For the answer to the question above, asking to w<span>rite the complete balanced equation for the reaction between aluminum metal (Al) and oxygen gas (O2)and You do not need to make the subscripts smaller.
My answer would be,
</span><span>4Al(s) + 3O2(g) --->2 Al2O3(s)
</span>
I hope this helps.
A functional group is a group of atoms that determines many of the properties of an organic molecule.
For example functional group for alcohol is hydroxyl group (-OH) and for carboxylic acid is <span>carboxyl group (-COOH).
</span>Alpha carbon is <span>the first </span>carbon<span> atom after the carbon that attaches to the functional group.</span>
Answer:
commensalism, mutualism, parasitism
Given
Mass number of isotope = 63
Number of neutrons = 33
So number of protons = 63 - 33 = 30
Hence atomic number of metal = 30
thus metal is = zinc
now as it is forming cation with 28 electrons it means it has lost two electrons so it must have a dipositive charge
the symbol of metal ion will be
Zn^+2
3 km/h
formula for momentum = mass x velocity
