At the Freezing Point the particles in an object have no kinetic energy
Water is the only one of these that would work by process of elimination.
Pesticides. They are known to be helpful for getting rid of pests and insects, but are also known to harm wildlife.
Answer:
Vanderwaals forces
Explanation:
CBr4 is a nonpolar molecule, nonpolar molecules usually possess vanderwaals forces between their molecules as their main attractive force.
CBr4 is nonpolar because the tetrahedral arrangement of the C-Br bonds cancel out the individual dipole moments of each C-Br bond thereby making the compound nonpolar, hence the answer above.
Explanation:
The fundamental particles in an atom are protons, neutrons and electrons. The given atoms are called the isotopes of magnesium. They only differ in the number of neutrons they possess.
Protons are the positively charge particles in an atom
Neutrons occupy the center of an atom with protons and they carry no charges
Electrons orbits an atom and they carry no charges.
For a neutral atom, the number of protons and electrons are the same.
Magnesium - 24
Magnesium - 25
Magnesium - 26
Magnesium is an atom on the periodic table with an atomic number of 12.
The atomic number is the number of protons in an atom.
The numbers in front of the problem given are the mass numbers.
For neutral atoms;
Number of protons = number of electrons = atomic number
Number of neutrons = Mass number - atomic number
Magnesium - 24
Protons = 12
Electrons = 12
Neutrons = 24 - 12 = 12
Magnesium - 25
Protons = 12
Electrons = 12
Neutrons = 25-12 = 13
Magnesium - 26
Protons = 12
Electrons = 12
Neutrons = 26 - 12 = 14
