Answer:
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. ... The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

Answer:
0.009
Explanation:
Molarity, a measure of molar concentration of a substance is calculated thus;
Molarity = number of moles ÷ volume
According to the provided information, mass of KCl = 0.47g, volume of water = 700ml
Using mole = mass/molar mass
Molar Mass of KCl = 39.10 + 35.453
= 74.553g/mol
Mole = 0.47/74.55
Mole = 0.0063mol
Volume of water = 700ml = 700/1000 = 0.7L
Molarity = 0.006/0.7
Molarity = 0.00857
The value of molarity rounded to three decimal places (3 d.p) = 0.009
Spontaneous processes are processes that occurs freely they do not need any other external factors to be supplied for them to proceed while non-spontaneous ones requires input of energy for it to happen. Example of a spontaneous process is the decay of a diamond to graphite while the reverse of this is a non spontaneous process since heat and pressure are to be supplied for graphite to turn into diamond.
The atomic number represents the number of protons present in the nucleus of a certain atom. For a hydrogen atom, which has 1 proton, 1 electron, and 0 neutrons, the atomic number of hydrogen would be 1. The atomic number is the same as the charge number of a nucleus. This number is unique for every element in the periodic table and it distinguishes an element. In a neutral atom, this number is equal to the number of electrons in the atom. Also, the atomic number of an element determines the position of the element in the periodic table which for hydrogen, it is the very first element in the periodic table.
Magnified we see that the carbon atom VIBRATE in place.
When microscope is used to view the carbon atom at the atomic level, it was discovered that the atom vibrate in place. Each individual atom is spherical and have fuzzed edges.
