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)

If a sample of sodium chloride with a mass of
alex41 [277]
Original molarity was 1.7 moles of NaCl

Final molarity was 0.36 moles of NaCl

Given Information:

Original (concentrated) solution: 25 g NaCl in a 250 mL solution, solve for molarity

Final (diluted) solution: More water is added to make the new total volume 1.2 liters, solve for the new molarity

1. Solve for the molarity of the original (concentrated) solution.

Molarity (M) = moles of solute (mol) / liters of solution (L)

Convert the given information to the appropriate units before plugging in and solving for molarity.

Molarity (M) = 0.43 mol NaCl solute / 0.250 L solution = 1.7 M NaCl (original solution)

2. Solve for the molarity of the final (diluted) solution.

Remember that the amount of solute remains constant in a dilution problem; it is just the total volume of the solution that changes due to the addition of solvent.

Molarity (M) = 0.43 mol NaCl solute / 1.2 L solution

Molarity (M) of the final solution = 0.36 M NaCl

Are plant cells affected when water is scarce
boyakko [2]
<span>Water is vital to the existence of plant life. Not only do plants use it to keep their cells from drying out, but they need water to move nutrients and raw materials throughout their systems to areas where photosynthesis and seed production take place. When water stress occurs, whether caused by drought or root impairment, many invisible processes are affected.</span>
