Answer:

photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it.

Ira Lisetskai [31]

Answer:

In each Amplify Science unit, students figure out

a phenomenon by asking questions, gathering

evidence, and coming up with an explanation of how

the phenomenon works. The Coherence Flowchart

visually represents the storyline of the unit, showing

the coherent flow of questions, evidence, and ideas that

support students as they build complex explanations

of the unit’s anchor phenomenon. The Coherence

Flowchart on the following pages (one chapter per

page) can be used to see the connections between

the questions that drive students’ experiences, the

evidence they gather, the ideas they figure out, and the

new questions that those ideas generate. The diagram

to the right explains the structure of a chapter in the

Which of the following soils is the most porous? Soil A - flat, sorted particles. Soil B - round, sorted particles Soil C - roun
Ksju [112]

Answer: Option (b) is the correct answer.

Explanation:

Porosity means the ease with which a fluid can pass through between a rock or cracks etc.

If particles of a soil are flat and even if they are sorted then there will rarely be any space available for fluid or water to pass through it.

If soil particles are round in shape and are sorted then there will be space available for the fluid to pass through it. Hence, this type of soil will be most porous.

Similarly, if soil particles are round but are unsorted then there will be less space available as compared to sorted particles. This is because particles are placed randomly so, somewhere there will be much less space and somewhere there will be large space available. As a result, soil will not be most porous.

If soil particles are flat and unsorted then there will also be less space available for the fluid to pass through it. Thus, soil will be less porous.

Hence, we can conclude that out of the given options, soil B - round, sorted particles is the most porous.

Calculate the amount of 0.1 M base needed to neutralize 10,000 liters of pH 6.0 water.
musickatia [10]

Answer:

0.1 liters of NaOH.

Explanation:

When the acid solution is neutralized we have:

n_{a} = n_{b}

C_{a}V_{a} = C_{b}V_{b}

Where:

n_{a}: is the number of moles of the acid

n_{b}: is the number of moles of the base

C_{a}: is the concentration of the acid

C_{b}: is the concentration of the base = 0.1 M

V_{a}: is the volume of the acid = 10000 L

V_{b}: is the volume of the base =?

The concentration of the acid can be calculated from the pH:

pH = -log([H^{+}])

[H^{+}] = 10^{-pH} = 10^{-6} M

Now, we can find the volume of the base:

V_{b} = \frac{C_{a}V_{a}}{C_{b}} = \frac{10^{-6} M*10000 L}{0.1 M} = 0.1 L

Therefore, the amount of NaOH needed to neutralize the solution is 0.1 liters.

I hope it helps you!
