Answer:

The big freeze or heat death
But the expansion would stretch everything out until everything is evenly spread through the universe. When that happens, objects can gain or lose energy. The gas clouds that form stars would dissipate, black holes would evaporate and eventually even light particles would fizzle out.

Which of these compounds has the correct chemical formula? 1. ba3po4 2. (nh4)2so4 3. mg2oh 4. lif2 5. caoh?
sergiy2304 [10]
Ba3PO4 is not neutral, it is positive.  (NH4)2SO4 is neutral, the charges cancel.
Mg2OH is not neutral, it is positive.  LiF2 is not neutral, it is negative.  CaOH is not neutral, it is positive.  The answer is (NH4)2SO4, correct ions will have a neutral charge.

A 2.5 L container holds a sample of hydrogen gas at 291 K and 180 kPa.
netineya [11]

Answer:

The new temperature will be 565.83 K.

Explanation:

Gay Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant. This law says that the pressure of the gas is directly proportional to its temperature. This means that if the temperature increases, the pressure will increase; or if the temperature decreases, the pressure will decrease.

In other words, Gay-Lussac's law states that when a gas undergoes a constant volume transformation, the ratio of the pressure exerted by the gas temperature remains constant:

\frac{P}{T} =k

When an ideal gas goes from a state 1 to a state 2, it is true:

\frac{P1}{T1} =\frac{P2}{T2}

In this case:

  • P1= 180 kPa
  • T1= 291 K
  • P2= 350 kPa
  • T2= ?

Replacing:

\frac{180 kPa}{291 K} =\frac{350 kPa}{T2}

Solving:

T2=350 kPa*\frac{291 K}{180 kPa}

T2= 565.83 K

<u><em>The new temperature will be 565.83 K.</em></u>
