=1200/(54.9*3)+7[32.1+(16*4)]
=1.433
Answer:
Explanation:
Chemical properties of atoms relies solely on the number of electrons they contain, more particularly, the valence or outermost electrons in the orbit round the nucleus of an atom.
A neutral atom is one that has not gained or lost electron or even shared electrons with any other atom.
On close examination of how electrons are distributed in the orbits of an atom, we can know if an atom will gain or lose electrons in a reaction. This is very important in determining the chemical properties of an atom.
Answer:
Probably answer D.
Explanation:
It makes the most sense because it's just changing the temp of the water
Answer:
Gay-Lussac's law states that pressure and temperature are directly proportional
Explanation:
Gay-Lussac's law states that pressure and temperature are directly proportional. This always occurs if the volume keeps in constant.
n and V are not directly proportional, they are the same.
At Charles Gay Lussac's law
V1 = V2
n1 = n2
T1 < T2
P1 < P2
P1 / T1 = P2 / T2
If the pressure is contant:
V1 / T1 = V2 /T2
Answer:
A variable shape that adapts to fit its container.
