What is the chemical formula for ammonium sulfide

2 answers:

8 0

The chemical formaula for ammonium sulfide would be ammonium (NH₄⁺) plus sulfur (S⁺²). So now what we would do is figure out how to balance the charges (to create a stable molecule) using our knowledge of valence electrons. Or we can use a shortcut and switch the subscripts of the two atoms so it looks like this: (NH₄)₂S.

(We used a shortcut, but essentially what we did was figure out how many of each atom/ion we would need to create a balanced molecule.)

Two bulbs are connected by a stopcock. The large bulb, with a volume of 6.00 L, contains nitric oxide at a pressure of 0.850 atm

alekssr [168]

Answer:

(I). The gases are present at the end of the experiment are O₂ and NO₂

(II). The pressure of O₂ is 0.158 atm.

The pressure of NO₂ is 0.681 atm

The Pressure of NO is zero.

Explanation:

Given that,

Volume of large bulb = 6.00 L

Pressure = 0.850 atm

Volume of small bulb = 1.50 L

Pressure = 2.50 atm

Temperature = 22°C = 295 K

We need to calculate the moles in NO

Using formula of moles

$n=\dfrac{PV}{RT}$

Put the value into the formula

$n=\dfrac{0.850\times6.00}{0.0821\times295}$

$n=0.211\ moles$

We need to calculate the moles in O

Using formula of moles

$n=\dfrac{PV}{RT}$

Put the value into the formula

$n=\dfrac{2.50\times1.50}{0.0821\times295}$

$n=0.155\ moles$

The balance equation for the reaction is

$2NO+O_{2}\Rightarrow 2NO_{2}$

So, The gases are present at the end of the experiment are O₂ and NO₂

We need to calculate the remaining moles of O₂

Using formula for remaining moles

Moles of O₂ remaining = $0.155-\dfrac{0.211}{2}$

$Moles\ of \ O_{2}\ remaining =0.049\ moles$

Moles of NO₂ = 0.211 moles

Total volume $V=V_{l}+V_{s}$

Put the value into the formula

$V=6.00+1.50$

$V=7.5\ V$

(2). If the gas was consumed completely

We need to calculate the pressure of O₂

Using formula of pressure

$P=\dfrac{moles\times R\times T}{V}$

Put the value into the formula

$P=\dfrac{0.049\times0.0821\times295}{7.5}$

$P=0.158\ atm$

We need to calculate the pressure of NO₂

Using formula of pressure

$P=\dfrac{moles\times R\times T}{V}$

Put the value into the formula

$P=\dfrac{0.211\times0.0821\times295}{7.5}$

$P=0.681\ atm$

If the gas was consumed completely

Then, Pressure of NO is zero.

Hence, (I). The gases are present at the end of the experiment are O₂ and NO₂

(II). The pressure of O₂ is 0.158 atm.

The pressure of NO₂ is 0.681 atm

The Pressure of NO is zero.

The surface tension of water _is because it's molecules form_.

Furkat [3]

Answer: water has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds. That means a drop of water will ´´want´´ to have the smallest possible surface area. The shape that has the smallest possible area for a given area is a sphere.

Explanation:hope this helps!

if the amount of gas is decreased and the temperature and pressure stay constant what will be the effect on its volume

Leviafan [203]

Answer:

Volume will decreased by decreasing the amount of gas.

Explanation:

The amount of gas and volume are directly related to each other. By decreasing the amount of gas volume will decrease by keeping the temperature and pressure constant.

Mathematical expression:

V ∝ n

V = Kn

we put the K by removing the sign of proportionality.

K = proportionality constant

n = amount of gas

V = volume of gas

The volume- amount relation is called Avogadro law.

By increasing the amount of gas volume will also goes to increase.
