The answer is B
HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond. The correct option is option B.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion. Covalent bond is weaker than ionic bond.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron.

Nitroglycerin contains 60% as many carbon atoms as hydrogen atoms, three times as many oxygen atoms as nitrogen atoms, and the same number of carbon and nitrogen atoms. The number of moles in 1.00g of nitroglycerin is 0.00441. What is the molecular formula?
Answer:
C₃H₅N₃O₉
Explanation:
Molar mass of nitroglycerin (Ratio of mass and moles of the compound) is:
1.00g / 0.0041mol = 226.8g/mol
We can write the equations:
0.6H = C (1)
-60% as many carbon atoms as hydrogen atoms-
3N = O (2)
C = N
Using as basis the atoms of Carbon:
Carbon = 1
Nitrogen = 1
Oxygen = 3
Hydrogen = 1/0.6 = 1.67
A molecular formula has just whole numbers. This ratio of atoms times 3:
Carbon = 3
Nitrogen = 3
Oxygen = 9
Hydrogen = 5
C₃H₅N₃O₉. Molar mass of this formula is:
C = 12.01g/mol*3 = 36.03g/mol
H = 1.01g/mol*5 = 5.05g/mol
N = 14g/mol*3 = 42g/mol
O = 16g/mol*9 = 144g/mol
Molar mass:
36.03g/mol + 5.05g/mol + 42g/mol + 144g/mol = 227g/mol ≈ 226.8g/mol
That means molecular formula of nitroglycerin is:
C₃H₅N₃O₉The molecular formula of nitroglycerin is C₃H₅O₉N₃
Mass of nitroglycerin = 1.00 g
A number of moles of nitroglycerin = 0.0041 mol
It is required to calculate the molecular formula of nitroglycerin.
What is the empirical formula?An empirical formula tells us the relative ratios of different atoms in a compound.
The molecular formula of nitroglycerin can be estimated with the help of empirical formula.
The molar mass of nitroglycerin (Ratio of mass and moles of the compound) is:
1.00g / 0.0041mol = 226.8 g/mol

What is specific heat? How are the factors affecting it?
Answer:
Specific heat, ratio of the quantity of heat required to raise the temperature of a body one degree to that required to raise the temperature of an equal mass of water one degree.
Explanation:
by dividing the heat capacity by the quantity of substance in a body, the resulting specific heat capacity is a function of the structure of the substance itself. In particular, it depends on the number of degrees of freedom that are available to the particles in the substance, each of which type of freedom allows substance particles to store thermal energy.

At which point in its orbit is a planet traveling fastest
Answer:
The fastest a planet moves is at perihelion (closest) and the slowest is at aphelion (farthest).
Explanation:
A planet travels fastest when the planet is closest to the sun also known as the perihelion.
What is an orbit?An orbit is a regular, repeating path that one object in space takes around another one.
The planet moves faster when it is nearer the Sun and slower when it is farther from the Sun.
A planet moves with constantly changing speed as it moves about its orbit.
The fastest a planet moves are at perihelion (closest) and the slowest is at aphelion (farthest).
The force of gravity acting on a planet is equal to its mass times its centripetal acceleration.
Force of gravity = [tex]\frac{m v^2}{r}[/tex]
The force of gravity is defined by Newton's law of universal gravitation as:
Force of gravity = [tex]\frac{mMG}{r^2}[/tex]
Therefore:
[tex]\frac{mMG}{r^2}[/tex] = [tex]\frac{m v^2}{r}[/tex]
[tex]\frac{MG}{r}[/tex]= [tex]v^2[/tex]
According to the equation if v increases r decreases.
Hence, the planet is moving fastest when it's closest to the sun, also known as the perihelion.
