Answer:
4. Another element is formed with greater atomic number
Explanation:
Ions only have a different amount of electrons and have the same amount of protons and neutrons.
Isotopes only have a difference in neutrons.
However, only a difference in protons will make another element.
Hence, 4 is the answer.
Hope this helped!
Whats the reaction? There should be a written out reaction that yields something
Answer:
3,meta, ortho, and para-nitrobenzoic acid, when the nitro group is 1, 2, or 3 carbons away from the carboxyl on the benzene ring
There are 3 dinitrobenzenes, o-dinitrobenzene, m-dinitrobenzene, and p-dinitrobenzene.
1st is benzyl alcohol, the second is anisol.Three more are o-methylphenol, m-methylphenol, and p-methylphenol which contain a linear formula
Explanation:
The reaction between zinc and silver nitrate is
Moles of Zn = m /M = 599 /65 = 9.2 mol
Moles of AgNO3 = m /M = 1500 /169 = 8.87 mol
Silver nitrate is reacting completely to give silver
Thus, moles of Silver nitrate is equivalent to silver = 8.87
For mass of silver produced
m /M = 8.87 = m /107
m = 949.24 g
Hence, the given quantity of reactants are sufficient to produce 800 g of silver as the amount of silver produced is 949.24 g
Answer:Convection currents drive the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle. In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig. 7.21).
