Two teaspoons of salt are added to a glass of water which is then stirred until no more salt grains can be seen. Two more teaspo

ons are added and stirring is continued, but the salt grains are still evident in the glass and settle to the bottom. After the addition of the last two teaspoons of salt the solution is

True

REASON: All gas mixtures are homogeneous, hence all gas mixtures are solutions. Air is an example. Air is only one phase--the gas phase. All the molecules, whatever the source, behave as gas molecules. The molecules themselves may have come from gaseous substances, liquid substances, or solid substances. Whatever the source of the constituents, this gaseous solution–air–is in a single, homogeneous phase. As with other solutions, the constituents of air may be separated by phase changes.

kvv77 [185]

Answer:

The gas volume remains constant

Explanation:

The volume stayed constant however the balloon may seem to have shriveled or deflated upon walking outside due to the helium condensing in  the cooler climate.

Find the volume occupied by 4.00 g of helium gas at <br> 25.0o C and 1.18 atm of pressure.
Triss [41]

Answer: 41.46 L

Explanation:

La ecuación que describe  relación entre presión, volumen,  temperatura y la cantidad (en moles)

de un gas ideal es:   PV = nRT

Donde:  P = Presión absoluta ,  V= Volumen  , n = Moles de gas , R = Constante universal de los gases ideales,  T = Temperatura absoluta,

R = 0.082 L. atm/mol. °K

V = nRT/P

Calculanting n

n = mass/ molecular mass

<h3>n = 4 g / 2g. mol⁻¹</h3><h3>n = 2 mol</h3><h3>T =25⁰ + 273 ⁰K = 298 ⁰K</h3><h3>V = (2 mol ₓ0.082 L. atm / mol.°K x 298 ⁰K) / 1.18 atm = 41.46 L</h3>

88.5 mol of P4O10 contains how many moles of P?
Dennis_Churaev [7]
Looking at the formula, each mol of P4O10 contains 4 mol of P, so 
(58.5 mol P4O10) x (4 mol P/ 1 mol P4O10) = 234 mol

The brightness of a star is most dependent on the star's...Explain why.
gulaghasi [49]
I would say the answer is A - a stars mass

The majority of stars in the galaxy, including our Sun, Sirius and Alpha Centauri A and B are all main sequence stars.


Mass is the key factor in determining the lifespan of a main sequence star, its size and its luminosity ( brightness)




Two characteristics define brightness: luminosity and magnitude. Luminosity is the amount of light that a star radiates. The size of the star and its surface temperature determine its luminosity. Apparent magnitude of a star is its perceived brightness, factoring in size and distance, while absolute magnitude is its true brightness irrespective of its distance from earth.
