Answer:

4.530 X 10^23 MOLECULES OF CO2

Explanation:

Calculate the number of carbon dioxide (CO2) molecules produced in the

reaction if 0.7525 moles of oxygen gas (O2) are consumed

C + O2-----------CO2

1 MOLE OF 02 produces 1 mole of CO2

0.7525 moles O2 produce 0.7525 moles

1 mole is 6.02 X 10^23

0.7525 moles is 0.7525 X 6.02 X 10^23 -

4.530 X 10^23 MOLECULES OF CO2

How to find efficiency of a pulley system

Digiron [165]

Multiply the weight of the object by the distance it traveled to find the amount of work output. For the example: 10 lbs. x 1 foot = 10 foot-pounds. Find the work efficiency by dividing the work output by the work input and multiplying by 100.

Use Lewis theory to draw the structure of the compound containing 1 carbon and 4 chlorine atoms. What would you find surrounding

Nikolay [14]

Answer : The correct option is, (B) no double bonds.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

As we are given that the structure of the compound containing 1 carbon and 4 chlorine atoms.

Thus, the molecule is, $CCl_4$

As we know that carbon has '4' valence electrons and chlorine has '7' valence electrons.

Therefore, the total number of valence electrons in $CCl_4$ = 4 + 4(7) = 32

According to Lewis-dot structure, there are 8 number of bonding electrons and 24 number of non-bonding electrons.

From the Lewis-dot structure we conclude that there are 4 single bonds are surrounding the central atom of this ion there is no double or triple bonds are present.

Hence, the correct option is, (B) no double bonds.

Treatment of p-hydroxybenzoic acid with aqueous bromine leads to the evolution of carbon dioxide and the formation of 2,4,6-trib

Nastasia [14]

Answer:

Aromatization leads to evolution of carbon dioxide

Explanation:

In p-hydroxybenzoic acid, -OH and -COOH groups remain in para position.

The directing effect of -OH and -COOH group act synergistically to react with three equivalent of bromine.

In para position of -OH group, -COOH remains attached along with a Br atom in a same carbon atom. During aromatization of benzene group, this -COOH group decomposes to give carbon dioxide.

Reaction scheme has been shown below.
