Answer 2

The concept of continental drift was developed by Alfred Wegener. Climates at different latitudes are similar to one another does not support Wegener's hypothesis. Therefore, option D is correct.

What is wegener's hypothesis ?

Wagner's law, commonly referred to as the law of growing state activity, states that public spending rises as GDP does. Adolph Wagner (1835–1917), a German economist, is credited with discovering it first in his own nation before noticing it in other nations.

On January 6, 1912, Alfred Wegener initially presented his theory to the German Geological Society. According to his theory, the continents were formerly part of a single landmass known as Pangaea before disintegrating and migrating to their current places.

However, Wegener's hypothesis lacked a geological explanation for how the continents might have moved as he predicted over the surface of the globe.

Thus, option D is correct.

Calcium nitrate and calcium carbonate are both ionic compounds.

Calcium nitrate mixed with water behaves as an electrolyte.

Calcium carbonate mixed with water does not behave as an electrolyte.

Explain, in terms of solubility and movement of ions, this difference in behaviour​

Answers

Answer:

Calcium nitrate is soluble in water and dissociate into ions whereas calcium carbonate is insoluble and water and do not form ions.

Explanation:

An electrolyte is a substance which conducts electricity in molten form or when dissolved in water.

The ability of an electrolyte to conduct electricity is due the movement of charged particles called ions. The ions are of two types: negatively charged ions called anions and positively charged ions called cations.

Calcium nitrate is a soluble in water, and when dissolved in water produces two ions; negatively charged nitrate ions,NO₃⁻, and positively charged calcium ions, Ca²⁺. These ions enable it to conduct electricity.

Calcium carbonate on the other hand is insoluble in water, and thus, do not produces any ions capable of carrying current.

How are oxidation states of transition metals indicated in the names of metal
compounds?
A. Prefixes are used to indicate oxidation states.
B. Group numbers are used to indicate oxidation states.
C. Roman numerals are used to indicate oxidation states.
D. Subscripts are used to indicate oxidation states.

Answers

Answer:

The anser is c

Roman numerals are used to indicate oxidation states. Hence, option C is correct.

What is the oxidation state?

An oxidation state is a number given to the atom of an element when participating in a chemical reaction.

Roman numerals are used to indicate oxidation states of transition metals.

The names for transition metal compounds often have roman numerals in them, because the roman numerals indicate the charge on the transition metal. But the oxidation state of Cu in CuO is +2, and the oxidation state of Cu in [tex]Cu_2O[/tex] is +1. Name metal first and charge and transition metal with a roman numeral.

The transition metals may form more than one ion, thus it is needed to be specified which particular ion we are talking about. This is indicated by assigning a Roman numeral after the metal. The Roman numeral denotes the charge and the oxidation state of the transition metal ion.

[tex]Fe^{2+}[/tex] would be named iron (II) and [tex]Fe^{3+}[/tex] would be named iron (III).

Hence, option C is correct.

An ionic compound is a chemical compound of ions held together by electrostatic forces termed ionic bonding

Answer:

Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons, giving them a net positive or negative charge. Metals tend to lose electrons, so they become cations and have a net positive charge. Ions of opposite charge are held together by very strong ionic bonds within the compound.

Answers

Answer:

The balanced equation is given below:

4Fe + 3O2 —> 2Fe2O3

Explanation:

Fe + O2 —> Fe2O3

The above equation can be balance by doing the following:

Fe + O2 —> Fe2O3

There are 2 atoms of O on the left side and 3 atoms on the right side. It can be balance by putting 3 in front of O2 and 2 in front of Fe2O3 as shown below:

Fe + 3O2 —> 2Fe2O3

There are 4 atoms of Fe on the right side and 1 atom on the left side. It can be balance by putting 4 in front of Fe as follow:

4Fe + 3O2 —> 2Fe2O3

Thus, the equation is balanced

l is the angular momentum / azimuthal quantum number  

ml, the magnetic quantum number  

ms, the electron-spin quantum number  

Value of n: positive integer  

value of l: s = 0, p = 1, d = 2, f = 3 , ..(n-1)

Glacial evidence found in South America, do indicate how evidence of climate change has supports the theory of continental drift.

Climate change occurs daily all over the world. This is largely due to man's activities that has affected the atmosphere and the earth.

Continental drift is simply known as the theory that states that the continents at a time has formed a single landmass, broke up, and drifted to their present locations.

Glacial evidence in South America has made man to believe more in the continental drift hypothesis.

Chemical equation:

6H₂O + 6CO₂ + energy  →   C₆H₁₂O₆ + 6O₂

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.

Cellular respiration:

Reactants =  Glucose + oxygen

Answers

Explanation:

f= ma

f= 7150 *2

f= 14300N

The force will be equal to 14300N when the mass is 7150 kg and the

acceleration is 2m/s².

What is force?

Force is an external agent that can change a body’s state of rest or motion. Force has a direction and a magnitude so it is a vector quantity. The SI unit of force is Newton and the unit used is Kgm/s².

Force can change the state of a body from rest to motion and can accelerate the speed of a moving body.  The direction of a moving object can be changed by applying force.

The force is expressed by the product of the mass (m) and acceleration (a) of an object. The mathematical equation for force can be expressed in the form of:

F = ma

Given, the mass (m) = 7150 Kg and acceleration (a) = 2 m/s²

Then, force, F = (7150 Kg) × (2 m/s²)

F = 14300 Kgm/s²

or, F = 14300 N

Therefore, the force of the object will be equal to 14300 N.
