Answer:
reactivity
Explanation:
a chemical reacting to another chemical is considered a Chemical property because chemicals react with other chemicals differently
Answer:
D) 1 iron(II), 2 chloride
Explanation:
Iron II chloride is the compound; FeCl2. It is formed as follows, ionically;
Fe^2+(aq) + 2Cl^-(aq) -----> FeCl2
The formation of one mole of FeCl2 involves the reaction one mole of iron and two moles of chloride ions. This means that in FeCl2, the ratio of iron to chlorine is 1:2 as seen above.
Therefore there is one iron II ion and two chloride ions in each mole of iron II chloride, hence the answer.
7 valence electrons, because carbon has 5 electrons and nitrogen can have either 3 or 5, but because it cannot fill more than 8, we must assume those added together will equal 7
Explanation:
Protons are the positively charged particles found in an atom.
- A proton is found within the nucleus of an atom.
- Together with the neutron, they make up the nuclear region of an atom.
Protons and neutrons constitutes the bulk mass of the atom.
The mass of a proton is 1.67 x 10⁻²⁷kg
The proton have the same mass as neutrons.
Compared to electrons, it is 1840 times the mass of an electron.
