The kinetic energy of the particles increased.
Answer:
Mass of carbon = 236.5 g
Explanation:
Given data:
Mass of C₃H₆ = 275 g
Mass of C = ?
Solution:
Formula:
Mass of carbon = molar mass of carbon/ molar mass of compound × mass of compound
Molar mass of carbon = 12 g/mol
Molar mass of compound = 42 g/mol
Mass of carbon = 36 g/mol / 42 g/mol × 275 g
Mass of carbon = 0.86 × 275 g
Mass of carbon = 236.5 g
Explanation:
The charge of a helium atom is zero
It is neutral because
The number of unit negative charges = number of unit positive charges
One unit negative charge = -1.6 x 10^(-19) which is basically the charge of an electron
One unit positive charge = +1.6 x 10^(-19) which is basically the charge of a proton
A helium atom has 2 protons and 2 electrons, so it is neutral
NOTE: an alpha-particle (He2+) is a charged helium atom it has 2 protons and 0 electrons. Charge of an alpha particle = +3.2 x 10^(-19).
