Answer:

<h2>Electricity does not pass in non-electrolyte solution so bulb can not light.</h2>

Explanation:

Glucose is an organic compound that is made up of carbon, hydrogen, oxygen atoms. It is a type of polar molecule because it contains a hydroxyl group. Since the carbon-carbon bond and some other bond that are present in this compound is a covalent bond. When glucose is dissolved in water it does not dissociate into ions. So during the experiment bulb can not light due to the absence of ions. Such types of substances that do not dissociate into ions are knowns as nonelectrolytes such as glucose and some other substances.

almond37 [142]

Answer:

D. 0.3 M

Explanation:

                                              NH4SH (s)      <-->            NH3 (g) + H2S (g)

Initial concentration              0.085mol/0.25L             0                 0

Change in concentration     -0.2M                               +0.2 M        +0.2M

Equilibrium               0.035mol/0.25 L=0.14M             0.2M           0.2M

concentration

Change in concentration (NH4SH) = (0.085-0.035)mol/0.25L =0.2M

K = [NH3]*[H2S]/[NH4SH] = 0.2M*0.2M/0.14M ≈ 0.29 M ≈ 0.3M

Answer:

can't be done

Explanation:

protons and electrons always are the same number,and the neutrons are found by subtracting the atomic mass and protons/electrons soooooooo it can't have 15 protons, 18 electrons, and 18 neutrons.......i hope this helped if not please tell me.
