1. a compound is when the atoms of different elements are chemically held to one another. a mixture is a substance that has two or more different materials in such a way that no chemical reaction occurs.
A mixture can usually be separated back into its original components, a compound can not.
Example of mixture: salt water, because you can evaporate the water and get the salt. it is not chemically held together.

Example of a compound: H2O(water) you cant seperate the hydrogen and oxygen


2. the size of the sugar particles are probably extremely small because it is dissolved

3. the ice cubes are bigger. if you want to remove the sugar, you would have to evaporate the water.

grandymaker [24]
Answer:
             <span>A geometric isomer with two alkyl groups on the same side of the carbon-carbon double bond is called <em>cis</em> Isomer.

Explanation:
                   Geometric isomerism takes place about the double bond in alkenes when the alkyl groups are either situated at the same side (<em>cis</em>) or are situated opposite (<em>trans</em>) to each other.

Example:
               <em>cis</em>-2-Butene (highlighted red)

               <em>trans</em>-2-Butene (highlighted blue)</span>

Alex dragged a log across the yard in 30 the log weighted 400n she did 900 j of work how much power did I she have
In-s [12.5K]

The power used by Alex to drag the log across the yard is determined as 2,656 W.

<h3>Mass of the log</h3>

The mass of the log is calculated as follows;

W = mg

m = W/g

m = (400)/9.8

m = 40.82 kg

<h3>Velocity of the log</h3>

K.E = ¹/₂mv²

v² = 2K.E/m

v² = (2 x 900)/(40.82)

v² = 44.096

v = 6.64 m/s

<h3>Power used by Alex</h3>

P = Fv

P = 400 x 6.64

P = 2,656 W
