A substance has a fixed volume. What else do you need to know to determine its state of matter?

Chemistry

Answer:

If it can change shapes easily.

Explanation:

A fixed volume eliminates gas as a possible state of matter, therefore leaving liquid and solid.

If the substance can easily change shape, it is a liquid. If it cannot change shape, then it is a solid.

Another way to determine the state of matter is through particle movement.

If particles slip past each other, it is a liquid. If particles vibrate in place, it is a solid.

What is the difference between Mixtures and Compounds? I am trying to study for my Science quiz on Tuesday, and I need to know t
Deffense [45]
A mixture can be separated.  Everything in a mixture keeps it's own properties and are not chemically joined together.  I am not completely sure about the compound.  Although with the cake example, the ingredients have been mixed and kind of "fused" together upon baking. Hope this helps a little. (P.S. trail mix is a good example of a mixture.)

Hanna hypothesizes that granite is denser than sandstone. How can Hanna test her hypothesis?
kherson [118]
To test if the hypothesis is correct, a good way is to think of it this way:
Density = mass/volume, right?
Calculate the mass and volume of each and do the equation; this will test your hypothesis.
You will be left with the density of each. But, make sure that the sample sizes are the same (controlled variable) otherwise it will be an unfair test.

How many grams of H2O are needed to produce 150 g of Mg(OH)2? (Molar mass: H2O = 18.02 g/mol; Mg(OH)2 = 58.33 g/mol )
Nuetrik [128]

Answer:

92.6

Explanation:

6 mol x 18.02 g of H2o --> 3 mol x 58.33 g  Mg(OH)2

108.12 g of h2o --> 174.99 of Mg(OH)2

g of H2O is 150 g of Mg(OH)2

150g x 108.12g / 174.99 =

92.67
