Answer:

1.22 × 10^22 H atoms

Explanation:

From this question, TNT has the chemical formula: C-H5N306. The number of nitrogen atoms in the TNT substance is said to be 7.30 × 10^21 atoms.

The number of hydrogen atoms in the same TNT substance can be got using mole ratio. Based on the chemical formula, the mole ratio of hydrogen to nitrogen is 5:3 i.e. H5N3.

This means that;

Number of atoms of hydrogen = 5/3 of the number of atoms of nitrogen.

Hence, number of H atoms = 5/3 × 7.30 × 10^21

number of H atoms = (7.30 × 5/3) × 10^21

number of H atoms = (36.5/3) × 10^21

number of H atoms = 12.1666 × 10^21

number of H atoms = 1.2166 × 10^22 atoms.

Approximately, number of H atoms in TNT is 1.22 × 10^22 atoms.

Determine the density of gold if a 475.09g sample occupy a space of 24.6cm^3
Ira Lisetskai [31]

Answer:

The answer is

<h2>19.31 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}

From the question

mass of gold = 475.09g

volume = 24.6 cm³

The density of the gold is

density =  \frac{475.09}{24 .6}  \\  = 19.3126016...

We have the final answer as

<h3>19.31 g/cm³</h3>

Hope this helps you

15.0 moles of gas are in a 8.00 L tank at 22.3 ∘C∘C . Calculate the difference in pressure between methane and an ideal gas unde
leva [86]

Answer:

\Delta P=4.10atm

Explanation:

Hello!

In this case, since the ideal gas equation is used under the assumption of no interaction between molecules and perfectly sphere-shaped molecules but the van der Waals equation actually includes those effects, we can compute each pressure as shown below, considering the temperature in kelvins (22.3+273.15=295.45K):

P^{ideal}=\frac{nRT}{V}=\frac{15.0mol*0.08206\frac{atm*L}{mol*K}*295.45K}{8.00L}=45.5atm

Next, since the VdW equation requires the molar volume, we proceed as shown below:

v=\frac{8.00L}{15.0mol}=0.533\frac{L}{mol}

Now, we use its definition:

P^{VdW}=\frac{RT}{v-b} -\frac{a}{v^2}

Thus, by plugging in we obtain:

P^{VdW}=\frac{0.08206\frac{atm*L}{mol*K}*295.45K}{0.533mol/L-0.0430L/mol} -\frac{2.300L^2*atm/mol^2}{(0.533L/mol)^2}\\\\P^{VdW}=49.44atm-8.09atm\\\\P^{VdW}=41.4atm

Thus, the pressure difference is:

\Delta P=45.5atm-41.4atm\\\\\Delta P=4.10atm

Best regards!

In a hydrogen atom, the electron and the proton are seperated by about 0.5 angstroms, 5.0×10−11 m. what is the acceleration of a
nadya68 [22]

The charge of proton and electron is equal in magnitude that is 1.6\times 10^{-19} C. The distance between electron and proton is 0.5 \AA or 5\times 10^{-11} m.

Force exerted on electron by proton is calculated as follows:

F= \left | \frac{kq_{e}q_{p}}{r^{2}} \right |

Here, k is Coulomb's constant, q_{p} is charge on proton,  q_{e} charge on electron and r is distance between them.

Putting the values,

F= \left | \frac{(8.99\times 10^{9}N m^{2}/C^{2})(1.6\times 10^{-19} C)(1.6\times 10^{-19} C)}{(5\times 10^{-11} m)^{2}} \right |=9.2\times 10^{-8} N

Now, according to second law of Newton,

F=m_{e}a

Here, m_{e} is mass of electron and a is acceleration.

Also, 1 N=1 kgm/s^{2}

Rearranging,

a=\frac{F}{m_{e}}=\frac{9.2\times 10^{-8} Kg m/s^{2}}{9.11\times 10^{-31} kg}=1.01\times 10^{23} m/s^{2}

Thus, the acceleration of an electron in this atom is 1.01\times 10^{23} m/s^{2}.
