7 0

The correct answer would be communicating. The scientific skill that involves sharing what you have learned with others is communicating. Communicating happens when there is an exchange of thoughts or ideas from two or more people. These ideas often differ because every individual's learning style is different. Therefore, what you have known may not be known to others so this is when the communicating skill enters: exchange and sharing of ideas.

It is called communication. It is the skill in which we share what we learn.

Which of the following samples will have the greatest volume at STP?a. 22 g Neb. 22 g Hec. 22 g O2d. 22 g Cl2 e. All have the sa

sammy [17]

Answer:

22g of He

Explanation:

Volume of gas at STP is given as :

Volume occupied(dm³) = number of moles x 22.4dm³mol⁻¹

In order to solve this given problem, we would first find the number of moles from the different masses of atoms and molecules given.

Number of moles = $\frac{mass }{Molar mass}$

Now, let us obtain the molar mass of the given atoms and elements:

For Ne; molar mass is the atomic mass = 20gmol⁻¹

He = 4gmol⁻¹

O₂ = (16 x2)gmol⁻¹ = 32gmol⁻¹

Cl₂ = (35.5x2)gmol⁻¹ = 71gmol⁻¹

Number of moles of Ne = $\frac{22}{20}$ = 1.1mol

Volume occupied by Ne at STP = 1.1 x 22.4 = 24.64dm³

Number of moles of He = $\frac{22}{4}$ = 5.5mol

Volume occupied by He at STP = 5.5 x 22.4 = 123.2dm³

Number of moles of O₂ = $\frac{22}{32}$ = 0.688mol

Volume occupied by O₂ at STP = 0.688 x 22.4 = 15.4mol

Number of moles of Cl₂ = $\frac{22}{71}$ = 0.3099mol

Volume occupied by Cl₂ at STP = 0.3099 x 22.4 = 6.94dm³

. Why do some people require bifocals (

tresset_1 [31]

Answer:

Bifocal lenses are used for people who are both nearsighted and farsighted. It is common for people who are over the age of 40 to begin to notice a change in their vision and require the need for bifocals. As we age, our eyes begin to have trouble focusing on objects at different distances away.

What makes zebra mussels an invasive species?

Pani-rosa [81]

Answer:

Zebra mussels negatively impact ecosystems in many ways. They filter out algae that native species need for food and they attach to--and incapacitate--native mussels. Power plants must also spend millions of dollars removing zebra mussels from clogged water intakes.

Mitosis occurs where in the body? Where does meiosis occur?

kakasveta [241]

Polygenic traits are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of other animals.
