Answer:
<h2>Sodium Sulfide</h2>
Explanation:
Na2s means two sodium atoms and 1 sulfur atom. Sodium Sulfide is the answer. There isn't really a way to explain further.
<em>PLEASE MARK BRAINLIEST</em>
Answer:
It is the sum of internal energies of two or more substances
Explanation:
Missing question: What is the rate constant for the reaction?
<span>[RS2](mol L-1) Rate (mol/(L·s))
0.150 0.0394
0.250 0.109
0.350 0.214
0.500 0.438</span>
Chemical reaction: 3RS₂ → 3R + 6S.
Compare second and fourth experiment, when concentration is doubled, rate of concentration is increaced by four. So rate is:
rate = k·[RS₂]².
k = 0,438 ÷ (0,500)².
k = 1,75 L/mol·s.
Yes, but they are tubular organs and like all other organs are made up of tissues
