What is a solar system?
A solar system is the gravitational bound system comprising the sun and the objects aligned in the orbit revolving around the sun. The foundation of the solar system is mediated billions of years ago with the huge interstellar cloud collapse.
The planets are present in the orbit bounded by the gravitational force of the sun and revolve around it. Earth is the planet that is said to have only one having the five elements that support life namely. fire, air, water, soil, and space.
The solar system is comprised of 9 planets with the nearest to the sun being mercury, and the farthest being Pluto. Earth is arranged as the third planet from the distance from the sun and is located between Venus and Mars.

What is electronegativity?
Electronegativity is a property of an element which show the tendency of that element to accept electrons from other element. When an atom accept electrons, it gets a negative charge, the charge increase with the increase of accepting number of electrons.
Chlorine is a gas and is highly acidic. It has the highest electronegativity because it has the highest tendency to form a covalent bond with other element.
Chlorine has seven electrons in its outer shell, and it needs only one electron to complete its octave equal to the noble gas configuration.
Thus, the correct option is D. Cl.

Answer:
Cl
Explanation:
The electronegativity follow the trend that the higher the element is the more electronegative he is, for exemplo, in F, Cl and Br are all from the same group, 17A, put F has the lowest atomic number, followed by Cl and Br is the last, because of that F is the more electronegative from them, followed for Cl and Br is the element with lowest electronegativity.
And this trend also says that the element that are on the right of the table will have the higher electronegativity, for exemplo F, K and Be, all of the will have electron on the second band of valence but F is for the group 17A, K is from the 1A and Be is form the 2A. Because of that F is, one again, the one with the highest electronegativity followed by Be and K is the one with the lowest electronegativity of them all.

Answer:
The mechanical energy of the system increases, provided there is no loss of energy due to friction. The energy would transform to kinetic energy when the speed is increasing. The mechanical energy of the system remains constant provided there is no loss of energy due to friction.
Explanation:
Final answer:
An object's mechanical energy generally increases as its velocity increases. This is because mechanical energy is the sum of an object's kinetic and potential energy, and kinetic energy is directly proportional to the square of its velocity.
Explanation:
In physics, mechanical energy is the energy that an object has due to its motion (kinetic energy) and position (potential energy). When an object's speed or velocity changes, specifically increases, so does its kinetic energy, as kinetic energy is directly proportional to the square of the object's velocity. Essentially, if an object's velocity doubles, its kinetic energy would quadruple. However, this does not take into account variables like air resistance, friction, or changes in potential energy. In an ideal, frictionless scenario, an increase in an object's velocity directly results in an increase in its mechanical energy.

Answer:
2.2 °C/m
Explanation:
It seems the question is incomplete. However, this problem has been found in a web search, with values as follow:
" A certain substance X melts at a temperature of -9.9 °C. But if a 350 g sample of X is prepared with 31.8 g of urea (CH₄N₂O) dissolved in it, the sample is found to have a melting point of -13.2°C instead. Calculate the molal freezing point depression constant of X. Round your answer to 2 significant digits. "
So we use the formula for freezing point depression:
- ΔTf = Kf * m
In this case, ΔTf = 13.2 - 9.9 = 3.3°C
m is the molality (moles solute/kg solvent)
- 350 g X ⇒ 350/1000 = 0.35 kg X
- 31.8 g Urea ÷ 60 g/mol = 0.53 mol Urea
Molality = 0.53 / 0.35 = 1.51 m
So now we have all the required data to solve for Kf:
- ΔTf = Kf * m
- 3.3 °C = Kf * 1.51 m
- Kf = 2.2 °C/m

Explanation:
A diatomic molecule is defined as the molecule which contains two atoms.
For example, a molecule has two atoms of hydrogen.
Molar mass of a molecule is 2.0 g/mol. Therefore, calculate the mass of 2.0 moles of diatomic hydrogen as follows.
No. of moles =
2.0 mol =
mass = 1 g
therefore, we can conclude that total mass of 2.0 moles of diatomic hydrogen is 1 g.
diatomic hydrogen is written as H2 (2.02 grams H2) <------- if each hydrogen atom is 1.01 grams, then two hydrogen atoms are 2.02 grams 2.0 moles H2 X 2.02 grams H2 ------------- (divide to cancel moles) = 4.04 grams/mole H2 ÷ one mole = 4.04 grams H2
