What molecule contains 12.17 g of carbon, 32.53 g of sulfur, and 72.19 g of chlorine

Answers

The molecule is thiophosgene or CSCl₂.

Explanation:

As the informations given, the molecule contains 12.17 grams of carbon, 32.53 g of sulfur, and 72.19 g of chlorine.

Molar mass of carbon =12.

Molar mass of sulphur =32.

Molar mass of chlorine =35.

So on an average estimation, one mole of the molecule contains one mole of carbon atoms, one mole of Sulphur atoms and two moles of chlorine atoms. Molar mass of an element is the average weight of one mole of atoms of that element which is made average according to the variations of percentage availability of isotopes of that element on earth.

So the estimated molecule is CSCl₂ or thiophosgene.

What evidence leads us to believe that energy levels in the hydrogen atom are quantities?

Answers

Answer:

Because only certain photons are emitted, we know that only certain energy changes are occurring. This means that the hydrogen atom must have certain discrete energy levels. Excited hydrogen atoms always emit photons with the same discrete colors (wavelengths). They never emit photons with energies between those shown. So we concluded, all hydrogen atoms have the same set of discrete energy levels.

What mineral is this? Irregularly shaped, white with nonmetallic luster, the hardness of 2.5, shows cubic cleavage and dissolves easily in water.

Answers

Answer:

The material we are talking about would be serpentine.

Explanation:

This material is available in two colours green or white and it has a hardness that amounts to 2.5. This material has a luster that is nonmetallic and more of waxy in nature.  

This feature becomes Satiny when Nature of is material is Fibrous. This material is used as an insulating material against electricity as well as heat. The property of this mineral is very close to asbestos and is used when prevention from heat and electricity is required.

Answer:

Halite

Explanation:

Halite is the mineral  which is called as Rock salt shows cubic cleavage

Halite forms clear transparent crystals with perfect cubic cleavage. Halite is Table salt, the salt is an array of small cubic fragments, the result of halite’s crystal structure and perfect cubic cleavage

Cubic cleavage can be produced by breaking the sample. Halite is one of the few common minerals that, when broken into small fragments, will readily dissolve in water.

Need help ASAP!!Which of the following sets of terms could be used in a description of the peripheral nervous system?

A) Motor neurons and sensory neurons

B) Brain and spinal cord

C) Motor neurons and brain

D) Sensory neurons and spinal cord

Answers

Answer:

A) Motor neurons and sensory neurons

Explanation:

We can answer the question by answering the following questions

What is the nervous system?

  • Nervous system is a s system in the body that helps in the coordination between all the body parts and the brain which is the control center.

How is the nervous system classified?

  • The nervous system is classified into central nervous system and peripheral nervous system.

What comprises of the central nervous system?

  • The central nervous system is made up the brain and the spinal cord.

What comprises of the peripheral nervous system?

  • The peripheral nervous system is comprised of all the parts of the nervous system outside the brain and the spinal cord.
  • It includes the sensory neurons and the motor neurons.
  • Motor neurons transmits impulses from the brain to the effector cells such as muscles and glands.
  • Sensory neurons, on the other hand, transmit nerve impulses from the sensory organs to the central nervous system.
