Answer:
Atoms are composed of electrically charged particles and moving electric charges possess an associated magnetic field.
Explanation:
An atom is made up of electrons arranged in shells. Electrons are negatively charged. These charged particles produce an electric field which can interact with an external electric field to give information about atomic structure.
Similarly, a moving electron produces an associated magnetic field which can couple with an external magnetic field to give information about atomic structure.
Answer:
K2CrO4
Explanation:
To find the empirical formula, we need to divide each element by its atomic mass. The atomic masses of potassium, chromium and oxygen are 39.0983, 51.9961 and 15.999 respectively. We make the divisions as follows:
K = 1.04/39.0983 = 0.027
Cr = 0.70/51.9961 = 0.013
O = 0.86/15.999 = 0.054
We now divide by the smallest which is the number of moles of the Chromium
K = 0.027/0.013 = 2
Cr = 0.013/0.013 = 1
K = 0.054/0.013 = 4 approximately
The empirical formula is thus:
K2CrO4
Explanation:
Limostone is a sedimentary rock composed mainly of calcium carbonate (CACO3),generally calcite,although it frequently has traces of magnesite (MGCO3)and others carbonates.
1,2-methylcyclohexane, 1,3-methylcyclohexane, 1,4-methylcyclohexane
The minerals?
when an acid reacts with a base it forms salts depending on the acids and bases reacted it will determine its formula
for example HCl + NaOH = NaCl + H20
