The height of a column of mercury in a closed-end manometer is 13.2 cm. What is the pressure of the gas in torr

Chemistry
1 answer:
AlladinOne [14]2 years ago
5 0

Answer:

P_{gas}=131.96torr

Explanation:

Helo,

In this case, the pressure must be computed as follows:

P_{gas}=gh\rho _{Hg}

Which is using the density of mercury (13.6 g/mL) and its height, thus, we obtain (using the proper units):

P_{gas}=9.8\frac{m}{s^2}*(13.2cm *\frac{1m}{100cm} )*(13.6\frac{g}{cm^3}*\frac{1kg}{1000g}*\frac{1x10^6cm^3}{1m^3} )\\\\P_{gas}=17592.96Pa*\frac{760torr}{101325Pa} \\\\P_{gas}=131.96torr

Best regards.

Electronic configurations and charges of the ions<br>in lithium fluoride?​
BARSIC [14]

Answer:

Explanation:

The electronic configuration of a lithium atom is 2.1 and that of a fluorine atom is 2.7

an atom of lithium donates an electron to an atom of fluorine to form an ionic compound. The transfer of the electron gives the lithium ion a net charge of +1, and the fluorine ion a net charge of -1.

Explain how you would find the number of moles of carbon in 4.5 kg of carbon.
UkoKoshka [18]
In a simplified version, check the number carbon atoms present and multiply by its relative atomic mass. Later divide by the given mass (4.5 x 1000 = 4500g) and you’ll get the number of mole of carbon

A container of oxygen has a volume of 30.0 mL and a pressure of 72.5 psi. If the pressure of the oxygen gas is reduced to 28 psi
OLga [1]

Answer:

THE NEW VOLUME OF THE OXYGEN GAS AT 28 PSI FROM 72.5 PSI IS 0.078 L.

Explanation:

Initial volume of the oxygen in the container = 30.0 mL = 30 / 000 L = 0.03 L

Initial pressure of the oxygen = 72.5 psi =  1 psi = 6890 pascal

Final pressure = 28 psi

Final volume = unknown

First convert the mL to L and since both pressures are in similar unit that is psi; there is no need converting them to pascal or other standard unit of pressure. They cancel each other out.

This question follows Boyle's equation of gas laws and mathematically it is written as:

P1 V1 = P2 V2

Re-arranging by making P2 the subject of the formula, we have:

V2 = P1 V1 / P2

V2 = 72,5 * 0.03 / 28

V2 = 2.175 /28

V2 = 0.0776 L

The new volume of the oxygen gas at a change in pressure from 72.5 psi to 28 psi is 0.078 L.

You need to determine the mass of an aqueous solution. You determine the mass of your 10.0 mL graduated cylinder to be 23.731 g.
Amanda [17]

Answer: 0.86g/mL

Explanation:

Mass of empty cylinder = 23.731g

Mass of cylinder + liquid = 26.414g

Mass of the liquid = 26.414 — 23.731

= 2.683g

Volume of the liquid = 3.12mL

Density = Mass / volume

Density = 2.683g / 3.12mL

Density = 0.86g/mL

How does convection occur in the troposhere ​
adell [148]

Answer:The surface heated air expands as it warms, becomes less dense than surrounding cooler air and rises as buoyant and turbulent bubbles. This is convection and is the main process by which the troposphere mixes and heats. Although convection stirs and mixes the troposphere, the higher it is the colder it becomes.

Explanation: Read this and you'll get your answer~! I hope i helped you~! Have an GREAT day too~! <\3
