MY BIOME IS RAINFOREST, ANSWER THE QUESTIONS
i tried i hope this helps hun word “rain forest” implies that these are the some of the world’s wettest ecosystems. Rain forests generally receive very high rainfall each year, although the exact amount varies among different years and different rain forests. For example, South America’s tropical rain forests receive between 200 and 300 centimetres (80 and 120 inches, or 6.5 to 10 feet!) of rain in a typical year. Despite relatively consistent rain in these ecosystems, there are distinct dry seasons in some rain forests. Wet and dry seasons of tropical rain forests vary in their timing, duration and severity around the globe. Tropical rain forests also have high humidity; about 88% during the wet season and approximately 77% in the dry season.

Think and discuss: Why is there an attraction between the two ions in this chemical bond?
Answer:
These ions are attracted to each other due to its opposite charges. This force of attraction is called an ionic bond because it is formed by the attraction of two atoms with opposite charges.
Explanation:
LOL im answering this question for a gizmo assingment rn
There is an attraction between two ions in a bond because they are composed of opposite charges.
In science, we know that opposite charges attract while like charges repel according to the first law of electrostatics. Ionic bonds are composed of metal and non metal ions. The metal ions are positively charged while the nonmetal ions are negatively charged.
These oppositely charged ion pair constitute the ionic bond therefore, there an attraction between the two ions in this chemical bond because they are unlike charges.

An irregularly shaped stone was lowered into a graduated cylinder holding a volume of water equal to 2.0 mL. The height of the water rose to 7.0 mL. If the mass of the stone was 25 g, what was its density?
Answer:
Density = 5 g/mL
Explanation:
Given data:
Volume of water = 2.0 mL
Volume of water + stone = 7.0 mL
Mass of stone = 25 g
Density of stone = ?
Solution:
Volume of stone = (volume of water + stone) - volume of water
Volume of stone = 7.0 mL - 2.0 mL
Volume of stone = 5.0 mL
Density of stone = mass/ volume
Density = 25 g/ 5.0 mL
Density = 5 g/mL

Observe the image of sodium. List the properties you see.
Part 2
Observe the image of hydrogen chloride. List the properties you see.
Answer:
Observable properties of sodium from the image:
1. It's slivery-white solid
2. It's shiny and bright
3. Looks soft
4. Looks waxy
Observable properties of hydrogen chloride from the image:
1. It is a colorless liquid
2. It is transparent
Explanation:
Sodium is known to be a metal that is silvery-white and waxy in appearance. The metal is bright and shiny especially when it is cut. It can be cut with a knife due to it soft nature. It is reactive and has low melting point. It actually reacts with water to form sodium hydroxide.
Hydrogen chloride (known to be hydrochloric acid) is a transparent and colorless substance. It is used in manufacturing plastics, textile, fertilizers, etc. The concentrated hydrogen chloride is very corrosive.
The above are what I can see from the image.

Explanation:
How many atoms of each element in the compound 2(PO4)
Answer:
8 & 13
Explanation:
help me please with my science test questions 5 and 6
Answer:
5. Element J has the highest atomic number
6. Elements G and L have the same number of electrons in their outermost shell.
Explanation:
The periodic table of elements is a table which shows the arrangement of the elements in the order of increasing atomic number. Starting from the topmost left-hand side of the table where the element with the least atomic number is placed, and going across the table from left to right and down to the lowest point to the right of the table, where the element with the highest atomic number is located, the atomic number of elements progressively increases.
Looking at the table, it can be seen that the element J is found at the lowest point to the right of the table. Therefore, element J has the highest atomic atomic number.
6. In the periodic table, elements are arranged into groups and periods. The groups are the columns while the periods are the rows. Elements in the same column or group have the same number of electrons in their outermost shell. Therefore, element G and L have the same number of electrons in their outermost shell.

Reading a Periodic TableBalancing EquationsUsing Dimensional AnalysisExplanation:Step 1: Define
[RxN - Unbalanced] Mg (s) + HCl (aq) → MgCl₂ (aq) + H₂ (g)
[RxN - Balanced] Mg (s) + 2HCl (aq) → MgCl₂ (aq) + H₂ (g)
[Given] 2.28 mol Mg (s)
Step 2: Identify Conversions
[RxN] 1 mol Mg = 2 mol HCl
Molar Mass of H - 1.01 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of HCl - 1.01 + 35.45 = 36.46 g/mol
Step 3: Stoichiometry
Set up: [tex]\displaystyle 2.28 \ mol \ Mg(\frac{2 \ mol \ HCl}{1 \ mol \ Mg})(\frac{36.46 \ g \ HCl}{1 \ mol \ HCl})[/tex]Multiply: [tex]\displaystyle 166.258 \ g \ HCl[/tex]Step 4: Check

Explanation:
Prokaryotes and Eukaryotes both fall in
the category of living things.
True
False
All living organisms falls to either of the prokaryote or eukaryote categories. Thus, the correct option is true.
Living organisms are classified into 2 based on the type of cells they are made of. These are:
Prokaryotes: those whose cells lack nucleus and membrane bound organelles. Examples include bacteria and cyanobacteriaEukaryotes: those whose cells are more complex with nucleus and membrane bound organelles. They include the protists, plants, animals, and fungi.Hence, it is safe to say that prokaryotes and eukaryotes both fall in the category of living things. You have to be living in order to be classified as either.

0.55g/L
Explanation:
Given parameters;
Mass of salt = 55g
Volume of water = 100L
Unknown:
g/L concentration = ?
Solution:
To solve this problem, we must understand that concentration is the amount of solute per solution
g/L concentration = [tex]\frac{55}{100}[/tex] = 0.55g/L

The Faruq family uses 548 liters of water per day.
The Chammas family uses 3 times as much water
per day.
Answer:
11508 liters
Explanation:
The Faruq family uses 548 liters of water per day. The Chammas family uses 3 times as much water per day. How much water does the Chammas family use per week?
Solution:
The amount of water used by the Chammas family is three times that of the Faruq family per day, hence:
Amount of water used by Chammas family in a day = 3 * water used by Faruq family in a day
Amount of water used by Chammas family in a day = 3 * 548 = 1644 liters
The amount of water used by the Chammas family in a week = 1644 liters per day * 7 days in a week = 11508 liters
Therefore 11508 liters of water was used by the Chammas family in a week
