3 0
During diffusion substances move from the denser medium (meaning where there is more of the substance) to less dense medium (meaning where there is less of the substance).

A sample of gas in a closed container at a temperature of 76°c and a pressure of 5.0 atm is heated to 399°c. What pressure does
NikAS [45]

<u>Answer:</u> The pressure that the gas exert at high temperature is 9.63 atm

<u>Explanation:</u>

To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1\text{ and }T_1 are the initial pressure and temperature of the gas.

P_2\text{ and }T_2 are the final pressure and temperature of the gas.

We are given:

P_1=5.0atm\\T_1=76^oC=[76+273]K=349K\\P_2=?\\T_2=399^oC=[273+399]K=672K

Putting values in above equation, we get:

\frac{5.0atm}{349K}=\frac{P_2}{672K}\\\\P_2=9.63atm

Hence, the pressure that the gas exert at high temperature is 9.63 atm

Ordena de mayor a menor según sus radios iónicos a los siguientes iones:
I am Lyosha [343]

Answer:

The correct order of the elements, taking into account their ionic radius from highest to lowest, is:

<em>a) Cl⁻¹ > F⁻¹ > Na⁺¹ > Mg⁺²</em>

<em>b) S⁻² > O⁻² > Li⁺¹ > Be⁺²</em>

<em>c) S⁻² > Cl⁻¹ > K⁺¹ > Na⁺¹</em>

Explanation:

In ions the ionic radius is determined by the amount of electrons an element gains or loses to become an ion.  The more negative an ion is, the greater its ionic radius.

As a rule, anions (negative charge) have a larger ionic radius than cations (positive charge), because the loss of electrons means a contraction of the ionic radius, while the gain of electrons means a greater radius.

To determine which ionic radius is greater in anions or cations with the same charge, it must be considered that in the periodic table the ionic radius increases from top to bottom and from right to left.
