Answer:
A
Explanation:
idk but i do know its right
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
The Moon<span> moves </span>around<span> the </span>Earth in<span> an </span>approximately<span> circular </span>orbit<span>, going once </span>around<span> </span>in approximately<span> 27.3 </span><span>days. </span>The moon orbits quite fast: it moves about 0.5 degrees<span> per hour in the sky. So, its average movement in a day is around 13 degrees. 5 days x 13 degrees is approximately 65 degrees. </span>
