Answer:
(Co,Fe)As2
Explanation:
The formula of the mineral safflorite, a compound made of cobalt, iron, and arsenic is (Co,Fe)As2. This itself is the imperical formula, it cannot be divided any further
The equation for the reaction between Ca3N2 and Al2O3 wiil be;
Al2O3 + Ca3N2 = 2AIN +3CaO
Thus, the products of the reaction will be Aluminium Nitride and Burnt lime(Calcium oxide). A double displacement reaction, also known as a double replacement reaction or metathesis, is a reaction where two compounds react, and the positive ions and the anions switch places, forming two new compounds or products.
Answer: 2LiBr(aq) + F2(g) —> 2LiF + Br2
explanation: Br and F are both nonmetals. Nonmetals should only replace other nonmetals in a single replacement reaction.
Answer:
Sulfur is NOT a metal.
Explanation:
Out of all the options the one that is NOT a metal is s. Sulphur has characteristics of nonmetals. It does not have luster, it cannot conduct electricity, and it is brittle. On the periodic table, sulphur is in group 16/VIA, in the third period.
