Answer:
If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.
Explanation:
I hope it may help u
The answer is false. The particles in a suspension are not dissolved into the solvent rather they are suspended or dispersed into the solvent, Suspension is a heterogeneous mixture where solute-like particles settle out of a solvent-like phase. Examples are mercury in shake in oil, oil shake in water, and chalk in water.
Answer:
<em>K</em><em>+</em><em>Cl</em><em /><em>KCl</em>
Explanation:
because the reaction is between metal Potassium and Non-metal Chlorine
Answer: The mass of the sample having 2.1 kg of
will be ![2.1\times 10^{12}ng](https://tex.z-dn.net/?f=2.1%5Ctimes%2010%5E%7B12%7Dng)
Explanation: We are given a sample of sodium bicarbonate
having mass 2.1 kg
To convert this into nano-grams, we use the following conversions:
1 kg = 1000 grams
and
![1g=10^9nanograms](https://tex.z-dn.net/?f=1g%3D10%5E9nanograms)
Converting 2.1 kg to nano-grams using above conversions:
![2.1kg=2.1\times (1000\times 10^9)ng=2.1\times 10^{12}ng](https://tex.z-dn.net/?f=2.1kg%3D2.1%5Ctimes%20%281000%5Ctimes%2010%5E9%29ng%3D2.1%5Ctimes%2010%5E%7B12%7Dng)
Answer:
Metallic bonding
Explanation:
Metallic bonding
These type of bonding is observed between the delocalized electrons and the metal cations and is a form of electrostatic bond .
The substance that show these type of bonding , i.e. ,metallic bonding are malleable in nature , because ,
These substance can be moulded to give various shapes ,
As, the layers of atoms can slide on each other and therefore shows the property of malleability.
Hence, from the given information of the question ,
The correct type of bonding is metallic bonding.
