Its not always accurate because you dont know what they could have done to it before they try to sell it
Calcination use temperatures roughly twice that of typical roasting. The main idea is to use high temperatures and decompose the material being heated fairly faster. Roasting tries to changes the food products by starting and supporting a number of chemical reactions within the food that results in pleasant flavor, greater availability of certain ingredients.
2NaCl + Br2
This is because Na (Sodium) still needs to retain the coefficient or amount of two. Since Chlorine already has 2 on the reactants side, having a two in front would make sense so both elements can have a two.
Bromine would have the subscript of two as in the reactants side of the equation, it is also under the coefficient of two. Thus, it would need to carry it to the products side in order to keep the equation balanced.
Hope this helps!
Answer:
Cl⁻ was oxidized.
Explanation:
- 4HCl + MnO₂ → Cl₂ + 2H₂O + MnCl₂
Oxidation can be defined as the process in which the oxidation number of a substance increases.
On the left side of the equation, Cl has a charge of -1 (in HCl); while on the right side of the equation Cl has a charge of 0 in Cl₂.
Thus, Cl⁻ was oxidized.
Answer:
C). Electrostatic attractions between + and - charged ions.
Explanation:
They're electrostatic attractions because it is electrovalent bonding.
