Answer:
It is associated witb heat absorbed or released
Explanation:
The word therm means Heat.
Hypochlorous acid is the answer
malory
The freezing point is the temperature at which things freeze.
Answer:
0.542M HCl
Explanation:
The reaction of H₂SO₄ with NaOH is:
H₂SO₄ + 2 NaOH → 2H₂O + Na₂SO₄
<em>Where 1 mole of acid reacts with 2 moles of NaOH</em>
Moles of H₂SO₄ are:
0.0500L × (0.361mol / L) = 0.01805 moles H₂SO₄
Thus, moles of NaOH that neutralize this acid are:
0.01805 moles H₂SO₄ × (2 mol NaOH / 1 mol H₂SO₄) = 0.0361 moles NaOH
And concentration is:
0.0361 moles NaOH / 0.0200L = <em>1.805M</em>
And, reaction of NaOH with HCl is:
NaOH + HCl → H₂O + NaCl
<em>Where 1 mole of NaOH reacts per mole of NaOH</em>
As you use 30.0mL = 0.0300L of NaOH to neutralize the HCl acid, moles of acid are:
0.0300L × (1.805mol / L) = 0.05415 moles NaOH = moles HCl
In 0.1000L:
0.05415 moles HCl / 0.1000L = <em>0.542M HCl</em>
A first-order reaction has a rate proportional to the concentration of one reactant. First-order rate constants have units of sec-1. In other words, a first-order reaction has a rate law in which the sum of the exponents is equal to 1.
