Chemistry
1 answer:
Kazeer [188]3 years ago
4 0

Answer:

Explanation:

If it interests you, you could check out Maxwell's demon. If he is not in operation (and he likely isn't), then the answer is D.

Heat always transfers from hot to cold -- at least at beginning levels of chemistry.

Given the unbalanced equation below, how many moles
Svet_ta [14]

Answer: 6 mol Li

Explanation:

The first step is to balance the equation.

2Li+Cl₂⇒2LiCl

We would need our conversions to find the amount of moles of Li needed to produces 6 mol LiCl.

6molLiCl*\frac{2molLi}{2molLiCl} =6molLi

A sample from solution a and solution b were each tested with blue colored glucose indicator solution before the solutions were
vova2212 [387]
With the given problem you gave here, I can't answer the question because I need more details. Luckily, I found a similar problem that's provided with a diagram and a table shown in the attached picture.

This test is called the Benedict's test which is used as test for presence of sugars. If the solution contains sugar, like glucose, the solution would turn from blue to red. If not, it would stay blue. <em>Therefore, the correct results would be that in row 3.</em>

A trial of this decomposition experiment, using different quantities of reactants than those listed in the question above produc
Paul [167]

Answer : The volume of O_2(g) produced at standard conditions of temperature and pressure is 0.2422 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of O_2 gas = (740-22.4) torr = 717.6 torr

P_2 = final pressure of O_2 gas at STP= 760 torr

V_1 = initial volume of O_2 gas = 280 mL

V_2 = final volume of O_2 gas at STP = ?

T_1 = initial temperature of O_2 gas = 25^oC=273+25=298K

T_2 = final temperature of O_2 gas = 0^oC=273+0=273K

Now put all the given values in the above equation, we get:

\frac{717.6torr\times 280mL}{298K}=\frac{760torr\times V_2}{273K}

V_2=242.2mL=0.2422L

Therefore, the volume of O_2(g) produced at standard conditions of temperature and pressure is 0.2422 L

If you did not use a watch glass to cover your stock iodine solution, and the concentration of iodine decreased over the course
anygoal [31]

Answer::

<u><em>Lower rate of reaction</em></u>

Explanation:

Lower concentration of reactant in an experiment is indicative of fewer ions or atoms present, which means a slower rate of reaction. In a titration reaction for instance, the end point would take longer to be substantiated, thereby increasing volume of titres. This is further backed up by collision theory which states that more particles in a system improves combinations of molecules.

This however may not be the case if the iodine in question is  catalyst, in which case the change in concentration has no effect whatsoever on the reaction rte.

I hope this explanation fits the brief.
