Answer:
from the way I understand the question I think the answer is (B)
Explanation:
Because the distribution into shells of oxygen is 2,6 and in sulfur is 2,8,6 and oxygen has a 8th number of electrons and sulfur has the 16th number of electrons
Answer:
The roles of decomposers organisms are to degrade organic matter and contribute to the nutrition of the soil, which involves recycling the chemical elements needed by living organisms.
Explanation:
In nature, decomposers -such as bacteria and fungi- are heterotrophic organisms that require nourishment from organic matter in order to survive, being the last level of the food chains.
<u>The role of decomposers in an ecosystem can be summarized in two main functions</u>:
- <em>Degrading organic matter to convert complex substances into simple substances, which contributes to their own nutrition.</em>
- <em>To provide nutrients to the soil, which will be used by producers, plants, for their growth and development.</em>
An example of this is the degradation of proteins by decomposers, providing nitrogen to the soil that will subsequently be absorbed by plants to synthesize their nutrients.

Answer:
The mass of the acetic acid is 13.5 g
Explanation:
Given;
weight percent of the acetic acid (ratio of solute to total solution), w/w = 98 %
volume of acetic acid, v = 12.83 mL
density of acetic acid, ρ = 1.05 g/mL
density is given by;
density = mass / volume
mass = density x volume
mass of the acetic acid in 12.83 mL = 1.05 g/mL x 12.83 mL
mass of the acetic acid in 12.83 mL = 13.5 g
Therefore, the mass of the acetic acid is 13.5 g
First, convert 2.0 mL of AlCl3 to grams using the density, which is 2.48g/mL. So 2.48g/mL * 2.0 mL = 4.96g. Then find the molar mass of aluminum chloride and divide 4.96 by this number, which is 133.34g. 4.96g*(1mol/133.34g) = .0372 mols AlCl3. Check for significant digits though.
