I think it's Sodium Sulfide, because Na2S contains one Sodium and two Sulfur. Plus Sulfide<span> is used to describe any of three types of chemical compounds that contain sulfur.</span>
Answer:
(B) II only
Explanation:
In an equilibrium reaction, a keq > 1 means that the reaction is thermodynamically favored. That means the reaction will occurs doing the <em>II affirmation</em> <em>TRUE</em>. But the thermodynamic information doesn't make reference to the rate of the reaction doing <em>I affirmation</em> <em>FALSE</em>. Also, the Keq have relationship with ΔG parameter but ΔH parameter (exothermic or endothermic reaction) is independent of ΔG doing<em> III affirmation</em> <em>FALSE</em>. Thus, right answer is:
<em>(B) II only

Explanation:
The <em>blue whale </em>is the largest animal on Earth. The length of a blue whale is about 25 m, although is is said the largest confirmed measure is 29.9m.
The<em> tiny frogs </em>measure about 10mm.
You can estimate the number of tiny frogs that have the same <em>length</em> as a blue whale dividing the approximate average length of a blue whale by the approximate average length of the tiny frogs.
First convert 25m to mm:
- 25m × 1,000mm/m = 25,000 mm
Now, divide:
Hence, about 2,500 <em>tiny frogs sitting next to each other would measure the same length as a blue whale</em>.
