The properties of a substance are not affected by chemical reactions.

A) true
B) false

Answers

Answer 1

Answer:

A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Explanation:

Answer 2

The statement "the properties of a substance are not affected by chemical reactions" is false.

What are physical and chemical properties?

A substance's physical property is a quality that can be seen or quantified without affecting the substance's identity. Color, density, hardness, and melting and boiling points are examples of physical qualities.

A quality of matter that is unrelated to a change in its chemical makeup is called a physical property. Density, color, hardness, melting and boiling points and electrical conductivity are a few common examples of physical qualities.

Chemical changes result in new compounds with different properties from the original ones, as well as new particles and maybe altered particle numbers.

Therefore, the statement is false.

A soil sample contains 40 percent sand, 30 percent clay, and 30 percent silt. What type of soil is present in the sample?
A) clay
B) clay loam
C) silty loam
D) silty clay loam

Answers

silty loam C) will be your answer, if its wrong my test must be different.

The type of soil is present in the sample is silty loam.

What do you mean by silty loam soil?

Loamy Soil is the mixture of clay, sand and silt soil which consists of additional organic matter and is very fertile compared to other types of soil. It is well suited for cultivation as the plant roots get a sufficient amount of water and nutrients for their growth and development.

Moreover, silty clay loam-based samples contain a higher percentage of clay and silt than sand. Due to the relatively small pore spaces of both clay and silt, the contaminant solutes remain adhered to the clay and silt particle surfaces.

Therefore, Shrubs, climbers, grasses and perennials such as Mahonia and New Zealand flax like silty soil. Moisture-loving trees such as willow, birch, dogwood and cypress do well in silty soils.

Which air mass is associated with low relative humidity and high air temperature?

Answers

Answer: Continental tropical.

Over continents, continental air masses form. These air masses contain only modest amounts of humidity. Polar or tropical locations can both support the development of continental air masses.

What air mass is low relative humidity, high air temperature?

A humid air mass that originates over water is the maritime air mass. Over land, air masses with a continental climate are created.

It is referred to as a continental polar air mass because of how cold and dry the air mass that forms over northern Canada is. An air mass that is warm and humid, known as a maritime tropical air mass, forms over the Indian Ocean.

The relative humidity of the air in the house decreases as cold air, which has less moisture than warm air, enters and is heated.

Therefore, Summer air conditioner use, which takes moisture from the air as it functions, can also contribute to low humidity in arid locations.

Answers

Answer:

In spite of the fact that he didn't have any acquaintance with it, Walther Flemming really noticed spermatozoa going through meiosis in 1882, yet he confused this cycle with mitosis. Regardless, Flemming saw that, dissimilar to during standard cell division, chromosomes happened two by two during spermatozoan improvement. This perception, continued in 1902 by Sutton's careful estimation of chromosomes in grasshopper sperm cell improvement, given conclusive insights that cell division in gametes was not simply customary mitosis. Sutton showed that the quantity of chromosomes was decreased in spermatozoan cell division, a cycle alluded to as reductive division. Because of this cycle, every gamete that Sutton noticed had one-a large portion of the hereditary data of the first cell.
