Which statements are true of heterogeneous mixtures? Check all that apply.

2 answers:

5 0

Answer: The correct statements are they settle out, they exhibit the Tyndall effect, they exhibit Brownian motion and they contain elements, compounds, and solutions.

Explanation:

Heterogeneous mixtures are defined as the mixtures which have non-uniform distribution. In this mixtures, there is a physical separation between the dispersed phase and dispersed medium.

The properties shown by these mixtures are:

They tend to settle out because there is a difference between the size of the particles.
They show Tyndall effect and Brownian motion.
These mixtures contain elements, compounds, and solutions.

Rest of the two statements are the properties shown by homogeneous mixtures.

The density of copper is 8.92 g/cm^3. If you plotted the mass of copper in grams versus the volume in cubic centimeters, what wo

dybincka [34]

The slope would be 8.92g/cm^3.

D = m/V

m = DV

The equation for a straight line is

y = mx +b, where m is the slope and b is the y-intercept. We have

m = DV + 0

Thus, a plot of m vs V will give a straight line with a slope of D and a

y-intercept at the origin.

Slope = D = 8.92g/cm^3

A. draw the structure of the tetrahedral intermediate initially formed in the reaction shown. you do not have to consider stereo

julsineya [31]

The reaction is shown below, Acid protonates the carbonyl oxygen and makes the carbonyl carbon more electrophilic. Water attacks on activated carbonyl group and forms a tetrahedral intermediate.

Intermediate:
Structure of Intermediate is shown both in 2-D and 3-D (below attached).

Carbonyl group is regenerated with the elimination of ethanol.

Reaction is as below, The final product is carboxylic acid.
