mestny [16]

Answer:

3Ca₍s₎ + 2FeCl₃ ------------------------------------------------------------->  3CaCl₂ + 2Fe₍s₎.

Explanation:

Iron(III) chloride is also known as Iron trichloride and it has the molar mass value of 162.2 g/mol and density of 2.9 g/cm³.

<em>The balanced equation for the chemical reaction between solid calcium and iron (III) chloride is given below as:  </em>

<em />

3Ca₍s₎ + 2FeCl₃ ------------------------------------------------------------->  3CaCl₂ + 2Fe₍s₎.

This kind of chemical reaction is known as <em>single displacement reaction or single replacement reaction. </em>

2. A 10 kg ball is rolled down a rail from a height of 20 m. What is the velocity at the bottom of the
solmaris [256]

Answer:

19.8m/s

Explanation:

Given parameters:

Mass of the ball  = 10kg

Height of the rail  = 20m

Unknown:

Velocity at the bottom of the rail  = ?

Solution:

The velocity at the bottom of the rail is its final velocity.

Using the appropriate motion equation, we can find this parameter;

   V²   = U²  + 2gH

V is the final velocity

U is the initial velocity

g is the acceleration due to gravity

H is the height

  the ball was rolled from rest, U  = 0

  V²  = O²  + 2 x 9.8 x 20

 V  = 19.8m/s

 <span>You have to use a Newman projection to make sure that the H on C#2 is anti-coplanar with the Br on C#1. (Those are the two things that are going to be eliminated to make the alkene.) 

My Newman projection looks like this when it's in the right configuration: 
Front carbon (C#2) has ethyl group straight up, H down/left, and CH3 down/right 
Back carbon (C#1) has H straight down, Ph up/left, and Br up/right. 

Then when you eliminate the H from C#2 and the Br from C#1, you will have Ph and the ethyl group on the same side of the molecule, and you'll have the remaining H and CH3 on the same side of the molecule. 

This is going to give you (Z)-2-methyl-1-phenyl-1-butene.</span>
