Answer:
<h2>
<em>Urea</em></h2>
Explanation:
<h3>
Urea = CH₄N₂O (Carbamide)</h3>
<em>It</em><em> </em><em>was</em><em> </em><em>the</em><em> </em><em>first</em><em> </em><em>organic</em><em> </em><em>compound</em><em> </em><em>to</em><em> </em><em>be</em><em> </em><em>synthesized</em><em> </em><em>in</em><em> </em><em>laboratory</em><em> </em><em>from</em><em> </em><em>the</em><em> </em><em>inorganic</em><em> </em><em>chemicals</em><em>.</em>
Polar bond is formed by 2 non-metal atoms which have a significant difference in electronegativity.
Answer: Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
It's impossible for it to be summer and winter in the same hemisphere because the southern and northern hemispheres have their seasons inverted. For example; when it is summer in the US it is winter in Australia.
Hope this helps :)
Answer:
<u><em>I HOPE IT WILL BE YOUR ANSWER:</em></u>
Explanation:
As given
60 min = 50 gm (1)
then we know half-life mean half amount decay time
so we can write as the half of 200 is 100 gm hence
T 1/2 = 100 (2)
solving these two equation by cross multiplication we will get
T 1/2 = 120 min
