WATER Science is the study of water and its interaction with solids, liquids, gases, and organisms in various Earth systems. Our water science program emphasizes the FUNDAMENTALS of all areas of science as they apply to water, with special emphasis on surface water and GROUNDWATER systems.

ANSWER:

HELLO JANVI GOOD EVENING how are you

Answer :-

58.5 grams of Sodium and 91.5 grams of Chlorine are there in the sample .

EXPLANATION :-

We have :-

→ Percentage of Sodium (Na) = 39 %

→ Percentage of Chlorine (CL) = 61 %

→ Mass of the sample of NaCl = 150 g

________________________________

Mass of Sodium :-

Let the required mass of Sodium in the sample, be "x" grams . So, required mass :-

⇒ (x/150) × 100 = 39

⇒ 100X/150 = 39

⇒ 100x = 39(150)

⇒ 100x = 5850

⇒ x = 5850/100

⇒ x = 58.5 g

Mass of Chlorine :-

Let the required mass of Cholrine in the sample be "y" grams. Now, we have :-

⇒ (y/150) × 100 = 61

⇒ 100y/150 = 61

⇒ 100y = 61(150)

⇒ 100y = 9150

⇒ y = 9150/100

⇒ y = 91.5 g

Answer:

Lavoisier was the first child and only son of a WEALTHY bourgeois family living in Paris. As a youth he exhibited an unusual studiousness and concern for the public good. After being introduced to the humanities and sciences at the prestigious Collège Mazarin, he studied law. Since the Paris law faculty made few demands on its students, Lavoisier was able to spend much of his three years as a law student attending public and private lectures on chemistry and physics and working under the tutelage of leading naturalists. Upon completing his legal studies, Lavoisier, like his father and his maternal grandfather before him, was admitted to the elite Order of Barristers, whose members presented cases before the High Court (Parlement) of Paris. But rather than practice law, Lavoisier began pursuing scientific research that in 1768 gained him admission into France’s foremost natural philosophy society, the Academy of Sciences in Paris.

Pneumatic chemistry

The chemistry Lavoisier studied as a student was not a subject particularly noted for conceptual clarity or theoretical rigour. Although chemical writings contained considerable information about the substances chemists studied, little agreement existed upon the precise composition of chemical elements or between explanations of changes in composition. Many natural philosophers still viewed the four elements of Greek natural philosophy—earth, AIR, fire, and water—as the primary substances of all matter. Chemists like Lavoisier focused their attention upon analyzing “mixts” (i.e., compounds), such as the salts formed when acids combine with alkalis. They hoped that by first identifying the properties of simple substances they would then be able to construct theories to explain the properties of compounds.

It was previously claimed that the elements were distinguishable by certain physical properties: water and earth were incompressible, air could be both expanded and compressed, whereas fire could not be either contained or measured. In the 1720s the English cleric and natural philosopher Stephen Hales demonstrated that atmospheric air loses its “SPRING” (i.e., elasticity) once it becomes “fixed” in solids and liquids. Perhaps, Hales suggested, air was really just a vapour like steam, and its spring, rather than being an essential property of the element, was created by heat. Hales’s experiments were an important first step in the experimental STUDY of specific airs or gases, a subject that came to be called pneumatic chemistry.

In the 1750s the Scottish chemist Joseph Black demonstrated experimentally that the air fixed in certain reactions is chemically different from common air. Black wanted to know why slaked quicklime (hydrated calcium oxide) was neutralized when exposed to the atmosphere. He found that it absorbed only one component of the atmosphere, carbon dioxide, which he called “fixed air.” Black’s work marked the beginning of investigative efforts devoted to identifying chemically distinct airs, an area of research that grew rapidly during the latter half of the century. Thus, pneumatic chemistry was a lively subject at the time Lavoisier became interested in a particular set of problems that involved air: the linked phenomena of combustion, respiration, and what 18th-century chemists called calcination (the change of metals to a powder [calx], such as that obtained by the rusting of iron).

Conservation of mass

The assertion that mass is conserved in chemical reactions was an assumption of Enlightenment investigators rather than a discovery revealed by their experiments. Lavoisier believed that matter was neither created nor destroyed in chemical reactions, and in his experiments he sought to demonstrate that this belief was not violated. Still he had difficulty proving that his view was universally valid. His insistence that chemists accepted this assumption as a law was part of his larger program for raising chemistry to the investigative standards and causal explanation found in contemporary experimental physics. While other chemists were also looking for conservation principles capable of explaining chemical reactions, Lavoisier was particularly intent on collecting and weighing all the substances involved in the reactions he studied. His success in the many elaborate experiments he conducted was in LARGE part due to his independent wealth, which enabled him to have expensive apparatus built to his design, and to his ability to recruit and direct talented research associates. The fact that French chemistry students are still taught the conservation of mass as “Lavoisier’s law” is indicative of his success in making this principle a foundation of modern chemistry

Your Solution:

HYDROGEN was discovered by the English physicist Henry Cavendish in 1766. Scientists had been producing hydrogen for years before it was recognized as an element. Written RECORDS INDICATE that Robert Boyle produced hydrogen gas as early as 1671 while experimenting with iron and acids.

ANSWER:

Weather

Climate

1.

The day to day information of atmospheric changes of a particular area at a specific time is called weather.

Climate is the statistical information of the average weather condition of a specific region for more than 30 years.  

2.

The weather of a PLACE includes the short-term atmospheric condition. Also, these atmospheric conditions can change within a short period like minutes, hours, days, etc.

The climate of a country or zone includes the long-term average atmospheric conditions. Thus, the climate is average weather information observed over decades.

3.

The atmospheric ELEMENTS of weather are air pressure, humidity, WIND, temperature, rain, cloudiness, storms, snow, precipitation, etc. These conditions can affect the weather of the place within a short time.

When the atmospheric elements of weather are observed over the decades, those become the affecting conditions of climate. These conditions can include temperature, humidity, wind, etc.

4.

The weather of a particular location can impact the day to day human life like occupation, transportation, communication, agriculture, etc.

The climate of a country significantly impacts industries, agriculture, the livelihood of the inhabitants of that geographical locale.

5.

Weather conditions change very frequently.

Climate conditions change over a long period.

6.

The meteorological department of a place observes the changes in weather conditions. The study of weather forecasting is known as meteorology.  

Institutes of climate studies observe and predict the changes in climate. This study is called climatology.

or  

1. Write The Basic Difference Between Weather and Climate.

Ans. The primary difference between weather, and climate is the duration over which they are measured. Weather includes the short-term changes of the atmospheric conditions, while climate is the observation of weather for a longer-term.

EXPLANATION:

PHOTOSYNTHESIS is the process by which plants use SUNLIGHT, water, and carbon dioxide to CREATE oxygen and energy in the form of SUGAR.

Answer:If mass is GIVEN,

mole = given mass/molar/atomic mass

If volume is given at STP/NTP,

mole = given volume (in L)/22.4 L

If the no of atoms/molecules is given,

mole = no of atoms/molecules/Avogadro's number

Now see your QUESTIONS once again, here no of molecules of carbon dioxide is given, so we have to APPLY last one.

I.e., mole = no of molecules/Avogadro's number

Here no of molecules = 3.011 × 10²²

Avogadro's number = 6.022 × 10²³

So, mole = 3.011 × 10²²/6.022 × 10²³

= 1/20

= 0.05

Therefore the no of moles is 0.05 of carbon dioxide.
