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.

Which sentence is a scientific statement?
LekaFEV [45]

Solution: Sentence D is a scientific statement.

Scientific statement is a statement that defines the science behind any situation. There should be any experimental result or observation to state any scientific statement. Also, the statement should be accepted by considering other scientific aspects.

Here, statement A can not be a scientific statement as different aromas of cooked food are liked by different people. Any one can find aroma of cooked food in copper better than the ceramic pot.

Thus, the statement can be proved wrong easily.

Statement B can not be a scientific statement as people can find the taste of normal water (without ice cubes) better than the ice cold water.

Statement C is not a scientific statement as there is no science behind watching baseball or ice hockey, it depends on the liking of today's people.

Statement D is a scientific statement because this can be scientifically proved.

A jeweler guarantees that a piece of jewelry is at least 95% gold, by mass. You consider buying a piece of gold jewelry that wei
ELEN [110]
The density of the sample is:
Density = mass / volume
Density = 9.85 / 0.675
Density = 14.6 g/cm³

If the sample has 95% gold, and 5% silver, its density should be:
0.95 x 19.3 + 0.05 x 10.5
Theoretical density = 18.9 g/cm³

The difference in theoretical and actual densities is very large, making it likely that the jeweler was not telling the truth.

QUICK HELP PLEASE!!?? Need answer QUICK
d1i1m1o1n [39]

Answer:

B

Explanation:

Look on the x-axis for the tick marked "60". This indicates 60 degrees Celsius, which we want. Now, look on the y-axis for the tick marked "60". This indicates 60 grams of Na_2HAsO_4. Trace along the graph to find where these two places meet at (60, 60).

Now, look for the solubility curve of Na_2HAsO_4; it's the yellow-orange line. Find out what the y-coordinate of the point where x = 60 is on the line: it's around (60, 65).

So, since the point (60, 60) is below the line corresponding to this substance, Na_2HAsO_4 is unsaturated.

The answer is B.
