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
(s)
<span>The answer is melting and freezing point. At the melting point the solid and liquid stage occur in equilibrium. The melting point of a material hinge on pressure and is typically quantified at standard pressure. When measured as the temperature of the opposite alteration from liquid to solid, it is denoted as the freezing point.</span>
According to Gay-lussac’s law, if the temperature of a gas increases, then the the pressure ALSO INCREASES.
Answer:
5
Explanation:
Given parameters:
Width of wedge = 2inches
Length of sloped side = 10inches
Unknown:
Mechanical advantage = ?
Solution:
A wedge is a simple machine used to split devices into two. It is a simple chisel.
The input force is through the width and the output wok done is through the length of the slope.
Mechanical advantage is the ratio of the output force to the input force;
M. A = 
therefore;
M.A = 
= 5
Mechanical advantage has no unit.
