Some scientists believe that life on Earth may have originated near deep-ocean vents. Balance the following reactions, which are

among those taking place near such vents. Place coefficients directly in front of the compound, leaving no spaces.
CH3SH(l) + CO (g) → CH3CO(SCH3)(l) +H2S (g)
H2S(g) +CO(g) → CH3CO2H(g)+ S8(s)

Answer :

(1) The balanced chemical reaction will be,

2CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)

(2) The balanced chemical reaction will be,

8H_2S(g)+8CO(g)\rightarrow 4CH_3CO_2H(g)+S_8(s)

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

(1) The unbalanced chemical reaction is,

CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the CH_3SH and we get the balanced chemical equation.

The balanced chemical reaction will be,

2CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)

(2) The unbalanced chemical reaction is,

H_2S(g)+CO(g)\rightarrow CH_3CO_2H(g)+S_8(s)

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.

In order to balance the chemical equation, the coefficient '8' put before the H_2S\text{ and }CO and the coefficient '4' put before the CH_3CO_2H we get the balanced chemical equation.

The balanced chemical reaction will be,

8H_2S(g)+8CO(g)\rightarrow 4CH_3CO_2H(g)+S_8(s)

Answer:

2CH3SH(l) + CO (g) → CH3CO(SCH3)(l) +H2S (g)

8H2S(g) + 8CO(g) → 4CH3CO2H(g)+ S8(s)

Explanation:

Step 1: The unbalanced equation

CH3SH(l) + CO (g) → CH3CO(SCH3)(l) +H2S (g)

Step 2: Balancing the equation

CH3SH(l) + CO (g) → CH3CO(SCH3)(l) +H2S (g)

On the left side we have 1x S, on the right side we have 2x S (1x in CH3CO(SCH3) and 1x in H2S). To balance the amount of S, we have to multiply CH3SH on the left side by 2. Now the equation is balanced.

2CH3SH(l) + CO (g) → CH3CO(SCH3)(l) +H2S (g)

Step 1: The unbalanced equation

H2S(g) +CO(g) → CH3CO2H(g)+ S8(s)

Step 2: Balancing the equation

H2S(g) +CO(g) → CH3CO2H(g)+ S8(s)

On the left side we have 1x S and on the right side we have 8x S

To balance the amount of S on both sides we have to multply H2S on the left by 8.

8H2S(g) +CO(g) → CH3CO2H(g)+ S8(s)

On the left side we have 16x H and on the right side we have 4x H

To balance the amount of H on both sides we have to multply CH3CO2H on the right by 4.

8H2S(g) +CO(g) → 4CH3CO2H(g)+ S8(s)

On the left side we have 1x C and on the right side we have 8x C

To balance the amount of C on both sides we have to multply C0 on the left by 8. Now the equation is balanced.

8H2S(g) + 8CO(g) → 4CH3CO2H(g)+ S8(s)

What is the molecule that formed between B and F?
Alik [6]

Answer:

BF3

Explanation:

For this question, you need to use the number of valence electrons present in each element. Boron is in group 3/13 on the periodic table so you know it has 3 valence electrons while Fluorine is in group 7/17 so it has 7 valence electrons. These elements are both covalent so they will share electrons. All elements in the first three rows want to reach either have 8 valence electrons or zero valence electrons depending on whichever is easier. When B and F interact each Fluorine will only want to take one electron, but Boron wants to get rid of all 3 electrons, so it will bond with 3 Fluorine to get rid of all its valence electrons.

I hope this helps.

A particle has 5 protons, 6 neutrons, and 5 electrons. What is its net charge.
Trava [24]
It would have a zero charge because it is a neutral atom. The number of electrons which is a negative charge is equal to the number of protons which is positive, they will cancel each other out hence meaning it will become neutral

CO2+2H2O=H3O^++HCO3^-
bekas [8.4K]

<u>Answer:</u>

<em>Bronsted Lowry Theory</em>

<em>CO_2 is the acid </em>

<em>H_2 O is the base </em>

<em>H_3 O^+ is the conjugate acid and </em>

<em>HCO_3^- is the conjugate base</em>

<u>Explanation:</u>

Bronsted Lowry Theory:

An acid is a substance that can donate one or more protons

A base is a substance which can accept one or more protons

Hydrogen atom which is neutral (No Charge) contains 1 positive proton, 1 negative electron and 0 neutral neutron.  

Thus Hydrogen atom has no Charge and it is neutral.

When an hydrogen atom loses an electron, Hydrogen ion is formed, which will contain 1 positive proton and 0 negative electron and 0 neutral neutron.

Thus Hydrogen ion has a positive charge.  

Hydrogen ion is also called as a proton since it has only 1 proton in it.

Hydrogen ion in water that is,  

H^++H_2O\Rightarrow H_3O^+

H_3O^+ is called as Hydronium ion.

Acid loses H+ (proton) to form conjugate Base

Base gains H+ (proton) to form conjugate Acid

For example  

Let us consider the example given in the question

CO_2+2H_2 O>H_3 O^+   +HCO_3^- can be written as (removed 1 H_2 O from both the sides )

CO_2+H_2 O>H^++HCO_3^- or  

CO_2+H_2 O  > H_2 CO_3 reversing the equation  

H_2 CO_3+H_2 O>H_3 O^+  +HCO_3^-

H_2 CO_3 is the acid which donates H^+ to form HCO_3^-

H_2 O is the base which gains H^+ to form H_3 O^+

HCO_3^- is the conjugate base and H_3 O^+ is the conjugate acid

So

CO_2 is the acid

H_2 O is the base

H_3 O^+ is the conjugate acid and

HCO_3^- is the conjugate base
