Answer from: DallasPotts7018

The volume in mL will be "800 mL".

Given that:

Mass of CO₂ = 3.59Pressure of CO₂ = 2.09 atmTemperature of CO₂ = -14°C

= 259.15 K

Atomic mass of CO₂ = 44.01 g/mol

Now,

The number of moles of CO₂ will be:

= $\frac{Mass}{Atomic \ mass}$

= $\frac{3.59}{44.01}$

= $0.081 \ moles$

By using the Ideal gas law, we get

→ PV = nRT

or,

→ $V = \frac{nRT}{P}$

By substituting the values, we get

$= \frac{0.081\times 0.0821\times 259.15}{2.09}$

$= 080 \ L$

or,

$= 0.8\times 1000$

$= 800 \ mL$

Thus the above answer is appropriate.

Answer from: adhanom12

800 ml is the volume in mL of 3.59 g CO2 of gas at 2.09 atm and -14°C.

Explanation:

Data given:

mass of the carbon dioxide gas = 3.59

pressure of the carbon dioxide gas = 2.09 atm

temperature of the carbon dioxide gas = -14 degrees OR 273.15 +(-14) = 259.15 K

atomic mass of carbon dioxide =44.01 grams/mole

R = 0.0821 L.atm/mole K

volume occupied by the gas =?

number of moles of CO2 = $\frac{mass}{atomic mass of 1 mole}$

number of moles = $\frac{3.59}{44.01}$

number of moles of carbon dioxide gas = 0.081 moles

from ideal gas law

PV = nRT

V = $\frac{0.081 X 0.0821 X 259.15}{2.09}$

V = 0.80 L is the volume of carbon dioxide gas

volume in ml = 0.8 x 1000

volume in ml= 800 ml

Answer from: Quest

water molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
