Answer:

1) The amount is less than one mole, 2) The jar is not completely filled, 3) We have 0.166 moles of sulfur.

Explanation:

We proceed to respond each question below:

1) <em>Is this amount more or less than one mole?</em>

According to the Avogadro's Number, one mole of an element contains about 6.022\times 10^{23} atoms. Given that we have 1.000\times 10^{23} atoms, then we conclude that this amount is less than one mole.

2) <em>Place the jar underneath the counter. Was the jar completely filled?</em>

Let suppose that the jar can contain up to a mole of sulfur. Then, we conclude that jar is not completely filled.

3) <em>How many moles do you have?</em>

The amount of moles is determined by dividing the current amount of atoms by Avogadro's Number:

x = \frac{1.000\times 10^{23}\,atoms}{6.022\times 10^{23}\,\frac{atoms}{mole} }

x = \frac{500}{3011}\,mole

We have 0.166 moles of sulfur.

A certain first order reaction has a half-life of 54. 3 s. How long will it take (in s) for the reactant concentration to decrea
Maksim231197 [3]

Answer:

82.4 s

Explanation:

Find the NUMBEr of half lives...then multiply by 54.3

2.27 = 6.5 (1/2)^n

log (2.27/6.5) / log (1/2) = n = 1.52 half lives

1.52 * 54.3 = 82.4 s

: Citric acid, H3C6H5O7, is a triprotic acid. Consider a buffer system comprising H2C6H5O7 - and HC6H5O7 2- ions. What is the ne
olchik [2.2K]

Answer:

The Net reaction is    

  1.    H_3C_6H_5O_7 + 0H^- ----> H_2C_6H_5O_7^- +H_2O \ \ \ \ \ \ \ Main \ Reaction
  2.    H_2C_6H_5O_7^ - + OH^- ----> H_C_6H_5O_7^{ 2-} + H_2O \ \ \ \ Add \ NaOH
  3.    HC_6H_5O_7 ^{2-} + OH^- ---> C_6H_5O_7^{3-} +H_2O \ \ \ \ \ Add \ NaOH  

Explanation:

From the Question we are told that the buffers are

                H_2C_6H_5O_7^ - and  HC_6H_5O_7 ^{ 2-}

When NaOH is added the Net ionic reaction would be

  1.    H_3C_6H_5O_7 + 0H^- ----> H_2C_6H_5O_7^- +H_2O \ \ \ \ \ \ \ Main \ Reaction
  2.    H_2C_6H_5O_7^ - + OH^- ----> H_C_6H_5O_7^{ 2-} + H_2O \ \ \ \ Add \ NaOH
  3.    HC_6H_5O_7 ^{2-} + OH^- ---> C_6H_5O_7^{3-} +H_2O \ \ \ \ \ Add \ NaOH

The direction of electrical force is based on the fact that like charges will___each other.
NeTakaya

Answer:

repel

Explanation:

When it comes to electrical forces, "opposites charges attract" while "like charges repel."

There are primarily two types of charges: positive charge and negative charge. The forces they exert upon each other will depend on their charges. The<u> positive charge has an </u><em><u>attractive force</u></em><u> to a negative charge.</u> On the contrary,<u> it has a</u><em><u> repulsive force</u></em><u> to the same positive charge</u>. Thus, it will repel each other.

So this means that <em>opposite charges will draw closer together</em> while<em> like charges will move apart from each other.</em>
