How many resonance structures are there for [S2CO]2- ?

Chemistry
1 answer:
Irina-Kira [14]3 years ago
5 0

Answer:

Three

Explanation:

1. Draw a Lewis structure

  • Put the least electronegative atom (C) in the centre
  • Attach the O and two S atoms to the C.
  • Add enough electrons to give each atom an octet.

2. Draw the resonance structures

You should get one of the structures below.

It has a double bond and two single bonds.

The resonance structures will have the double bond in each of the other two positions.

How do you boil water less than 100​
natita [175]

Answer: When pressure cooker is used steam is trapped in the pot and it increases the pressure above the water. this causes the water to boil at a temperature more than 100 C. when you pull back on the plunger, the pressure in the syringe is reduced and the liquid boils at a lower temperature

Explain your observations in term of how tempurature affects paritcle motion and how liquid changes to a solid
Rus_ich [418]

Answer:

See explanation

Explanation:

Temperature is defined as a measure of the average kinetic energy of the molecules of a body.

When a substance is heated, the kinetic energy of its molecules increases as the temperature increases; hence the particles of the substance moves faster with increasing temperature.

When heat is withdrawn from a liquid, the temperature decreases and the average kinetic energy of the molecules decreases. The molecules become less energetic hence the liquid changes into solid

Carbon-14 has a half-life of 5,730 years. How long will it take for 112. 5 g of a 120. 0-g sample to decay radioactively? 5,730
vichka [17]

The time taken by Carbon-14 to decay radioactively from 120g to 112.5g is 22,920 years.

<h3>How do we calculate the total time of decay?</h3>

Time required for the whole radioactive decay of any substance will be calculated by using the below link:

T = (n)(t), where

  • t = half life time = 5730 years
  • n = number of half life required for the decay

Initial mass of Carbon-14 = 120g

Final mass of Carbon-14 = 112.5g

Left mass = 120 - 112 = 7.5g

Number of required half life for this will be:

  • 1: 120 → 60
  • 2: 60 → 30
  • 3: 30 → 15
  • 4: 15 → 7.5

4 half lives are required, now on putting values we get

T = (4)(5730) = 22,920 years

Hence required time for the decay is 22,920 years.
