Answer:

The Following are the matching to this question:

1 \to c\\2 \to  b\\3 \to   a\\4   \to  e \\5 \to  d    \\6 \to  f

Explanation:

  1. It includes creating assumptions, extracting predictions through logical outcomes, and experimentation observation based on those projections.  
  2. Every information gathered only with sense is also an observation. It expresses concern relating to scientific research. It also helps research scientists gather data.  
  3. Its independent variable inside an analysis is a controlled variable. It's also called "manipulated," because it can change its parameter, which is controlled one.  
  4. The suggested explanation for an occurrence is a hypothesis. It belongs to the scientific method. That's an experimental forecast, which is checked.  
  5. The experiment manipulates the important variables, calculates the dependent variable, controls any alien variables.
  6. It "reacts" to improvements inside an experiment that they make. It is the result or consequence of an experiment.

The radius of a xenon atom is 1.3×10−8cm. a 100-ml flask is filled with xe at a pressure of 1.2 atm and a temperature of 281 k .
vladimir2022 [97]
Radius of Xenon = 1.3Ă—10â’8 cm 
Volume = 100 ml = 0.1 L 
Pressure P = 1.2 atm = 121.59 Kpa 
Temperature = 281 K 
R = Gas Constant = 8.31 J mol^-1 K^-1 
Now find the number of atoms 
PV = nRT => n = PV / RT 
n = (121.59 x 0.1) / (8.31 x 281) = / 2335.11 = 0.0052 
Number of atoms in a mole is same as Avogadro constant A, which is 6.02 x
10^23 particles.  
n = number of atoms= 0.0052 
N = number of particles 
 Avogadro constant A = 6.02 x 10^23 
n = N/A => N = n x A = 0.0052 x 6.02 x 106^23 = 3.13 x 10^20 
Volume of Xe atom which would be a sphere = (4/3) x pi x r^3 
Volume = = (4/3) x 3.14 x (1.3Ă—10â’8)^3 = 9.2 x 10^-24 
Volume occupied by these particles = n x Volume = 3.13 x 10^20 x 9.2 x
10^-24 = 0.00288
 Fraction of volume will be = 0.00288 / 0.1 = 0.0288

What is an air mass? Where on Earth might you find a hot and dry air mass?
igor_vitrenko [27]
An air mass is a large volume of air in the atmosphere thats mostly uniform in temperature and moisture. Air masses can extend thousands of kilometers across the surface of the Earth, and can reach from ground level to the stratosphere/10 miles into the atmosphere. an air mass over northern Canada is a continental polar air mass and is cold and dry. One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid.

How many moles of Ca are in 7.2x10^25 molecules of Ca<br> (show work)
Gre4nikov [31]

Answer:

<h2>119.60 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{7.2 \times  {10}^{25} }{6.02 \times  {10}^{23} }   \\  =119.60132...

We have the final answer as

<h3>119.60 moles</h3>

Hope this helps you
