Answer 1
Answer:

Answer: Compounds having the same empirical formula CH_2O are:

C_2H_4O_2,C_3H_6O_3,C_5H_(10)O_5,C_6H_(12)O_6

Explanation:

Empirical formula tells us about the proportion of the elements present in the compound but it do not tells us about the actual numbers of atoms of the elements present in the compound.

In given empirical formula CH_2O that is proportion of  C:H:O = 1:2:1

In C_2H_4O_2 the proportion of C:H:O =2:4:2= 1:2:1

In C_3H_6O_3 the proportion of C:H:O =3:6:3= 1:2:1

In CH_2O_2 the proportion of C:H:O =1:2:2= 1:2:2

In C_5H_(10)O_5 the proportion of C:H:O =5:10:5= 1:2:1

In C_6H_(12)O_6 the proportion of C:H:O =6:12:6= 1:2:1

Compounds having the given empirical formula CH_2O are:

C_2H_4O_2,C_3H_6O_3,C_5H_(10)O_5,C_6H_(12)O_6

Answer 2
Answer:

The chemical compounds that have the empirical formulaCH_2O are:

A.C2H4O2

B.C3H6O3

D.C5H10O5

E.C6H12O6

An empirical formula can be defined as a formula that gives the smallest and simplest whole number ratio of the atoms of a chemical element found in a chemical compound.

The simplest whole number ratio of the atoms of  CH_2O is:

CH_2O = 1:2:1

  • 1 atom of carbon.
  • 2 atoms of hydrogen molecule.
  • 1 atom of oxygen.

For C_2H_4O_2:

C_2H_4O_2 = 2:4:2 = 1:2:1

For C_3H_6O_3:

C_3H_6O_3 = 3:6:3 = 1:2:1.

For CH_2O_2:

CH_2O_2 = 1:2:2 = 1:1:1  (Incorrect)

For C_5H_(10)O_5:

C_5H_(10)O_5 = 5:10:5 = 1:2:1

For C_6H_(12)O_6:

C_6H_(12)O_6 = 6:12:6 = 1:2:1

Note:

  • C is the chemical symbol of carbon.
  • H is the chemical symbol of hydrogen.
  • O is the chemical symbol of oxygen.

Highlight the basic points in Lewis and Langmuir theory of electrovalency

Answers

The correct answer for the question that is being presented above is this one: "Electrovalency is characterized with the transferring of one or more electrons from one atom to another together with the formation of ions and as well as the number of positive and negative charges. 

The Lewis and Langmuir theory of electrovalency (and as well as Kossel's) is dealing with Ionic bonds. 

Lewis: electron-pair sharing, octet rule, Lewis Symbols or StructureLangmuir: introduced term "covalent" bond, and popularized Lewis's ideas

The Lewis-Langmuir electron-pair or covalent bond is referred as the homopolar bond, where the complete transfer of electrons give rise to ionic, or electrovalent bond (1) through attraction of opposite charges.

When light waves hit ice, most of them bounce off and radiate back into space. Because of this, ice is best described as which kind of surface? reflective absorbent dense rough

Answers

The bouncing back of light waves observed when light waves hit ice and most of them bounce off and radiate back into space is called reflection.

What are light waves?

Light waves are a form of waves which produces visible sensitization of the eyes

Light waves have properties of waves such as:

  • reflection
  • refraction
  • diffraction
  • interference, etc.

When light waves hit ice, most of them bounce off and radiate back into space.

This property of light waves is known as reflection.

When light waves hit ice, most of them bounce off and radiate back into space, hence, ice is best described as a reflective surface.

What is a Reflective surface?

A reflective surface is one which can cause incident light to bounce back (reflection).

According to this question, when light waves hit ice, most of them bounce off and radiate back into space. This means that most of the incident lightreflects off the ice surface.

Therefore, the ice surface is best described as a reflective surface.

Changes to the global climate could include _______.a. changes to temperature
b. changes to pressure
c. changes to precipitation
d. all of the above

Which of the following is not released by trees into the atmosphere?
a. oxygen
b. water vapor
c. ozone
d. none of the above

Answers

1. Answer is d. all of the above.

Climate can be defined as the data collection of weather conditions of a long period of time in a certain area. The weather conditions that affect to the climate are temperature, precipitation, atmospheric pressure, wind and so on. Any changes in weather can change the global climate.

2. Answer is c. ozone.

Trees release oxygen and water vapor into the atmosphere but not ozone. The oxygen gas is released by trees as the by-product of photosynthesis. This is the natural way of production of oxygen gas. Water vapor can be released due to the transpiration of trees.

1. The correct answer is option D. all of the above.

Global climate change will bring changes in temperature such as heat waves, droughts, volcanic eruption, deforestation, extinction of species due to large shift in temperatures, changes in precipitation such as  heavy snowfall, ocean acidification, and ozone depletion.  

2. The correct answer is option C, ozone.  

Ozone is not released by trees into the atmosphere. Plants have chlorophyll and in the presence of sunlight plants uses sunlight and carbon dioxide to form glucose and oxygen.

6CO₂ + 6H₂O  ->  C₆H₁₂O₆ + 6O₂

During transpiration plants exhale water vapor through the stomata, tiny pores that are found on the surface of the leaves.

Thus trees never release ozone into the atmosphere.

In Ernest Rutherford's gold foil experiments, some alpha particles were deflected from their original paths, but most passed through the foil with no deflection. Which statement about gold atoms is supported by these experimental observations?Gold atoms consist mostly of empty space.

Gold atoms are similar to alpha particles.

Alpha particles and gold nuclei have opposite charges.

Alpha particles are less dense than gold atoms.

Answers

According to ErnestRutherford's gold foil tests, the true statement is that space makes up the majority of gold atoms. The correct option is A.

According to Rutherford's studies, the majority of the alphaparticles encountered free space inside the atom since they mostly went through the gold foil with little to no deflection.

This finding helped scientists comprehend that atoms have a small, compact nucleus at their center and are primarily made up of empty space elsewhere in the atom.

The nuclearmodel of the atom was created as a result of the deflection of several alpha particles, which showed that they came into contact with the positively charged atom's nucleus.

Thus, the correct option is A.
