Is the following relation a function?​

Chemistry
1 answer:
____ [38]3 years ago
8 0

Answer:

Explanation:

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

Hope That Helps!!!

Select the single best answer. Which mechanism properly shows the movement of electrons in the reaction? 2xsafari
sweet [91]

Answer:

D

Explanation:

We must study the reaction pictured in the question closely before we begin to attempt to answer the question.

Now, the reaction is a free radical reaction. This implies that only one electron is transferred. The transfer of one electron is shown using a half arrow rather than a full arrow. The both species are radicals (odd electron species) and contribute one electron each.

Hence we must show electron movements in both species using a half arrow.

Use bond energies to determine δhrxn for the reaction between ethane and chlorine. ch3ch3(g)+cl2(g)→ch3ch2cl(g)+hcl(g)
STALIN [3.7K]
For this reaction to proceed, the following bond breaking should occur: 

*one C-H bond
* one Cl-Cl bond

After, the following bond formations should occur:
*one C-Cl bond
*one H-Cl bond

Now, add the bond energies for the respective bond energies which can be found in the attached picture. For bond formations, energy is negative. For bond breaking, energy is positive.

ΔHrxn = (1)(413) + (1)(242) + 1(-328) + 1(-431) = <em>-104 kJ</em>

Which of these solutions is the most basic?
dalvyx [7]
<h2>Question↷</h2>

Which of these solutions is the most basic?

[OH-] = 4.3 x 10-9 M

[OH-] = 2.8 x 10-11 M

[OH-] = 6.7 x 10-10 M

[OH-] = 1.0 x 10-5 M

<h2>Answer↷</h2>

  • <u>[OH-] = 1.0 x 10-5 M</u> ✓

<h2>Solution↷</h2>

[OH-] = 4.3 x 10-9 M

  • [OH-] = 4.3 x 10^-9 M
  • pOH = - log [OH^1-]
  • pOH = - log [4.3 x 10^-9]
  • pOH = 8.36
  • pH = 14- 8.36
  • pH = 5.64

_______________________________________

[OH-] = 2.8 x 10-11 M

  • [OH-] = 2.8 x 10^-11 M
  • pOH = - log [OH^1-]
  • pOH = - log [2.8 x 10^-11 ]
  • pOH = 10.55
  • pH = 14-10.55
  • pH = 3.45

_______________________________________

[OH-] = 6.7 x 10-10 M

  • [OH-] = 6.7 x 10^-10 M
  • pOH = - log [OH^1-]
  • pOH = - log [6.7 x 10^-10]
  • pOH = 9.17
  • pH = 14-9.17
  • pH = 4.83

_______________________________________

[OH-] = 1.0 x 10-5 M

  • [OH-] = 1.0 x 10-5 M
  • pOH = - log [OH^1-]
  • pOH = - log [1.0 x 10^-5 ]
  • pOH = 5
  • pH = 14-5
  • pH = 9

_______________________________________

we know that , the solution with <u>pH > 7</u> is termed as basic and more the pH ,more the basicity, hence ,the solution with the highest pH would be the strongest base out of these all which is

<u>[OH-] = 1.0 x 10-5 M</u> with pH = 9
