Answer:
K = 1.69M
Explanation:
For the reaction:
2NH₃(g) ⇄ N₂(g) + 3H₂(g)
K is defined as:
k = [N₂] [H₂]³ / [NH₃]² <em>(1)</em>
Molarity in equilibrium for each specie is:
NH₃(g): 2.0mol - 2x = 1.0mol/1L = 1M → X = 0.5mol
N₂(g): X = 0.5mol/1L = 0.5M
H₂(g): 3X = 1.5mol/1L = 1.5M
Replacing:
k = [0.5] [1.5]³ / [1]²
<em>k = 1.69M</em>

The volume of water = 198 mL
Explanation:
Considering
Given that:
So,
<u>The volume of 2M stock solution added = 2 mL</u>
<u>The volume of water = 200 - 2 mL = 198 mL</u>

Explanation:
An element is a substance whose atoms have same number of protons which means all atoms in an element have same atomic number. Elements are simplest substances which cannot be broken down by physical changes or chemical reactions. Elements are classified by their names and symbols. Hope That Helps!
Answer:
The correct answer is 582.8.
Explanation:
To solve this problem, we must remember the rules for significant figures for addition. Recall that the answer should have the same number of decimal places as the term with the least number of decimal places that we are adding. In this case, we can see that out of our three terms, 98.3 has the least number of decimal places. This lets us know that our answer should be rounded to the tenths place.
With this in mind, we can compute the addition.
246.24 + 238.278 + 98.3
= 582.818 (unrounded value)
However, we stated that our answer should be rounded to the tenths place.
Therefore, our answer is 582.8.
Hope this helps!
