Answer:
the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers.
Explanation:
G o o g l e
Answer:
60 g
Explanation:
The formula relating mass (<em>m</em>), heat (<em>q</em>), and temperature change (Δ<em>T</em>) is
<em>q = mC</em>Δ<em>T</em> Divide both sides by <em>C</em>Δ<em>T</em> and switch
<em>m</em> = <em>q</em>/(<em>C</em>Δ<em>T</em>)
<em>q</em> = 1260 J
<em>C</em> = the specific heat capacity of water = 4.184 J·K⁻¹g⁻¹
Δ<em>T</em> = <em>T</em>₂ - <em>T</em>₁ = 313 K – 308 K = 5 K
<em>m</em> = 1260/(4.184 × 5)
<em>m</em> = 1260/21
<em>m</em> = 60 g
<span> that the reaction is preferably called an elimination, rather than a dehydration, although I personally like the term dehydration because it emphasizes the strong dehydrating power of H2SO4 that is unfotunately forgotten too often by undergraduates. I like to think of it as H2SO4 has such a strong affinity for water that it literally pulls water molecules from organics.</span>
