Why don't noble gases normally form chemical bonds?

Noble gases already have a full outer valence shell...whcih can only hold a maximum of 8 electrons. since the outer shell is filled, it doesn't have any empty electron spaces to form chemical bonds with other elements

The veterinarian prescribes the NSAID carprofen for a 50-pound dog with arthritis at a dose of 4.4 mg/kg and would like this dos
alina1380 [7]

Answer:

The dog should be given half of 100 mg tablet in the morning and another half of 100 mg tablet in an evening.

Explanation:

Weight of the dog = 50 pounds = 22.68 kg

1 kg = 2.205 pounds

Amount of daily dose prescribed by doctor = 4.4 mg/kg

Total mount of dose = 4.4 mg/kg × 22.68 kg = 99.79 mg

99.79 mg ≈ 100 mg

49.89 mg ≈ 50 mg

So, according to doctor prescription dog should be given half 100 mg tablet in the morning and another half of 100 mg tablet in an evening.

A container holds 6. 4 moles of gas. Hydrogen gas makes up 25% of the total moles in the container. If the total pressure is 1.
ipn [44]

In a mixture of gases, the total pressure is equivalent to the aggregate of all the partial pressures of the single element of the gas.

It can be written as \rm P _{total} = P₁ + P₂ +  P₃ and so on.

The partial pressure will be:

Option A. 0. 31 atm

Pressure can be estimated by:

<u>PV = nRT</u>

\rm P_{total} = \dfrac{n _{total }RT}{ V}

\rm P_{total} = \dfrac{n _{H_{2}} + n _{\rm other \;gases}}{ V}

Where,

\rm nH_{2} = 25\% \times n_{Total}

And,

\begin{aligned}\rm P_{H_{2}} &= 25\% \times \rm P_{Total}\\\\& = 25\% \times 1.24 \;\rm atm\\\\& = 1.24 \rm \;atm \times 25 \end{aligned}

Solving finally we get,

\rm  P_{H_{2}} = 0.31 \;\rm atm

Therefore, 0.31 atm is the partial pressure of the hydrogen gas.
