Answer:

The answer is

21.5 L

.

So, start with the balanced chemical equation for the decomposition of hydrochloric acid

2

HCl

→

H

2

+

Cl

2

Notice that you have a

2:1

mole ratio between

HCl

and

Cl

2

, which means that every 2 moles of the former will produce 1 mole of the latter. The number of moles of

HCl

you have is.

Explanation:

I don't know if that is but I try my best just correct me if I'm wrong thank you!!

* Who can help with this lol *
Viktor [21]

Answer: subduction and sea floor spreading

Explanation:

He knew that the continents today were once joined together by fossil records of plants and animals that were found to be on continents far removed from each other. He knew this also by corresponding land forms that matches up as well. What he couldn’t prove is how the land masses would have moved so far away from each other. Subduction and sea floor spreading move the tectonic plates that the continents sit on. That’s what he was missing.

In the lewis structure of ch3oh, how many lone pairs of electrons are there? in the lewis structure of ch3oh, how many lone pair
Lunna [17]
The structure of Methanol (CH₃OH) is shown below. This structure contains 2 lone pair of electrons on oxygen (highlighted red). Electronic configuration of oxygen is,

                        Oxygen  =  8  =  1s², 2s², 2px², 2py¹, 2pz¹

There are six electrons in valence shell of oxygen, among these six electrons two electrons are unpaired and involved in forming covalent bond with hydrogen and carbon, while remaining 4 electrons in pair (i.e. 2s², 2px²) exists as lone pairs.

Given the molar specific heat cv of a gas at constant volume, you can determine the number of degrees of freedom s that are ener
Ksju [112]
The molar specific heat Cv = R s / 2
70.6 J/mol.K = (8.314 J/mol.K) * s / 2
So the number of degrees of freedom are:
s = 16.98 = 17
