Atomic number is written in subscript:
Uranium atomic number =92
Mass of neutron is the superscript value times the quantity (moles):
3*1= 3
Atomic mass is approximately equivalent to the number of protons and neutrons in the atom (the mass number). It's written in superscript:
Kr=92
No. of neutrons = Mass number (in superscript) - Atomic number ( in subscript)
= 141-56= 85
No. of neutrons in reactants are: 3
Answer:
faster, and the ingredient will be a liquid.
Explanation:
Iron filings can be attracted by the magnet whereas salt can not. So the mixture can be separated by a magnet
Answer:i think there is a spark
Explanation:
Answer:
The new volume of the gas is 32L
Explanation:
P1 = 16atm
V1 = 4L
P2 = atm
V2 = ?
According to Boyle's law, the volume of a given mass of gas is inversely proportional to its volume provided the temperature remains constant.
P1 * V1 = P2 * V2
V2 = (P1 * V1) / P2
V2 = (16 * 4) / 2
V2 = 64 / 2
V2 = 32L
The new volume of the gas is 32L
