In Thomson's experiment, he showed that an electrical current can be made to flow from a positive site to a negative site.
Answer:1:1
There is a 1:1 molar ratio between magnesium and magnesium chloride. Magnesium has a molar mass of 24.31g/mol.
Explanation:
If you begin with 25.0 g of magnesium, how many moles of magnesium oxide will ... g C9H8O4. Now calculate percent yield. % yield = actual theoretical. × 100 =.

Answer:
Half-life at 629K = 252.4min
Explanation:
Using Arrhenius equation:
And as Half-life in a first order reaction is:
We can convert the half-life of 58.0min to know K₁ adn replacing in Arrhenius equation find half-life at 629K:
K = 0.01195min⁻¹ = K₁
K₂ = 2.75x10⁻³ min⁻¹
And, replacing again in Half-life expression:
<h3>Half-life at 629K = 252.4min</h3>
