Answer:
the last period. i think has the largest energy level
Explanation:
Answer:
They are all the same = 8
Explanation:
Since the symbol of that atom is not give, we can infer from the given number the nature and kind of element we are dealing with.
The number 15.999 rounded up to 16 is the atomic weight of the atom also called the mass number.
Although not peculiar enough, we are certain that this atom is Oxygen.
On the periodic table, elements are arranged based on their atomic numbers.
Atomic number of oxygen = 8 = number of protons
For every neutral atom on the periodic table, the number of protons and electrons are the same
Atomic number of oxygen = number of protons = number of electrons = 8
Number of neutrons = Mass number - atomic number = 16 - 8 = 8
Answer: A - Propanone and ethanal.
Explanation:
Aldol condensation may be defiend as a reaction which involves an enol or an enolate ion with a carbonyl compound to form a beta-hydroxyaldehyde (β-hydroxyaldehyde or β-hydroxyketone), which is accompanied by dehydration to give a conjugated enone.
In this case, Propanone and ethanal will undergo condensation reaction to produce pent-3-ene-2-one.
It is important to note that propanone is an enol.
Therefore, the pair of reactants that will undergo aldol condensation to produce pent-3-ene-2-one? is Propanone and ethanal.
Answer:
Well, there many conditions.
Explanation:
One of them is, religious reasons and the other is because it may be a risk and be a big impact, (in a bad way) on the women. (since some places, people see abortion unpleasant and immoral)
Btw, I got this info from google and gathered it to make this, so if this is wrong then sorry.
Answer:
A solution of NaOH has concentration 1.2M. Calculate the mass of NaOH in g/dm3 in this solution. = 1.2x 40x 1 = 48 g 3.
