Answers
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.Conclusively, we can therefore say that Glacial evidence found in South America, do indicate how evidence of climate change has supports the theory of continental drift.

Further explanationEach orbital in an atom consists of 4 quantum numbers
n is the principal quantum number.
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)
ml value: between -l to + l
ms value: +1/2 or -1/2
So for L=5, mL value : -5 to +5

To what pressure must a gas be compressed in order to get into a 3.00 cubic foot
tank the entire weight of a gas that occupies 400.0 cu. ft. at standard pressure?
Answers
Answer:
133.3atm
Explanation:
Given parameters:
Initial volume = 400ft³
Final volume = 3ft³
Initial pressure = 1atm
Unknown:
Final pressure = ?
Solution:
To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P and V are pressure and volume
1 and 2 are initial and final states;
Insert parameters and solve;
1 x 400 = P₂ x 3
P₂ = 133.3atm

Answers
Answer:
A. Atoms gain, lose, or share electrons to achieve a full valence shell
Explanation:
The octet rule is best explained as the process in which atoms lose or gain or share electrons to achieve a full valence shell.
In this process bonds are formed when there is an attraction between the two substances. For electrovalent compounds, an atom will lose electrons or gain electron to form an ion, the electrostatic attraction causes the bond formation. Covalent compounds, form by sharing of electrons.Therefore, the octet rule is attained when atoms gain full valence configuration.

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.
An ionic compound is
A.a salt
B.held together by a transfer of electrons
C.composed of anions and cations
D.held together by sharing of valence electrons

If the mass is 7150 kg, and the
acceleration is 2 m/s2, then what is the
force?
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.

Write the general formula of an alkane and use this to predict the 97th member
of the alkane series.
Answers
Explanation:
The general formula of an alkane is given as;
CₙH₂ₙ₊₂
n is the number of the member;
For the 97th member in the series;
n = 97;
2n + 2 = 2(97) + 2 = 196
So, the 97th member is;
C₉₇H₁₉₆
This is how to apply the formula of alkanes which are saturated hydrocarbons to find any member of the series.
