1 A1Br3 + 3 K = 3 KBr + 1 A1
the answer is A. SnCl2 . 2H2O
Answer: 6.1 g
Explanation:
between Mg and MgO theres a 1;1 MOLE RATIO
here's the balanced equation
2Mg + O2 ==> 2MgO
24g of magnesium is approximately 1 mole of magnesium so it produces 40 g of mgo which is also 1 mole of mgo thus 10/40 =0.25 moles of MgO so 0.25 moles of magnesium would be needed which is approximately 6.1 g
(A.) Nickel and oxygen reacting chemically could create a compound. (Most likely some sort of oxide)
The pure silver is only made up of one element, so it can't be a compound.
The sandwich and all it's components may contain chemical compounds, but is not a compound in itself.
