Answer:
Molecular formula = C₁₀H₂₀
Explanation:
Given data:
Empirical formula = CH₂
Molar mass = 140.27 g/mol
Molecular formula = ?
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Now we will calculate the empirical formula mass.
CH₂ = 12 × 1 + 1× 2
CH₂ = 12 +2
CH₂ = 14
n = 140.27 / 14
n = 1
0
Molecular formula = n (empirical formula)
Molecular formula = 10 (CH₂)
Molecular formula = C₁₀H₂₀
Answer:
The foam board has a larger gravitational force but it also has a very large air resistance force. The net (total) force on the foam board will give it a smaller acceleration than paper.
Explanation:
The air molecules get knocked away and take some of the kinetic energy away from the object, which makes the object slow down
Nitrogen is the chemical element with the symbol N and atomic number 7. ... At standard temperature and pressure, a colourless and odorless atomic gas with the formula N. nitrogen forms about 78% of Earth's atmosphere.
Answer:
Sodium Hydroxide is an ionic compound formed by two ions, Sodium Na+ and Hydroxide OH− . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it take one +1 sodium ions to balance the one -1 hydroxide ion. This will make the formula for Sodium Hydroxide NaOH
