Answer:  1. Pine, Cedar, Mango

2. Maple and ELm.

3. Mango. Elm and Maple.

4. Pine and Cedar.

Explanation:

Before I give the answers, I would like to explain the listed type or category of trees given in the question.

Evergreen;

Evergreen plants are those plants that retains its leaves throughout the year and into the following year. Their leaves are usually thicker and leatherier when compared to deciduous tree. Example of evergreen include most conifers species (such as blue spruce, pine, cedar) and mango.

Deciduous trees;

These are huge flowering plants that are found in many parts of the world. They are normally round shaped with branches spread out as they grow.

They include oaks, maples and beeches. The word deciduous means to “fall off”.

Hardwoods;

This is a wood from dicot trees. They are classified as Angiosperms i.e. flowering plants, which is the largest group of land plants. Hardwoods usually have broad leaves, enclosed nuts or seed.

Some notable examples of hardwoods include; balsa, beech, mahogany, oak etc.  

Conifers;

They are division of vascular land plants containing a single extant class. They are gymnosperms, cone-bearing seed plants and are normally perennial woody plants with secondary growth. Popular examples include; cedar, pine, redwoods, spruces etc.

1. Evergreen are plants that maintain their leaves in all seasons and include trees such as Pine, Cedar and Mango.

2. Deciduous trees lose their leaves seasonally and include trees such as Maple and Elm.

3. Hardwoods reproduce using flowers and have broad leaves such as Mango, Elm, Maple.

4. Conifers leaves are generally thin and needle-like, while seeds are contained in cones. Conifers include Pine and Cedar.

Acetone major species present when dissolved in water
jek_recluse [69]

Answer: acetone molecule ( CH₃-CO-CH₃)


Explanation:


1) Acetone is CH₃-CO-CH₃


2) That is a molecule (build up of covalent bonds).


3) When dissolved, covalent bonded compounds remain as separate molecules, then it is said that the major species present in the solution is the molecule. The molecules of acetone are surrounded (sovated) by the molecules of water.


This as opposed to the case of ionic compounds that ionize. When a compound as NaCl dissolves in water, it ionizes completely, so the major speceies are not NaCl formulas, but the ions Na⁺ and Cl⁻, not molecules.


That leads to the answer: the major species present when acetone is dissolved in water is the molecules of acetone (you do not need to state the fact that the molecules of water are part of the solution, because that is not the target of the question).

How many grams of CaF2 are present in 1.25 L of a 0.15 M solution of CaF2? How do I find the grams I am confused on that part?
dybincka [34]

Answer:

Mass = 14.64 g

Explanation:

Given data:

Volume of solution = 1.25 L

Molarity of Solution = 0.15 M

Mass of CaF₂ = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

We will calculate the number of moles of CaF₂ and then determine the mass by using number of moles.

0.15 M =  number of moles of solute / 1.25 L

number of moles of solute = 0.15 M ×  1.25 L

number of moles of solute = 0.1875 mol/L × L

number of moles of solute = 0.1875 mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 0.1875 mol ×78.07 g/mol

Mass = 14.64 g
