Answer:
Explanation:
There are some mistakes in writing the equation. However, Please check the below one and contact me again if necessary.
2KI(aq) + Pb(NO₃)₂ (aq) -> PbI₂ (s) + 2KNO₃
Answer:
c) 8 protons 10 electrons
Because there would usually be 8 of both, but in this case there has to be 2 more electrons to give it the ²⁻ charge
Answer:
Substances can be classified according to how these atoms are assembled and is known as Classification of Matter: All matter falls into one of three categories: elements, compounds or mixtures. Furthermore, mixtures can be classified as homogeneous or in homogeneous.
The atomic mass would be 13 amu.
You can calculate this by adding the number of protons and neutrons.
7 protons+6 neutrons
=13 amu.
The molar mass is what would you find on the periodic table and it is used in the mole conversions within chemistry. So the answer would have to be A: the mass in grams of one mole of a substance.
