Here is a picture of a hot spring in yellow stone national park match each kind a scientist with an aspect of the hot Spring she
Lady bird [3.3K]

Each kind of scientist is matched with an aspect of the hot spring he or she is most likely to study as follows:

  1. <u>Geologist:</u> rocks around and under the hot spring.
  2. <u>Ecologist:</u> relationships between organisms and the hot spring.
  3. <u>Sociologist:</u> human behavior around the hot spring.
  4. <u>Meteorologist:</u> atmosphere and weather around the hot spring.

<h3>What is a scientific observation?</h3>

A scientific observation can be defined as an active acquisition of knowledge (information) through one of the sense organs, while using scientific tools and instruments.

<h3>The types of scientific observation.</h3>

In Science, there are two main types of scientific observation and these include the following:

  • Qualitative observation
  • Quantitative observation

<h3>What is a hot spring?</h3>

A hot spring can be defined as a natural or an artificially-induced phenomena in which very hot groundwater flows out from the Earth's crust due to the heat present in the geosphere.  

In this exercise, you're required to match each kind of scientist with an aspect of the hot spring he or she is most likely to study as follows:

  1. <u>Geologist:</u> rocks around and under the hot spring.
  2. <u>Ecologist:</u> relationships between organisms and the hot spring.
  3. <u>Sociologist:</u> human behavior around the hot spring.
  4. <u>Meteorologist:</u> atmosphere and weather around the hot spring.

What is the name of this hydrocarbon?
jenyasd209 [6]

Answer:

2-methylebutane

Explanation:

it is a hydrocarbon and there is a specific Rule for its nomenclature.

that is known as IUPAC naming system. According to it

  • The compound that has all single bonds name ends on ane.
  • Names according to the number of Carbons,

                * For one carbon compound it is known as methane,

                * For 2 ethane,

                * For 3 propane

                * For 4 Butane and so on.

  • select the longest chain of compound
  • Start numbering with lowest substituted position at carbon
  • branch compound name as Iso and neo as whole

So keeping in mind the compound can be named as

2-methylebutane

  • As the longest chain contain four carbon atoms so it will name as butane
  • The substitution of methyl group is on C-2

*Note: it can also named as isopantane as it is branched and have five carbons but it could not be 3-isopentane.

The main constituent of gallstones is cholesterol. Cholesterol may have a role in heart attacks and blood clot formation. Its el
Nataly [62]

The main constituent of gallstones is cholesterol. Cholesterol may have a role in heart attacks and blood clot formation. Its elemental percentage composition is 83.87% C, 11.99% H, and 4.14% O. It has a molecular weight of 386.64 amu. Empirical formula is C₃H₄O₁ and Molecular formula is 7(C₃H₄O₁).

<h3>What is Empirical Formula ?</h3>

Empirical formula is the simplest whole number ratio of atoms present in given compound.

Element   %   Atomic mass   Relative no. of atoms  Simplest whole ratio

C            83.87       12                     \frac{83.87}{12} = 6.98                   \frac{6.98}{0.25} = 3

H            11.99         1                       \frac{11.99}{1} = 11.09                  \frac{11.09}{0.25} = 4

O            4.14          16                      \frac{4.14}{16} = 0.25                    \frac{0.25}{0.25} = 1

Thus the empirical formula is C₃H₄O₁.

<h3>How to find the Molecular formula of compound ?</h3>

Molecular formula = Empirical formula × n

n = \frac{\text{Molecular weight}}{\text{Empirical formula weight}}

  = \frac{386.64}{56}

  = 7

Molecular formula = Empirical formula × n

                               = 7 (C₃H₄O₁)

Thus from the above conclusion we can say that The main constituent of gallstones is cholesterol. Cholesterol may have a role in heart attacks and blood clot formation. Its elemental percentage composition is 83.87% C, 11.99% H, and 4.14% O. It has a molecular weight of 386.64 amu. Empirical formula is C₃H₄O₁ and Molecular formula is 7(C₃H₄O₁).

What do isotopes have in common
alexira [117]

Answer:

Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

How many moles of zinc are in 4.70 kg of zinc?
faust18 [17]
First we convert kg to g
1kg =1000g
4.70=x(gram)
4.70×1000÷1=4700g
now:
number of moles=mass÷molarmass
number of moles=4700÷65.4
number of moles=71.86moles.
