A common mineral of barium is barytes, or barium sulfate (BaSO4). Because elements in the same peri- odic group have similar che

mical properties, we might expect to find some radium sulfate (RaSO4) mixed with barytes since radium is the last member of Group 2A. However, the only source of radium com- pounds in nature is in uranium minerals. Why

<h3><u>Answer;</u></h3>

Hydroelectric power

<h3><u>Explanation</u>;</h3>
  • Hydroelectric power is produced when a turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
  • Hydroelectric power plants uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.

Hydrogen chloride gas is shipped in a container under 5,100 mm Hg of pressure that occupies 20.1 liters at 29°C. How many liters
Agata [3.3K]

The gas will occupy 120 L at STP.

We can use the <em>Combined Gas Laws</em> .

In 1982, chemists redefined <em>STP</em> as <em>1 bar</em> and 0 °C (273.15 K).

<em>p</em>_1 = 5100 mmHg × (1 atm/760 mmHg) × (1.013 bar/1 atm) = 6.798 bar

<em>T</em>_1 = (29 + 273.15) K = 302.15 K

<em>p</em>_1<em>V</em>_1/<em>T</em>_1 = <em>p</em>_2<em>V</em>_2/<em>T</em>_2

<em>V</em>_2 = <em>V</em>_1 × <em>p</em>_1/<em>p</em>_2 × <em>T</em>_2/<em>T</em>_1

= 20.1 L × (6.798 bar/1 bar) × (273.15 K/302.15 K) = 120 L
