Answer:
The correct answer is - d. single replacement or displacement.
Explanation:
The displacement or replacement reaction is the reaction in which the less reactive molecule or element is replaced by the more reactive element or molecule in the reaction. If there is only one replacement occurs its termed as a replacement or single replacement reaction.
In this case, if chlorine gas passes through the water solution of KI (potassium iodide), solid iodine and KCl are produced by the displacement or replacement reaction. Here iodine is less reactive so replaced by the more reactive chlorine.
2KI(aq)+Cl2
(g)→2KCl(aq)+I2

Answer:
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. :)
Explanation:
<em>It izz wat it izzzz!!!</em>
Mass of object A = 10g
volume of object A = 8cm³
Mass of object B = 10g
Volume of Object B = 6cm³
we use the following formula to calculate the density of object A and B.
Density = Mass / Volume
Density of Object A = 10g / 8cm³ = 1.25g/cm³
Density of Object B = 10g / 6cm³ =1.67 g/cm³
So the density of object B is greater than object A
and if we find the difference:
1.67 - 1.25 = 0.42
So the answer is; Object B, by 0.42 gram per cubic centimeter
Answer:
addition polymerization
Explanation:
In addition polymerization, the monomers are simply joined to each other to form a polymer having the same empirical formula as the monomer but of higher relative molecular mass. The monomers in addition polymerization are usually simple unsaturated molecules such as alkenes.
We can deduce the reaction to be an addition polymerization because of the the attachment of n to both the unsaturated monomer and the saturated polymer without the loss of any small molecule. If it was a condensation polymerization, there would have been an accompanying loss of a small molecule such as water.
