The answer is A. Mixtures can be separated by physical means
A pure substance cannot be separated.
1. L
Number one because the lines match up
I think O and Cl will form covalent bonds since they are both non-metals and don't have a large enough difference in electronegativities to create an ionic bond.
I hope this helps. Let me know if anything is unclear.
Answer:
20 mol
Explanation:
First, balance the chemical reaction
C3H8 + 5O2 --> 4H2O + 3CO2
Using the mole ratio, we can multiply the moles of propane by 4 to find the moles of H2O.
5 × 4= 20
20 mol
I believe it's about the dislodging response as Ag structures solvent salt with nitrate. For dislodging response, more receptive metal will uproot less receptive metal from the arrangement. In your question, the reactivity of the metal are positioned as takes after: Mg > Cu > Ag. Take note of that more responsive metals, that are Mg and Cu, are in the arrangement.
