Answer:
For the provided compounds, by decreasing chemical shift (ppm), the sequence from left to right is Benzene >> Cyclohexane >> Ethane (CH₂-CH₂) >> Methane (CH₄).
Explanation:
¹H-NMR spectrum, roughly, we can say that the more density of electron around the Hydrogen atom, the lower the shift is. So, in this case methane with the simplest structure, only one Carbon atom, does not cause much effect to reduce the density of electron around the hydrogen, so, it is the lowest.
Ethane and cyclohexane looks similar, but cyclohexane with the ring-structure, six carbon atoms, has more effect than ethane with only 02 carbon atoms. Benzene, with the aromatic ring, which has very strong negativity with electron, so it cause the density of electron on the surrounding hydrogen to be the lowest among the four provided compounds.
Answer: Measures acceleration forces.
Explanation: An Accelerometer is a electromechanical device used to measure acceleration forces. Such forces may be static, like the continuous force of gravity. Dynamic to sense movement or vibrations.
Explanation:
a. → ?
Removing common ions from both sides, we get the net ionic equation:
b. →
No precipitation is occuring.
c. →
Removing common ions from both sides, we get the net ionic equation:
d. →
Removing common ions from both sides, we get the net ionic equation:
9moles of O₂
Explanation:
Given parameters:
Number of moles of KClO₃ = 6moles
Unknown:
Number of moles of O₂ = ?
Solution:
KClO₃ is often known to undergo a decomposition reaction to produce KCl and O₂.
2KClO₃ → 2KCl + 3O₂
From the given equation, we know;
2 moles of KClO₃ will produce 3 mole of O₂
6 mole of KClO₃ will produce = 9moles of O₂
