C) S
Because of the trends of electronegativity. Increases across a period and decreases down a group.
Answer:You can view more details on each measurement unit: molecular weight of BaCl2 or grams This compound is also known as Barium Chloride. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles BaCl2, or 208.233 grams.
Explanation:
Answer: Scientists make designs based on engineering knowledge and
then make it available for public use.
The answer is B- Low reactivity.
Well, you would need to know how to properly name these chemical compounds and elemental compounds, specifically ionic compounds.
1. H2 + I2 -> 2HI - Synthesis
2. 2Li + 2HCl -> 2LiCl + H2 - SR - Single replacement
3. Na2CO3 -> Na2O + CO2 - Decomposition
4. 2HgO -> 2Hg + O2 - Decomposition
5. Mg(OH)2 -> MgO + H2O - Decomposition
6. Cu + Cl2 -> CuCl2 - Synthesis
7. Ca(ClO3)2 -> CaCl2 + 3O2 - Decomposition.
8. 2Li + 2H2O -> 2LiOH + H2 - Single Replacement Reaction.
