Answer:
The composition of a nuclide (atomic nucleus) is defined by the number of protons Z and the number of neutrons N, which sum to mass number A.Proton number Z, also named the atomic number, determines the position of an element in the periodic table.The approximately 3300 known nuclides are commonly represented in a chart with Z and N for its axes and the half-life for radioactive decay
Explanation:
Answer:
limiting reactant is aluminum
Explanation:
That is True XD
Hope that helps :D
it is important to check the conductivity and pH of pure water to:
1- to check the purity of water and if it healthy or not , and the water source.
2- we have to measure the PH to know the alkalinity or acidity of water. If the PH > 7 so it is acidic , if PH < 7 so it is alkaline.
3- we have to measure the conductivity of the water as it is an indication for the impurity level. and it shouldn't be high to keep the water healthy.
