The size of the gas particles compared to the overall volume of the gas is 22.4 L
jeka57 [31]
Well. Yeah. Basically.

1 mole of any gas is 22.4 L. 

Not really sure if that answers your question but that's what i know. 
Anyway if we are talking about the size then usually gases are filled with empty space.

A cell has the reaction Co2+ (aq) + Cd(s) -------> Cd2+ (aq) + Co(s) E0cell = +0.120 V What is Ecell when [Co2+] = 0.00100 M
musickatia [10]

Answer:

USe this Nernst equation and find your required answer

Explanation:

E = E0 -  [0.0592 /n ] log [Cd+2]/[Co2+]

Wher Eo is  +0.120 V

[Cd+2] =0.1

[Co2+] = 0.001

n is number of electons transfered int he process and in your case it is = 2

E= 0.120- 0.0296 * log 100

  = ........  V

<u>Answer:</u> The correct option is 1 mole of acetic acid was required for 2 moles of sodium bicarbonate

<u>Explanation:</u>

We are given:

Average number of drops of sodium bicarbonate = 142

The chemical equation for the reaction of sodium bicarbonate and acetic acid in vinegar follows:

NaHCO_3+CH_3COOH\rightarrow CH_3COONa+H_2CO_3

From the stoichiometry of the reaction:

1 mole of sodium carbonate reacts with 1 mole of acetic acid in vinegar.

Hence, the correct option is 1 mole of acetic acid was required for 2 moles of sodium bicarbonate

2HgO—&gt;2Hg+O2. I start with 46.8 g HgO. What is my theoretical yield of O2?
jok3333 [9.3K]

Answer:

Theoretical yield = 3.52 g

Percent yield =65.34%

Explanation:

Given data:

Mass of HgO = 46.8 g

Theoretical yield of O₂ = ?

Percent yield of O₂ = ?

Actual yield of O₂ =  2.30 g

Solution:

Chemical equation:

2HgO  →   2Hg + O₂

Number of moles of HgO = mass/ molar mass

Number of moles of HgO = 46.8 g / 216.6 g/mol

Number of moles of HgO = 0.22 mol

Now we will compare the moles of HgO with oxygen.

                         HgO             :             O₂

                             2               :               1

                            0.22           :          1/2×0.22 = 0.11 mol

Theoretical yield:

Mass of oxygen = number of moles × molar mass

Mass of oxygen =  0.11 mol × 32 g/mol

Mass of oxygen = 3.52 g

Percent yield :

Percent yield = actual yield / theoretical yield × 100

Percent yield = 2.30 g/ 3.52 g × 100

Percent yield =65.34%

Why is gas production not recognized as nitrate reduction?
Snezhnost [94]
The gas production not recognized as nitrate reduction is because <span>organisms that can ferment also produce gas. Therefore even if gas is produced on the tube, you can't tell if it's by fermentation or by nitrate reduction. I hope the answer helps. </span>
