What is smaller then an atom?
Alexxx [7]

Answer:

In the physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles.

What is the difference between the control group and the experimental group in a experimental study
Ierofanga [76]
A control group is going to be something that you don’t “experiment on or change. It is grown or watched under normal conditions. This way you have a medium to say how things are “supposed” to go.

The experimental group is going to be where you “experiment” and change the normal conditions to see what outcome will occur ( under different conditions then normal )

LBiogeochemical cycles provide
lapo4ka [179]

Answer:

The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.

A normal breath takes in about 1.0 L of air. If air has an average molar mass of 28.8 g per 1 mol and has a density of 0.97 g/mL
Ann [662]

Taking into account the definition of density and Avogadro's Number, you take 2.0286×10²⁵ molecules of air.

<h3>What is density</h3>

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

<h3>What is Avogadro's Number</h3>

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

<h3>Amount of molecules of air</h3>

In this case, you know that:

  • Density= 0.97 \frac{g}{mL}
  • Volume= 1 L= 1000 mL

Replacing in the definition of density:

0.97 \frac{g}{mL}=\frac{mass}{1000 mL}

Solving:

mass= 0.97 \frac{g}{mL}  ×1000 mL

<u><em>mass= 970 g</em></u>

Air has an average molar mass of 28.8 g per 1 mol. Then 970 grams are contained in 33.68 moles.

Now, considering the definition of Avogadro's number you can apply the following rule of three: If 1 mole of air contains 6.023×10²³ molecules, 33.68 moles contains how many molecules?

amount of molecules = (33.68 moles× 6.023×10²³ molecules)÷ 1 mole

<u><em>amount of molecules= 2.0286×10²⁵ molecules</em></u>

Finally, you take 2.0286×10²⁵ molecules of air.
