Answer:
The most common chemical properties are flammability and reactivity. Flammability looks very similar to a word that many of you have seen before: flame. In this case, flammability is the ability of a substance to burn or better yet, how easily something burns.
Explanation:
Like PERIODic table.). All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.
Answer:
is a reactant; it is present before the reaction occurs.
Explanation:
In a chemical reaction the chemical formulas written before the arrow are described as reactants as they react together to form products which are written after the arrow.
![CaCO_3 + 2HCl \rightarrow CaCl_2 + CO_2 + H_2O](https://tex.z-dn.net/?f=CaCO_3%20%2B%202HCl%20%5Crightarrow%20CaCl_2%20%2B%20CO_2%20%2B%20H_2O)
Thus
and HCl are reactants here whereas
,
and
are products.
