If a substance of unknown composition is heated in an open container will Its mass will stay the same as a result the mass of the container and its contents decreases. A substance of an unknown composition is heated in a sealed container the mass of the container and its content remains the same.
I think the answer is yes because I just think it is.OKAY!Gosh don't judje my life!
The mass remain constant: this is the law of mass conservatin.
Notes: avoided reactions between the container and the substance, also explosions.
decreases
Physical changes, such as the change from ice to water to steam; the compound remains as H2O in all three states.
Atoms are rearranged, heat may be given off, changes in color and odor might occur, or a gas or precipice may be formed. The composition is changed, and the above are signs of a chemical change.
the chemical composition does not change.
Then the substance in the container becomesa mixture of hot dirt in hot water.
A physical reaction, or change, is one that can be observed without changing the chemical composition of the substance. Boiling is a physical change because the substance that is boiling does not change its chemical composition. For example, water is still H2O whether it is boiling or not boiling.
When a substance changes state, Energy within the substance is gained or lost, but the composition is unchanged.
Nothing. Melting is a physical change and does not alter the chemical composition of a substance.
I dont know but you better find out
Physical changes, such as the change from ice to water to steam; the compound remains as H2O in all three states.
provided neither substance is hot or cold enough to cause the other substance to change state, the liquid will conform to the container it is in, if it is not in a container, it will flow with the path of least resistance. Just pour some water on a rock... come on.
If a liquid is not in a container it will evaporate.
They clog your arteries and turn into a goo like substance, the poo-like juice will flow to your heart and within seconds you'll die. Take a tums.
Atoms are rearranged, heat may be given off, changes in color and odor might occur, or a gas or precipice may be formed. The composition is changed, and the above are signs of a chemical change.
What happens is the composition of the compound becomes different and the composition of the mixture stays the same because you can have many types of mixtures.
the chemical composition does not change.
what happens is that the heat gets trapped in the container and it turns foggy
Then the substance in the container becomesa mixture of hot dirt in hot water.
