegative element is fluorine because an atom of fluorine needs an additional electron to join it's outer membrane, so the atom can achieve stability.

a flourine atom on its own is always a negative ion.
