Metals, especially iron, have this form of electron cloud around it. When it's placed in a magnetic field these electrons line up
Answer:
2C2H6 + 7O2 → 4CO2 + 6H2O
Explanation:
Combustion is when a hydrocarbon (a compound made of only hydrogen and carbon) reacts with oxygen at high temperature to produce CO2 and H2O gases.
Radio waves have the longest wavelength
Answer:
The substance is Mercury. It has 80 electrons revolving around nucleus and 80 protons inside nucleus.
Explanation:
Atomic number of atom represent the number of electrons and protons of the atom. Thus,
Number of electrons = number of protons = 80
The atom which has atomic number 80 in the periodic table is Mercury.
Answer:
Explanation:
potential energy of water is converted into heat energy
P E = mgh = m x 9.8 x 111
= 1087.8 m .
Let rise in temperature θ
m x s x θ = heat absorbed
m x s x θ = 1087.8 m
m x 4182 x θ = 1087.8 m
θ = 0.26 degree celsius .
