The state of the substance, most likely, would be a gas. Given the same amount of the substance being able to fill different volumes of containers, means that the substance is compressible. From the three phases of matter, gas is surely the compressible one while liquids are sometimes compressible but only up to certain extent. Also, the substance cannot be a a solid since a solid would have a definite shape and volume. Nor it cannot be a liquid since a liquid cannot fill the whole container and it does not change its volume no matter what is the container.
You can identify a substance, by testing the melting and boiling point and find a known substance that has the same melting and boiling points as the one tested
Answer:
Theoretical yield = 3.75g
Explanation:
Percent yield is defined as one hundred times the ratio between actual yield and theoretical yield. The expression is:
Percent yield = Actual Yield / Theoretical Yield * 100
In the problem, your actual yield was 3-00g.
Percent yield is 80.0%.
Solving for theoretical yield:
80% = 3.00g / Theoretical yield * 100
Theoretical yield = 3.00g / 80.0% * 100
<h3>Theoretical yield = 3.75g</h3>
The answer to the question stated above is cumulus clouds.
<span>When looking up at the clouds, you can usually make out different shapes and figures with cumulus clouds.
</span>Cumulus <span>low-level clouds. They </span>are the puffy, white, cotton-top clouds that look so soft.
c. physical change
Explanation:
The separation of ink into its different pigments during chromatography is a physical change.
Ink is a mixture of many different pigments.
During chromatography, a mixture is separated based on the relative migration of constituents of mixture over an adsorbent.
- Separation techniques are used to celebrate mixtures based on their physical properties.
- During a physical change only the physical properties of matter like their form and state is changed.
- The process is easily reversible and no new kinds of matter are formed.
