Answer:
they are equal
Explanation:
the Law of Conservation of Mass states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change
Answer:
At a front, the two air masses have different densities, based on temperature, and do not easily mix. One air mass is lifted above the other, creating a low pressure zone.
Explanation:
Hope this helps!
All of them are soluble salt.
First one dissociates into two ions.
The second one dissociates into 3 ions.
The third dissociate into 4 ions. therefore, Al(NO3)3
Answer:
Explanation:
Electronegativity is a measure of the ability of an atom to attract the electrons when the atom is part of a compound. Electronegativity values generally increase from left to right across the periodic table. The highest electronegativity value is for fluorine.
Ernest Rutherford's gold-foil experiment showed the density of atoms.
<span>The experiment proved that most of an atom is empty space with a very small positively charged nucleus in the middle.
So, from the given statements he following is true:
</span><span>Ernest Rutherford's gold-foil experiment showed </span>the existence of a dense, positively charged center in an atom.
