Answer:
Explanation:
It resembles a simple composition. Your instructor may not accept that answer. What is happening is the Fe is giving up 2 electrons so that it may embrace the C5H5.
That's usually what happens in a simple composition.
What makes me wonder is the C5H5. It has no charge and yet the Fe is shown as giving up 2 electrons. I'm guessing that either a halogen is introduced or something is to the left of C5H5 on the left side of the equation.
Anyway it is a composition of some kind.
The atoms didn't change we only added 2 different ones together. 2nd one is right
Answer:
pH = 2.25
Explanation:
pH is a measurement in chemistry defined as the -log [H₃O⁺]. Molarity [], is defined as the ratio between moles of solute (HCl) and the liters of solution
To solve this question we must find the molarity of the H₃O⁺ knowing: [HCl] = [H₃O⁺]
[HCl]:
0.0084moles / 1.500L
= 0.0056M = [HCl] = [H₃O⁺]
pH = -log [H₃O⁺] = -log [0.0056M]
<h3>pH = 2.25</h3>
The correct answer is B: dormancy. In response to unfavourable environmental conditions, such as over winter months, plants are able to enter a state of little to no growth, called dormancy. In addition to reducing or halting growth over dormancy periods, <span>deciduous</span> trees shed their leaves over winter, thereby avoiding water loss. Most trees also bud over spring and summer periods, when conditions are more favourable.
Answer: The outcome is his grass grew.
