Test tube of ammonium chloride (NH4Cl) being heated over a bunsen burner flame. Ammonium chloride decomposes readily when heated, but condenses in the cooler area at the top of the test tube. This is a reversible reaction, where the ammonium chloride decomposes into the gases ammonia (NH3) and hydrogen chloride (HCl).
Answer:
i think it cuz ones broken down by fision more
Explanation:
Answer:
The correct answer is B).
Explanation:
The factors that accelerate a chemical reaction are:
- Temperature: at a higher temperature, the speed of a reaction is increased.
- Pressure: the higher this is, the greater the collisions between molecules and an acceleration of the reaction speed will occur.
-Catalysts: correspond to substances that accelerate chemical reactions, an example are enzymes. There are catalysts that increase the reaction rate and others that generate the opposite effect (they are inhibitors).
There are also other factors that accelerate a chemical reaction such as the concentration of reagents.
Hello!
Answer:
Gravity
Explanation:
It can settle down and separate over time due to gravity.
Hope this helps! Have a great day!
Answer : The correct statement is:
The density of each piece is the same as that of the original block.
Explanation :
Intensive property : It is defined as a property of substance which does not change as the amount of substance changes.
Examples: Temperature, refractive index, density, hardness, etc.
According to question, if Ana has a block made of pure gold and she cuts this block into two equal pieces then the density of each piece is the same as that of the original block because density is an intensive property that does not changes until and unless material is changed.
That means density remains same as that of the original piece.
Hence, the correct statement is the density of each piece is the same as that of the original block.
