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.

B. 6

Explanation:

Isotope given:

                      ¹⁴₆C

In specie written as this;  

  Superscript  = Mass number

  Subscript  = Atomic number

To find the protons, it is the same as the atomic number;

Explanation:

Read the following passage and identify the error. During germination, the fertilized egg begins to sprout and grow. Each seed contains an embryo, or tiny plant, and it needs the right condition to grow. These conditions include the basic need of water, the correct temperature, and the right location, which is in the soil. Select the statement that corrects the error in the passage. Seeds are fertilized during germination, not before. Basic conditions include wind, not water. The fertilized egg begins to grow and mature, not an embryo. The fertilized seed begins to grow and sprout, not an egg.

A typical seed consists of a fertilized ovule which forms the embryo. Double fertlization ensures that a structure, the endosperm, surrounds and provide nutrition to the embryo while in a state of inactivity.

During germination, the embryo sprouts and grows given the right conditions of moisture, air, temperature, and other factors that may vary from seeds to seeds.

Answer:

B. bedrock structure.

Explanation:

A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, valley, hills and plateau.

Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.

A convergent plate boundary can be defined as a boundary where two (2) plates move towards each other, usually, resulting in subduction or collision. This action often causes mountain range such as the Himalayas to form by the collision between the plate carrying Eurasia and that of India; as a result of subduction which causes a plate to be forced underneath the mantle, deep ocean trenches are formed such as the Mariana trench.

The Catskills are commonly called mountains but are actually part of the Allegheny Plateau also referred to as Appalachian Plateau. The Catskills are classified as a plateau because of their bedrock structure which is caused by a valley, continental glaciers, and erosion from various watercourse.

Additionally, the Catskills is a mountain which got its name from early Dutch settlers in the United States of America.

Answer:

This compound is HNO2

Explanation:

HNO2 ----> H+ + NO2

When metals and non metals combine in fixed proportion then a chemical compound is formed So, the compound that will be formed from  hydrogen ion and nitrate ion is Hydrogen nitrate.

Chemical formula is a formula where cation and anion combine to form a molecule in fixed proportion. Metals combine in form of cation and non metals combine in form of anion.

Cation is the species that give electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state.

Therefore, the compound that will be formed from hydrogen ion and nitrate ion is Hydrogen nitrate.

Answer:

Molecular formula = C₄H₆

Explanation:

Given data:

Molecular mass of compound = 54 g/mol

Empirical formula = C₂H₃

Molecular formula = ?

Solution:

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass = 12×2 + 3×1 = 27 g/mol

n = 54 / 27

n = 2

Molecular formula = n (empirical formula)

Molecular  formula = 2(C₂H₃)

Molecular formula = C₄H₆

Answer:

Often, chemical changes in the water might result in the release of different minerals such as salt or calcium carbonate. Pressure and heat in the process of creating metamorphic rock can also result in the formation or transformation of minerals.  Minerals in igneous rocks often form where magma has cooled over time.

Explanation:

Minerals only form in certain areas due to presence of specific environment.

Minerals only form in certain areas because of the presence of suitable environmental condition for it. Every mineral needs specific environment for its formation. Without that specific temperature, pressure and some other factors, the mineral can't formed.

Every mineral needs specific environment for its formation which is different from one another so we can conclude that mineral formation needs particular environmental conditions.

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

The Relative Formula Mass of Fe(NO₃)₂ is 179.8524 grams

Explanation:

The Relative Formula Mass is the mass of one mole of a compound expressed in grams, obtained by adding together the Relative Atomic Masses, RAM, of the elements which makes the compound

The Relative Formula Mass of a compound is the same as its Relative Molecular Mass

The relative formula mass of Fe(NO₃)₂ is given as follows;

The relative atomic mass of Fe = 55.845 amu

The relative atomic mass of nitrogen, N = 14.0067 amu

The relative atomic mass of oxygen, O = 15.999 amu

Therefore, we have;

The formula mass of Fe(NO₃)₂ = (55.845 + 2×(14.0067 + 3×15.999)) amu = 179.8524 amu

The Relative Formula Mass of Fe(NO₃)₂ = 179.8524 grams.

Explanation:

A molecule is a substance made up of more than one atom. Most times, the individual atoms of elements are UNSTABLE, hence, their atoms get chemically bonded to one another to form a MOLECULE.

Oxygen is an element denoted by the symbol O. Oxygen is made up of atoms that becomes chemically joined together via covalent bonds i.e each atom of oxygen shares their valence electrons, to form OXYGEN MOLECULE (O2). Oxygen molecule is referred to as a diatomic molecule because it is made up of two of the same atoms.

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.
