Why does the chemical composition of water always stay the same?
The chemical composition of water, H2O, remains the same because it is a pure substance with a fixed ratio of hydrogen to oxygen atoms. Water molecules consist of two hydrogen atoms covalently bonded to one oxygen atom, and this arrangement is stable and does not change under normal conditions.
What always stays the same in a compound?
a compound always has the same chemical formula
What happen to the bonding of atoms in a physical change?
In a physical change, the bonding between atoms remains intact. The change involves the rearrangement of atoms or molecules without breaking or forming new chemical bonds. This means the fundamental structure and composition of the substance remain the same.
What are the signs of physical change and chemical change?
Physical Change: A change in which the atoms or molecules in a substance stay the same. Example: Ripping a piece of paper in half Chemical Change: A change that affects the type of molecules or atoms in a substance. Example: Burning wood The primary difference is that in a physical change, the composition of the substance remains the same, but in a chemical change, the composition of the substance changes.
How Does the total amount of matter in a substance increase decrease or stay the same after a chemical or physical change?
The total amount of matter in a substance remains the same after both chemical and physical changes. This is known as the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction or physical change, only rearranged. So, the total mass of the substances before and after the change will be equal.
Will density always stay the same no matter what size the object is?
Density of the substance will always stay the same. Density of the object will also stay the same if solid, no matter the size, but not if it is carved out. That is why a steel boat can float
What reaction of matter will stay the same during a physical change?
The chemical composition of the matter will stay the same during a physical change. Only the physical properties, such as shape, size, or phase, will be altered without affecting the chemical composition of the substance.
Why does the chemical composition of water always stay the same?
The chemical composition of water, H2O, remains the same because it is a pure substance with a fixed ratio of hydrogen to oxygen atoms. Water molecules consist of two hydrogen atoms covalently bonded to one oxygen atom, and this arrangement is stable and does not change under normal conditions.
What always stays the same in a compound?
a compound always has the same chemical formula
What happens if a substance of unknown composition is heated in a sealed container As a result the mass of the container and its contents?
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.
What will not change the state of matter?
Factors such as the amount of a substance, its chemical composition, and the presence of impurities will not change its state of matter. For instance, heating or cooling a substance can change its state (e.g., solid to liquid), but simply having more or less of the same substance at the same temperature and pressure will not alter its state. Additionally, the state of matter remains unchanged as long as the temperature and pressure conditions stay constant.
How can you decide if a reaction is a Chemical reaction?
Chemical change is when the composition of your elements or solution change. In a simple way to say it, it's when you no longer have the same elements or solution that you started with. You can determine if a reaction is chemical, by observing the chemical properties. Usually it's when there's a color change, a new substance formed, etc.. On the other hand, physical change is when the composition of your substance stay the same, but the physical properties change. For example, liquid water evaporate into H2O gas.
Does the mass of an object always stay the same?
Yes
What factors in an experiment always stay the same?
k
Why does voltage increase and not stay the same in mutual induction?
Well the same reason fire doesn't stay at the same temp. is always changing
Does you mass always stay the same no matter what?
Yes, no gas is given off, therefore the mass of conversation will stay the same.
What is Abby in Spanish?
Abby, names always stay the same
