Alpha-emitting substances, such as radon gas, can be a serious health hazard only if \boxed{{\text{their radiation strikes the skin}}}.

Further Explanation:

When an unstable nucleus tends to stabilize itself by the emission of radiations such as alpha particles, beta particles and gamma rays, the process is called radioactivity. Such substances are known as radioactive substances. This process is also called radioactive disintegration or decay. Uranium, carbon-14, iridium-192 and cobalt-60 are some examples of radioactive substances.

Radon is a radioactive natural gas that is produced from the radioactive disintegration of uranium. It is the second major cause of lung cancer after cigarette smoking. The radioactive particles present in radon gas are released by it when radon is inhaled or ingested in the body. When the skin comes in contact with these radiations, cells and tissues are damaged. It leads to lung cancer. The risk of lung cancer depends on the extent of radon inhalation.

sergeinik [125]
<span>The type of map that shows the type and age of rocks in an area is called a Geologic Map. A geologic map is a special-purpose map that represents the distribution of diverse types of rocks, as well as locations of different geologic structures such as faults and folds. This map is the main source of information for various aspects of land-use planning, especially in the placement of transportation systems and buildings. Although they are typically depicted as two-dimensional, they can also be illustrated in its third or fourth dimension depending on the type of information needed to be taken. </span>

A 7.06% aqueous solution of sodium bicarbonate has a density of 1.19g/mL at 25°C what is the molarity and molality of the soluti
lilavasa [31]

<em>c</em> = 1.14 mol/L; <em>b</em> = 1.03 mol/kg

<em>Molar concentration </em>

Assume you have 1 L solution.

Mass of solution = 1000 mL solution × (1.19 g solution/1 mL solution)

= 1190 g solution

Mass of NaHCO3 = 1190 g solution × (7.06 g NaHCO3/100 g solution)

= 84.01 g NaHCO3

Moles NaHCO3 = 84.01 g NaHCO3 × (1 mol NaHCO3/74.01 g NaHCO3)

= 1.14 mol NaHCO3

<em>c</em> = 1.14 mol/1 L = 1.14 mol/L

<em>Molal concentration</em>

Mass of water = 1190 g – 84.01 g = 1106 g = 1.106 kg

<em>b</em> = 1.14 mol/1.106 kg = 1.03 mol/kg
