The biotic factors are bacteria soil, dead leaves, and stream water.

<h3>What is an abiotic factor?</h3>

An abiotic factor is a non-living part of an ecosystem that shapes its environment.

Biotic and abiotic factors make up a community via interaction.

Biotic factors are considered living things (having "life") while abiotic factors are simply non-living things.

The dead leaves of plants are an abiotic factor, the bacteria in soil are living matter and stream flowing, etc.

Hence, the biotic factors are bacteria soil, dead leaves, and stream water.

andre [41]

Answer:

1.0 *10^(-4) mol

Explanation:

For gases:

n1/n2 = V1/V2

n1/3.8*10^(-4) mol = 230 mL/ 860 mL

n1 = 3.8*10^(-4)*230/860 = 1.0 *10^(-4) mol

As you move from left to right across a period, what happens to the atomic radii?
GrogVix [38]

Answer:

They decrease, because of the stronger effective nuclear charge.

Explanation:

  • Atomic radii decreases from left to right across a period.
  • This is due to the increase in the no. of protons and electrons through the period.
  • One proton has a greater effect than one electron.
  • So, electrons are attracted towards the nucleus and resulting in a smaller atomic radii.

<em>Thus, the right choice is: They decrease, because of the stronger effective nuclear charge.</em>
