3K2CO3 + 2Fe(NO3)3 > 2K3(NO3)3 + Fe2(CO3)3
Explanation:
Brass (a copper-zinc alloy)-The brass bond is brittle because it is a metal alloy.
Rubber-Rubber bonding is covalent.
Barium sulfide (BaS) — Bonding is primarily ionic (but some covalent) depending on the respective Ba and S positions in the periodic table.
Solid xenon-Bonding is van der Waals in solid xenon, since xenon is a noble gas.
Bronze-Bonding is metallic in that it is an alloy with silver.
Nylon-The bonding in nylon is primarily covalent with some van der Waals Forces.
Aluminum phosphide (AlP)-Aluminum phosphide (AlP) bonding is covalent in principle but it also has some ionic character.
From the experiment it can be concluded that a material or object which has a density that is lesser than water floats. Also, the object that has a density greater than that of water will sink. This is because density is the measure of the amount of substance that is occupied by an object in a given volume.
Answer:
2.5 mole of O2
Explanation:
From the equation we see that we need 5 molecules of oxygen to react with 2 molecules of C2H2.
This means that 5 moles of oxygen molecules are needed to completely react with 2 moles of C2H2, because a mole is a unit of particle count.
From that we can infer that to react with 1 mole of C2H2 we need half of 5 moles of oxygen - so 2.5 mole of oxygen molecules.
A) mixture because they are not chemically combined
