What is the molar mass of CaF2?
To find the molar mass of calcium fluoride (CaF2), we need to add the molar masses of calcium (Ca) and two fluorine (F) atoms. The atomic mass of calcium is approximately 40.08 g/mol, and the atomic mass of fluorine is about 19.00 g/mol. Since there are two fluorine atoms in calcium fluoride, we calculate the […]
How much gas does a rocket engine use?
The amount of gas a rocket engine uses can vary significantly based on several factors, including the type of rocket, its size, and the mission requirements. For example, the Space Shuttle’s main engines used liquid hydrogen and liquid oxygen, consuming about 12 tons of propellant per second at full throttle during launch. Generally, rocket engines […]
Rationalize the difference in physical properties in terms of intermolecular forces for benzene (C6H6) and naphthalene (C10H8)
Benzene (C6H6) and naphthalene (C10H8) are both aromatic hydrocarbons, but they exhibit significantly different physical properties such as boiling points and melting points. The boiling point of benzene is approximately 80°C, while naphthalene has a boiling point of 218°C. Similarly, benzene has a melting point of 6°C compared to naphthalene’s higher melting point. The key […]
What class of coal has the highest heating value?
The class of coal that has the highest heating value is anthracite. Anthracite is a type of coal that is known for its high carbon content, typically ranging from 86% to 97%. This high carbon content results in a higher energy density compared to other types of coal. Anthracite coal burns cleaner and produces a […]

What is 2 times 6?
2 times 6 is 12. This is calculated by taking the number 2 and adding it to itself 6 times: 2 + 2 + 2 + 2 + 2 + 2 = 12 Alternatively, you can think of it as 2 groups of 6, which also totals to 12. Therefore, when you multiply 2 by […]

While cacti are often associated with deserts, they primarily thrive in regions of North and South […]
How many bones and how many muscles are in the human body?
The human body consists of 206 bones in adulthood and approximately 600 muscles. To elaborate, at birth, humans have around 270 bones. However, as we grow, some bones fuse together, resulting in the typical 206 bones in a fully grown adult. These bones make up the skeleton, which supports and protects our body structures. On […]
