Answer:
A
Explanation:
4 grams reactant U+3 grams reactant V to 7 grams product W
<span>0.333 ounce * 0.75 * 28.35 grams/ounce = 7.080 grams gold
7.080 grams Au / 196.967g/mol Au = 0.0359 mol Au
0.0359 mol Au * (6.023 * 10^23) atoms/mol = 2.24 * 10^22 Atoms Au</span>
The magnitude of k at 65.0∘C : 1912.7 /s
<h3>Further explanation</h3>
Given
k at 25 °C = 1.35 x 10² /s k1
T₁=25 + 273 = 298 K
T₂=65 + 273 = 338 K
Required
the magnitude of k at 65.0∘C
