Answer:
Yes
Explanation:
If an object is flat and it falls it will go against the air (Air-Resistance) when falling down, which it will make the block go slower then a sphere which has no sides and will fall faster then the square or Block because there isn't a flat side it wont go against the air ( Air-Resistance).
Sodium lose one electron and convert into sodium ion Na+
Chlorine lose one electron and form Cl- ion
When these ions come together they from an ionic compound NaCl,
table salt
The ionic compound which consist ionic bond. The ionic bond is a type of bond which formed between positive and negative ions or metal, sodium and non-metal , chlorine
Answer:
your answer would be 0.3 meters
To get the meter you have to divide the length 30 value by 100
which will give you 0.3.
Hope this helped! Have an amazing rest of your day :)
To understand if the black crust on the silver coins signifies a chemical or physical change, you should determine if the substance's identity is altered. This is because a chemical change transforms the substance into a new material, while a physical change only alters its form. Knowing whether the crust changes the original silver coin's nature can differentiate between the two.
To discern whether the black crust on the silver coins signifies a chemical change or a physical change, you could ask: 'Can the black crust be removed to reveal the original silver coin beneath, without altering the silver coin's composition?'
This question is crucial because the main difference between chemical and physical changes on whether the substance's identity is altered. In a chemical change, substances are transformed into entirely new materials with different properties. An example of this is iron rusting. On the contrary, a physical change, such as ice melting into water, does not change the substance's fundamental nature, only its form.
If the black crust on the silver coins is a result of oxidation (combines with oxygen), similar to that in a rusting process, this would indicate a chemical change. However, if the black crust is merely tarnishing that can be polished off to reveal the same silver beneath, this would be an example of a physical change. Thus, understanding whether the crust alters the fundamental nature of the silver is important to differentiate between a chemical change and a physical change.
