Answer:
MnO- Manganese Oxide
Explanation:
Empirical formula: This is the formula that shows the ratio of elements
present in a
compound.
How to determine Empirical formula
1. First arrange the symbols of the elements present in the compound
alphabetically to determine the real empirical formula. Although, there
are exceptions to this rule, E.g H2So4
2. Divide the percentage composition by the mass number.
3. Then divide through by the smallest number.
4. The resulting answer is the ratio attached to the elements present in
a compound.
Mn O
% composition 72.1 27.9
Divide by mass number 54.94 16
1.31 1.74
Divide by the smallest number 1.31 1.31
1 1.3
The resulting ratio is 1:1
Hence the Empirical formula is MnO, Manganese oxide
Answer:
Neutral.
Explicación:
Cuando dos cargas negativas, dos cargas positivas y una carga positiva y una carga negativa se unen, los átomos se vuelven neutrales porque las cargas opuestas cancelan el efecto de la otra. Si hay igual número de cargas y además son opuestas entre sí, entonces todas estas cargas cancelan el efecto de la otra formando el átomo neutral, pero si hay diferencia en el número de cargas, entonces la carga que es alta en número aparece en el átomos.
Answer:
a number assigned to an element in chemical combination which represents the number of electrons lost (or gained, if the number is negative), by an atom of that element in the compound
Explanation:
sodium, magnesium, iron is zero.
Answer:
No, Mercury can actually cause poisoning. That is why other metals, such as Alkaline metals, are used in making batteries
