Which of the following is not an example of a chemical change?.

Answers

Answer 1
Answer: Well, I can tell you what a chemical change is and you can get your answer from there. A chemical change is when the very make up of the item is totally changed and can not be changed back. When one compound is converted into a totally new compound having different chemical properties. So... melting an ice cube would be physical and not chemical. Crumbling up a piece of paper would be physical becasue if you uncrumble it, it's still a piece of paper. But Burning paper would be considered chemical becasue now it's ash and you can't get that piece of paper back.  I hope this helps!! c:

Which category of minerals is associated with maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential?

Answers

The answer is electrolyte.

That is electrolyte is the type of minerals that is associated with maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential.

Sodium, potassium and chlorides are the macrominerals that are known as the electrolytes, that are very important for the function says  maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential .


Which of these statements best explains why the soil around a volcanic region is fertile? Select one:
a. Volcanoes always contribute to flooding, which enriches the soil.
b. Volcanoes aid in the formation of new rocks, which help form fertile soil.
c. Particles released in the air by volcanoes fall to the ground and enrich the soil.

Answers

Answer:

The correct statement is option c, that is, particles discharged in the air by volcanoes fall to the ground and enrich the soil.  

Explanation:

The eruptions of volcanoes lead to the dispersion of ash over the broader regions surrounding the site of eruption. On the basis of the chemistry of the magma, the ash will be comprising different concentrations of soil nutrients. While the major elements found in the magma are oxygen and silica, the eruptions also lead to the discharging of carbon dioxide, water, hydrogen sulfide, sulfur dioxide, and hydrogen chloride.  

In supplementation, the eruptions also discharge bits of rocks like pyroxene, potolivine, amphibole, feldspar that are in turn enriched with magnesium, iron, and potassium. As an outcome, the areas which comprise huge deposits of the volcanic soil are quite fertile.  

Answer:

Option (C)

Explanation:

The volcanic eruptions are usually very destructive but it also has some advantages of which, one is that it makes the soil fertile in the nearby region.

During the time of the volcanic eruption, a large number of pyroclastic materials, blocks and ashes that are comprised of various gases are released, which eventually adds to the soil of the nearby areas. These materials ejected from the volcano are rich in various minerals such as oxygen, silicon, and some amount of CO₂, SO₂, and HCl which facilitates the growth of the soil and increases its productivity.

Thus, the soil around a volcanic region is much fertile.

Hence, the correct answer is option (C).

Determine the mass of 5.20 moles of C6H12 (gram-formula mass = 84.2 grams/mole).

Answers

Hello!

Determine the mass of 5.20 moles of C6H12 (gram-formula mass = 84.2 grams/mole).

We have the following data:

m (mass) = ? 

n (number of moles) = 5.20 moles

MM (Molar mass of C6H12) ≈ 84.2 g/mol

Now, let's find the mass, knowing that:

n = (m)/(MM)

5.20\:\:\diagup\!\!\!\!\!\!\!mol = (m)/(84.2\:g/\diagup\!\!\!\!\!\!\!mol)

m = 5.20*84.2

\boxed{\boxed{m = 437.84\:g}}\end{array}}\qquad\checkmark

Molar mass C₆H₁₂ = 84.2 g/mol

1 mole ---------- 84.2 g
5.20 moles ---- ?

Mass C₆H₁₂ = 5.20 * 84.2 / 1

Mass = 437.84 /1

= 437.84 g
