Answer:
Iron displaces copper ions
Explanation:
which means that iron in more reactive than copper.
(Fe2+) and cupric ion (Cu2 +) is converted into metallic copper. Fe (s) + Cu2 + (aq) —→ Fe2+ (aq) + Cu (s).
Answer:
When stargazers go outside at night to look at the sky, they see the light from distant stars, planets, and galaxies. Light is crucial to astronomical discovery. Whether it's from stars or other bright objects, light is something astronomers use all the time. Human eyes "see" (technically, they "detect") visible light.
Answer:
(c) an aqueous solution of CO2 exhibits dipole-dipole forces between solute and solvent
Explanation:
Co2 is a non-polar molecule.
It is actually shown to be O=C=O.
When dissolved in water to get aqueous solution.
Dipole on water molecule can induce dipole on CO2.
This entails that we should have dipole-induced dipole forces when we have a mixture or solvent and solute.
But the given statement states dipole dipole forces between solute and solvent.
Hence the statement is false.
Answer:
well tbh it's just the microwave doing its job heating up your Mac n cheese. But while doing so the Mac n cheese absorbs a lot of heat and then releases it by popping.
