The pressure in the flask is 3.4 atm.
<em>pV</em> = <em>nRT
</em>
<em>T</em> = (20 + 273.15) K = 293.15 K
<em>p</em> = (<em>nRT</em>)/<em>V</em> = (1.4 mol × 0.082 06 L·atm·K⁻¹mol⁻¹ × 293.15 K)/10 L = 3.4 atm

<u>Explanation:</u>
- A mammogram is an X-ray of the breast. Mammograms are commonly used to screen for breast cancer.
- Radio-tracking technology assists in determining exactly where an animal is located at any instant in time and frequently what that animal is performing! Utilizing the data collected from tracking devices, scientists can conclude the day-to-day activities of an animal, the size of an animal's place range, what other animals share an animal's range and the types of habitats an animal practices.
- Gamma-rays are the common energetic form of light and are generated by the most heated regions of the universe. Gamma rays are provided by such extreme events as supernova explosions or the elimination of atoms and by less exciting events, such as the breakdown of radioactive material in space.
I think the answer for #3 is A not 100% sure but hope I can help!
