What volume will 3.50 mol of ammonia gas occupy at conditions of standard temperature and pressure?

Answers

Answer 1

Answer:

Q:

What volume will 3.50 mol of Xe gas occupy at STP?

A:

78.4 L

Explanation:

Answer 2

The volume occupied by 3.5 moles of ammonia gas at standard temperature and pressure (STP) is 78.45 L

Data obtained from the question Number of mole (n) = 3.5 moles Pressure (P) = STP = 1 atm Temperature (T) = STP = 273 KGas constant (R) = 0.0821 atm.L/Kmol Volume (V) =?

How to determine the volume

The volume of the gas at standard temperature and pressure (STP) can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

1 × V = 3.5 × 0.0821 × 273

V = 78.45 L

Mix 200 g of copper at 100 °C with 1,000 g of water at 20 °C. Final temp. = 21.42°C a) How much heat energy (q) did the water gain? b) Now solve for the specific heat (c) of copper:

Answers

Answer:

a) [tex]Q_w=5941.3J[/tex]

b) [tex]C_{Cu}=0.378\frac{J}{g\°C}[/tex]

Explanation:

Hello there!

In this case, when a hot substance is mixed with a cold one, we can evidence how the hot one is able to heat up the cold one as it cools down. Thus, the net heat flow for this problem can be set up as shown below:

[tex]Q_{Cu}+Q_{w}=0[/tex]

Whereas the heats can be written in terms of mass, specific heat and temperatures:

[tex]m_{Cu}C_{Cu}(T_F-T_{Cu})+m_{w}C_{w}(T_F-T_{w})=0[/tex]

Thus, we proceed as follows:

a. Here we compute Qw:

[tex]Q_w=1,000g*4.184\frac{J}{g\°C}(21.42\°C-20\°C) \\\\Q_w=5941.3J[/tex]

b. Now, since this heat is equal to the negative of the heat contribution of copper (as it cools down), we can compute the specific heat of copper as shown down below:

[tex]C_{Cu}=\frac{-5941.3J}{200g(21.42\°C-100\°C)} \\\\C_{Cu}=0.378\frac{J}{g\°C}[/tex]

can someone explain in detail how molar mass, Avogadro's number, and volume are all connected through moles? Im so confused :(

Answers

Answer:

See Explanation

Explanation:

By definition, 1 mole is the mass of substance (or, formula mass in grams) containing 1 Avogadro's Number (N₀ = 6.02 x 10²³) of particles. That is ...

1 mole of hydrogen atoms (H) = 1.00794 grams

1 mole of molecular hydrogen (H₂) =  2.01588 grams

1 mole of any substance = 1 formula weight in grams

1 mole = 1 Avogadro's Number (N₀) = 1 formula weight in grams

In the concept of 'gas laws' 1 mole of any (all) gas at STP conditions ( => 0°C & 1 atmosphere pressure) occupies 22.4 Liters & is known as the 'molar volume' of a gas at STP. If the temperature &/or pressure change the volume will not be 22.4 Liters.

For reactions whose coefficients are balanced to the lowest whole number values (i.e., no fractional coefficients) the equation is known as the 'standard reaction' and conditions  are assumed to be STP and the coefficients of gas phase components indicate molar volumes. Example ...

Given   N₂(g) + 3H₂(g) => 2NH₃(g)  is assumed to be at 0°C; 1 Atm pressure.

Molecular Nitrogen = 1 molar volume = 22.4 Liters of N₂(g)

Molecular Hydrogen = 3 molar volumes = 3 x  22.4 Liters of H₂(g) = 67.2 Liters of H₂(g)

Molecular Ammonia = 2 molar volumes = 2 x 22.4 Liters of NH₃(g) = 44.8 Liters of NH₃

a. It will halve to T/2.


b. It will increase to 3T.


c. It will increase to 2T.


d. It will remain the same.

Answers

Answer:

It will be halve of T

Explanation:

V1 = V

T1 = T

V2 = ½V

T2 = x

V1/T1 = V2/T2

V/T = ½V/x

Vx = ½VT

2Vx = VT

2x = T

x = ½T

What do u mean by electronic configuration? What are basic requirements while writing electronic configuration of an element (atom) ?

Answers

Yes that is right I look it up thanks for the points

The basic requirement while writing the electronic configuration of an element (atom) is its atomic number.

Explanation:

The electronic configuration of an element is the distribution of its electrons in different energy levels around the atomic nucleus.It only requires an atomic number of an element to write its electronic configuration.The atomic number is equal to the number of protons in an atom and that is equal to the number of electrons.And the filling of electrons is done according to the Aufbau principle, the electrons will be first filled in the atomic orbitals with lower orbital energy before filling the atomic orbital with higher energy.The sequence of the atomic orbitals from lower energy to higher energy is:

    [tex]1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d...[/tex]

For example:

  The atomic number of gallium is 31, its electronic configuration will be:

   [tex][Ga]=1s^2 2s^2 2p^63s^2 3p^6 4s^2 3d^{10} 4p^1[/tex]

2) Convert temperature to Kelvin
35 + 273 = 308 K

3) Use PV=nRT and solve for V
(1.18 atm)(V)=(0.0972 mol)(0.0821)(308 K)

V = (0.0972 mol)(0.0821)(308 K) / (1.18 atm)

V = 2.08 L
